A 50% solution of sulphuric acid is subjected to electrolyte oxidation and the product is hydrolysed.

What is the density of solution of sulphuric acid used as an electrolyte in lead accumulator ?

When the same quantity of electricity is passed through the solution of different electrolytes in series, the amount of product obtained is proportional to their

The oxidation state of sulphur in sulphoxylic acids is

Hot concentrated sulphuric acid is a moderately strong oxidizing agent. Which of the following reactions does NOT show oxidizing behaviour ?

(a). Assertion (A) is true, Reason (R) is also true, Reason (R) is the correct explanation for assertion (A). (b). Assertion (A) is true, Reason (R) is true, Reason (R) is not the correct explanation for Assertion (A). (c). Assertion (A) is true, Reason (R) is false. (d). Assertion (A) is false, Reason (R) is true. Q. Assertion (A): to a solution of potassium chromate, if a strong acid is added, it changes its colour from yellow to orange. Reason (R): The colour change is due to the change in oxidation state of potassium chromate.

For the estimation of nitrogen, 1.4 g of an organic compound was digested by Kjeldahl's method and the evolved ammonia was absorbed in 60 mL of M//10 sulphuric acid. The unreacted acid required 20 mL of M//10 sodium hydroxide for complete neutralisation. The percentage of nitrogen in the compound is

When SO_2 is passed an acidified potassium dichromate solution, the oxidation state of sulphur is changed from
