Text Solution

AI Generated Solution

To find the percentage of chlorine in a good sample of bleaching powder (calcium hypochlorite, Ca(ClO)2), we can follow these steps: ### Step 1: Determine the molecular formula of bleaching powder The molecular formula of bleaching powder is Ca(ClO)2. This means that it contains one calcium (Ca) atom, two chlorine (Cl) atoms, and two oxygen (O) atoms. ### Step 2: Calculate the molar mass of bleaching powder To calculate the molar mass, we need to sum the atomic masses of all the atoms in the formula. ...

What is the maximum percentage of available chlorine in a sample of bleaching powder ?

The percentage of available chlorine in a commercial sampleof bleaching powder is

Calculate the percentage of available chlorine in a sample of 3.55g of bleaching powder which was dissolved in 100mL of water. 25mL of this solution, on treatment with KI and dilute acid, required 20 mL of 0.125 N sodium thiosulphate solution.

0.71 g of a sample of bleaching powder (CaOCl_2) is dissolved in 100 " mL of " water. 50 " mL of " this solution is titrated with KI solution. The I_2 so liberated required 10 mL 0.1 M Na_2S_2O_3 (hypo) solution in acidic medium for complete neutralisation. Calculate the percentage of available Cl_2 from the sample of bleaching power.

Bleaching power is a mixed salt of hydrochloric acid and hypochlorious acid. It has the formula, CaOCI_(2).H_(2)O . It is manuafactured by the action of chlorine on dry slaked lime at 40^(@)C . There is also a view that bleaching power is a mixture [Ca(OCI)_(2)+CaCI_(2).Ca(OH)_(2).H_(2)O] . The amount of chlorine obtained form a sample of bleching power by the treatement with excess of dilute acids or CO_(2) is called a available chlorine. A good sample of bleaching power constains 35-38% of available chlorine. On long standing, it undergoes auto-oxidation and the amount of acvailable chlorine decreases. The estimation of available chlorine is done volumetrically by (a) iodometric method or by (b) aresenite method. In textile industry, the cotton cloth is mainly bleached with the help of bleaching power. Maximum percentage og available chlorine on the basis of CaOCI_(2).H_(2)O formula is
