Neutral is not always pH 7 Conversely, if a solution is neutral, that does not guarantee that it is also at pH 7. For example, at a temperature of 50oC, Kw = 5.47 × 10−14, giving a pH of 6.63.

A solution of pH 3 will have 100 times more H+ (it is 100 times more acidic) than a solution of pH 5.

The pH scale is logarithmic, meaning that an increase or decrease of an integer value changes the concentration by a tenfold. For example, a pH of 3 is ten times more acidic than a pH of 4. Likewise, a pH of 3 is one hundred times more acidic than a pH of 5.

What does it mean for a solution to be acidic or basic (alkaline)?

Any solution that has a pH of less than 7 is considered acidic, and anything above a pH of 7 is basic.

pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

The normal range for urine pH is 4.5 to 7.8. Very alkaline urine (pH > 7.0) is suggestive of infection with a urea-splitting organism, such as Proteus mirabilis. Prolonged storage can lead to overgrowth of urea-splitting bacteria and a high urine pH.

Some people say that drinking slightly alkaline water — with a pH between 8 and 9 — can improve your health. They say it may make you age more slowly, maintain a healthy pH in your body, and block chronic disease like cancer.

A urine pH of 8.5 or 9.0 is indicative of a urea-splitting organism, such as Proteus, Klebsiella, or Ureaplasma urealyticum; therefore, an asymptomatic patient with a high pH means UTI regardless of the other urine test results.

Abnormal: Some foods (such as citrus fruit and dairy products) and medicines (such as antacids) can affect urine pH. A high (alkaline) pH can be caused by severe vomiting, a kidney disease, some urinary tract infections, and asthma.

Normal Results The normal values range from pH 4.6 to 8.0. The examples above are common measurements for results of these tests. Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples.

6.5 to 8.5

The pH of your water should only matter if it’s caustic enough to hurt you. Most commercial uncontaminated bottled water won’t make you healthier or sick due to its pH. Depending on the source and processing, most bottled water stays between a pH of 5 to 8.

Because alkaline water has a higher pH level than does plain tap water, proponents say that it can neutralize acid in your bloodstream. However, research suggests that alkaline water is unlikely to significantly change blood pH.

Signs and symptoms of an unbalanced vaginal pH

1. a foul or fishy smell.
2. unusual white, gray, or green discharge.
3. vaginal itching.
4. burning when you urinate.

A diet high in fatty acids may aid in producing additional vaginal lubrication. Raw pumpkin, sesame seeds, sunflower seeds, and fish (especially salmon, mackerel and tuna) are great choices that are high in fatty acids.

6 foods to get you in the mood

• Avocado. Throughout history, men and women alike have used food to lure a lover.
• Asparagus. Asparagus, with its phallic shape, meets Hopkins’ visual criteria for an aphrodisiac.
• Maca powder. Maca is “a powerful sex enhancer,” Kilham says.
• Ginger.
• Oysters.
• Chocolate.

1000 times

Is it 10 times as acidic as pH 8? 1000 times. As pH of 4 implies concentration of protons to be 10^(-4) and pH of 7 implies the concentration of protons to be 10^(-7) which are related by a factor of 1000. This means that it’s a logarithmic scale with a base 10.

A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6.

The higher a substance’s pH, the more basic or alkaline it is. Each whole pH value above 7 is ten times more alkaline (another way to say basic) than the next lower whole value. For example, a pH of 10 is ten times more alkaline than a pH of 9.

pH meters are the most accurate type of measurement and are widely used. Pocket-sized meters called testers are small, easy to use for fieldwork and relatively low cost.

A pH meter is considered accurate and in a good condition if the reading difference between the measurement and standard value is ≤ 0.30 pH. It could be that the pH electrode of the meter is not suitable for testing your samples, since most pH electrodes are only designed for general water solutions.

Use filter paper such as coffee filters, or acid-free art paper. Immerse the paper into the cabbage juice indicator you have made. Soak the paper until thoroughly wet. Remove the paper and allow it to dry in a neutral environment free of acids or alkaline condensation.

Natural remedies to restore balance

1. Avoiding harsh soaps and douching. Soaps typically have a high pH, and using them to clean the vaginal area may increase vaginal pH.
2. Taking a probiotic supplement or suppository.
3. Changing tampons regularly.
4. Using barrier protection during sex.

What materials are required?

• pH test paper (1-14 range preferably) (6 strips per student)
• Small paper cups (6 per student)
• Baking Soda (1 teaspoon per student)
• Measuring spoon (teaspoon)
• Marker.
• 1 to 2 ounces of the following liquids are required per student: Distilled water. Window cleaner solution. Toilet bowl cleaner.

Firstly fill up a clean container with test water and make sure the water level is deep enough to cover the litmus paper strips. Secondly, dip one of the test strips into the container of water for a few seconds. Litmus paper will either be red and blue. Red litmus paper turns blue if it is dipped in a basic solution.

You can determine your body’s pH using a simple urine test. For best test accuracy, the test should be performed first thing in the morning. Urine tests measure the level of acid in the body. Optimal pH levels are between 6.5 and 7.5.

Red cabbage juices is the best known edible pH indicator in your kitchen but there are many safe fruits, vegetables and flowers that change color in response to acids and bases such as eggplant, beets, blueberries, cherries, onion, raspberry, grape juice, turmeric, and even tomatoes!

Fruits and fruit juices high in acid

• lemon juice (pH: 2.00–2.60)
• limes (pH: 2.00–2.80)
• blue plums (pH: 2.80–3.40)
• grapes (pH: 2.90–3.82)
• pomegranates (pH: 2.93–3.20)
• grapefruits (pH: 3.00–3.75)
• blueberries (pH: 3.12–3.33)
• pineapples (pH: 3.20–4.00)

Acid-base indicators are weak organic acids. The most important property of an indicator is its pH range, which is dependent on the indicator’s acid strength. An indicator’s pH range is the range of pH values over which the indicator changes colors from its acid form to its base form.

Beets, blackberries, grape juice, plums, turnip skin, and more all act as an edible natural pH indicator. They all have anthocyanin in them which makes the solution change color, but they also differ in that little side groups attached to the main molecule cause the color changes to vary between foods.

Normally, the indicator causes the color of the solution to change depending on the pH. Solutions with a pH value below 7.0 are considered acidic and solutions with pH value above 7.0 are basic (alkaline).

This is measured using the pH scale , which runs from pH 0 to pH 14. Universal indicator has many different colour changes, from red for strongly acidic solutions to dark purple for strongly alkaline solutions. In the middle, neutral pH 7 is indicated by green.

Note: Beetroots, blackberries, plums, turnip skin, and more all act as an edible natural pH indicator. They have anthocyanin in them which makes the solution change color, but they differ when side groups are attached to the main molecule cause the color changes vary between foods.

Beetroot. Another alkaline-forming food is beetroot. There are several health benefits of drinking beetroot juice every day. It cleanses your body and keeps you healthy physically and mentally.
