Add some mildly acid Iodide to the hypo chlorite solution.
Titrate the formed Iodine-Iodide complex (I3-) with disodium thiosulfate until the starch (added at almost the end) color (black-blue with Iodine-Iodide complex) is disappeared.
- ClO- + Cl- + 2 H+ --> 'Cl2'available + H2O
- 'Cl2'available + 3 I- --> 2 Cl- + I3-
- I3- + 2 S2O32- --> 3 I- + S4O62-

How do you calculate available chlorine?
Available chlorine is calculated by taking the total chlorine level and subtracting the combined chlorine level. This gives you the amount of chlorine available to sanitize the water. It's important to regularly test and maintain the chlorine levels in pools and spas for proper disinfection.
What is free chlorine in a pool?
Free Chlorine is the Chlorine which is free to do its work in the pool, as opposed to Combined Chlorine which is chlorine that has combined with contaminants and is tied up and ineffective as a sanitizer in the pool. Sometimes you will see it abbreviated as FAC, which stands for Free Available Chlorine.
Can you swim in pool hat has a normal chlorine level but the free chlorine level is high?
There is 3 measurements of chlorine in a pool or spa. Total chlorine, combined chlorine, and free available chlorine. Free available chlorine is the good chlorine that is active in the pool killings germs and algae. Combined chlorine is chlorine is basically chlorine that was once active but has killed germs or bacteria and is now inactive in the pool. Total chlorine is free available and combined chlorine added together. If your combined chlorine is higher than free available chlorine then the water needs to be shocked to eliminate the combined chlorine. But be careful here. If you don't reach what's called break point you will only add to the combined chlorine. There are products on the market which will only remove combined chlorine without effecting your free available chlorine if you are unsure about reaching breakpoint. Hope this helps.
What is meant by available chlorine in bleaching powder?
Usually it relates to hypochlorites content in the product. Available chlorine is the quantity of chlorine that can hypothetically be produced by reaction of bleaching powder with hydrochloric acid. Greater the available chlorine is - greater oxidation ability the bleaching powder has. For example, available chlorine 5% means that fixed amount of something can be oxidized by (100/5)X=20X grams of bleaching powder and the same can be done with only X grams of pure chlorine.
Does it matter what brand of chlorine you use as long as it contains the same available chlorine?
As long as the chlorine product contains the same amount of available chlorine, the brand shouldn't make a significant difference in terms of effectiveness. However, quality control and additional ingredients in different brands may impact handling, dissolving speed, or other factors, so it's essential to follow the manufacturer's instructions for the specific product you are using.

What is the role of copper sulphate in estimation of copper by iodometry?
Copper sulfate is used to keep the copper ions in solution so that they can be titrated accurately. Iodometry involves the use of iodine to oxidize copper ions to cupric ions, which are then titrated with a standardized solution of thiosulfate to determine the amount of copper present. Copper sulfate ensures the copper ions remain in solution throughout the titration process.
What is the percentage of available chlorine in sodium hypochlorite?
Sodium hypochlorite typically contains 10-12% available chlorine.
What are the uses of iodometry?
Iodometry is used to determine the concentration of oxidizing agents by titrating them with a solution containing iodide ions. It is commonly used in analyzing chlorine in water treatment, measuring the concentration of hydrogen peroxide, and determining the ascorbic acid content in vitamin C tablets.
How can you change combined chlorine to free available chlorine?
To change combined chlorine to free available chlorine, you can perform a shock treatment by adding a chlorine shock product to the pool water. This will help break down the combined chlorine compounds and convert them back into free available chlorine. Make sure to follow the product instructions carefully and retest the water after treatment to ensure proper chlorine levels.

What is available chlorine?
Available chlorine refers to the active chlorine present in a disinfectant or bleach that is capable of performing the desired sanitizing or oxidizing functions. It includes both free chlorine (hypochlorous acid and hypochlorite ion) and combined chlorine (chloramines) in a water solution. Available chlorine levels are crucial in ensuring effective water treatment and sanitation processes.

What is the percentage of available chlorine bleaching powder?
Typically, the percentage of available chlorine in bleaching powder ranges from 30% to 35%. This is important to consider when using it for disinfection or bleaching purposes to ensure proper dilution and effectiveness.
