Therefore, the mass in grams of a single chlorine atom and of single molecule of O2 are 5.89× 10−23 g/atom and 5.31 × 10−23 g/atom.

Explain. Answer: The reason for the atomic mass of chlorine taken as 35.5u and not as 35u because of the presence of isotopes. Consider a chlorine atom, it will have 17 protons and hs two isotopes they are chlorine – 35 and chlorine – 37.

When chlorine (in any form) is added to water, a weak acid called Hypochlorous acid is produced. It is this acid, not the chlorine, which gives water its ability to oxidize and disinfect. Proper chlorination and filtration give pool water its clear, sparkling appearance. Chlorine exists as a solid, a liquid and a gas.

Represented by the chemical symbol “Cl,” chlorine is number 17 on the Periodic Table of the Elements, indicating each atom of chlorine contains 17 protons and 17 electrons.

When chlorine enters the body as a result of breathing, swallowing, or skin contact, it reacts with water to produce acids. The acids are corrosive and damage cells in the body on contact.

Chlorine is commonly used as an antiseptic and is used to make drinking water safe and to treat swimming pools. Large amounts of chlorine are used in many industrial processes, such as in the production of paper products, plastics, dyes, textiles, medicines, antiseptics, insecticides, solvents and paints.

So the short answer is, no, it is not because chlorine is green. In fact, it is because the copper compounds, which are also in pools, are greenish. When that reacts with the chlorine it can bind to hair causing it to look green.

A purple shampoo won’t work for green pool hair simply because purple does not counterbalance green. Remember that basic color chart from elementary school? Well, this is the secret all hairstylists use to perform color neutralization and tone corrections. Colors on the opposite end cancel each other out.

Although chlorine often gets the blame for turning hair green after swimming, it’s actually copper and other hard metals that do the dirty work; chlorine is just along for the ride. Hair, being naturally porous—that’s how we’re able to color our hair, after all—catches the oxidized metals and turns a greenish tint.

So make sure you’re putting enough chlorine in your water to keep it clear! Too little of CYA and the chlorine burns off pretty quickly which can lead to a green pool. However, too much of it and it basically turns into handcuffs for chlorine and not allow it to work properly in sanitizing your water.

Having too much chlorine in your pool water can be dangerous. Exposure to high levels of chlorine can cause lung irritation, skin and eye damage, and provoke asthma. Not only is it bad for your health, but it can be bad for your pool due to the increase in chlorine.

This is because when the pH gets too low, metal parts (especially copper) will corrode into the water, forming a copper solution. Copper then comes out of the solution when oxidized by chlorine, causing a green color in your pool water and parts.

An excessive amount of pool chemicals can cause your water to be cloudy. That includes: high pH, high alkalinity, high chlorine or other sanitizers, and high calcium hardness.

Although, if you overdo the shock treatment, you risk getting green hair from chlorine due to the excess chlorine oxidizing the copper in the water. You can execute a shock treatment with a few different types of pool shock, just be mindful of how much you’re using.

If your pool is still green after 24 hours, there may be too much of the wrong chemicals, for example an excess of phosphate or cyanuric acid (“stabilizer”). It will take a while for the cloudiness to go away. For a sand filter, it will take a week or more.

How to Fix a Green Pool Fast

1. Vacuum Your Pool to Waste.
2. Brush the Pool Walls and Floor.
3. Test The Water For pH and Alkalinity.
4. Shock Your Pool with Chlorine to Kill Algae.
5. Run, Filter, Run!
6. Test, Balance, and Test Again.

A faster draining is preferred, to allow you to hose off the walls while it drains, to prevent dried on dead algae from baking in the sun. Use enough discharge and direct the water far enough away so that it’s not coming to rest under the pool.

How Do I Get Rid of Algae In My Pool FAST?

1. Vacuum Your Pool Manually. Automatic or robotic pool cleaners aren’t well suited to cleaning algae.
2. Brush Your Pool Walls and Floor.
3. Test and Balance the Water.
4. Shock Your Swimming Pool.
5. Filter Out The Pool Algae.
6. Test Your Pool Water Again.
7. Clean Your Pool Filter.

You often find this menacing algae growing roots on your pool walls, leaving black dots that are sure to ruin your pool day. Bicarbonate, the active ingredient in baking soda, is an effective spot treatment to help kill the algae and loosen it from the wall.

In a swimming pool or spa, algae are those green, brown, yellow, black, or pinkish slime that resemble fur growing on the steps and in corners — places where circulation may not be optimum.
