Q. What is the acceptable limit of arsenic in drinking water mg L )?
As per BIS Standards (IS 10500: 2012) the maximum permissible limit of Arsenic in drinking water is 0.01 mg/l (ppm) or 10 µg/L(ppb).
Q. Who limits for potable water?
WHO has prescribed a provisional guideline value of As 10 μg/l in drinking water and according to India standard drinking water specification 1991, the highest desirable limit is 50 μg/l and no relaxation for maximum permissible level.
Q. Why is turbid water not suitable for consumption?
Answer: In drinking water, the higher the turbidity level, the higher the risk that people may develop gastrointestinal diseases. This is especially problematic for immunocompromised people, because contaminants like viruses or bacteria can become attached to the suspended solids.
Q. Which water is not suitable for consumption?
Sea water contains more amount of dissolved salts and hence it is unsuitable for drinking. Sea water is made potable through reverse osmosis process. Sea water is not fit for drinking. Why?
Q. What happens if you drink water with high turbidity?
High turbidity in drinking water can shield bacteria or other organisms so that chlorine cannot disinfect the water as effectively. Some organisms found in water with high turbidity can cause symptoms such as nausea, cramps, and headaches.
Q. What happens if the turbidity is too high?
High turbidity can significantly reduce the aesthetic quality of lakes and streams, having a harmful impact on recreation and tourism. It can increase the cost of water treatment for drinking and food processing.
Q. Is it safe to drink turbid water?
Although turbid water is not inherently unhealthy, it can contain particles that should not be consumed by humans. Some of these problematic particles can include metals or other types of sediment that can negatively affect human health.
Q. Does high turbidity mean low pH?
There is no correlation between pH and turbidity from the results in the third sets of experiments. It indicates that pH is not a direct indicator of turbidity in the treatment of more alkaline solution.
Q. Does dissolved oxygen affect pH?
The amount of dissolved oxygen becomes lower as the water becomes warmer. As the hydrogen ions increase, the water becomes more acidic; as the hydroxyl ions increase, the water becomes more basic. pH is measured on a logarithmic scale of 0 – 14: 7 is neutral; below 7 is acidic; above 7 is basic.
Q. What is the normal range for turbidity?
The WHO (World Health Organization), establishes that the turbidity of drinking water shouldn’t be more than 5 NTU, and should ideally be below 1 NTU.
Q. How is the environment affected by too low or too high pH?
If the pH of water is too high or too low, the aquatic organisms living within it will die. pH can also affect the solubility and toxicity of chemicals and heavy metals in the water ¹². The more sensitive a species, the more affected it is by changes in pH.
Q. What happens if soil pH is too high?
When a plant’s soil pH increases, which is what would happen when its food’s pH is too high, the plant’s ability to absorb certain nutrients is disrupted. As a result, some nutrients cannot be absorbed properly. The soil’s high pH prevents the iron present in the soil from changing into a form the plant can absorb.
Q. Which number is the most alkaline?
A: Alkaline refers to part of the pH scale. This scale is from 0-14, the lower numbers are more acidic while the higher numbers are more alkaline with 7 being neutral. Most alkaline waters have a pH of 8 or 9 while pure water has a neutral pH of 7.
Q. What is the best soil pH?
between 6.0 and 7.0
Q. Can you use vinegar to lower pH in soil?
Using Vinegar on Soil To lower the pH level of soil and make it more acidic, vinegar can be applied by hand or using an irrigation system. For a basic treatment, a cup of vinegar can be mixed with a gallon of water and poured over soil with a watering can.
Q. What is the fastest way to lower pH in soil?
Soil pH can be reduced most effectively by adding elemental sulfur, aluminum sulfate or sulfuric acid. The choice of which material to use depends on how fast you hope the pH will change and the type/size of plant experiencing the deficiency.
