Hope it helps u !!

Answer 2

Solution:

in first question: option 1 is correct.

in second question:  option 1 is correct.

Explanation:

For first question:

Nitric acid is added in the limit test of chloride to make solution acidic and helps silver chloride precipitate to make solution turbid at the end of process.

For second question:

Limit test of sulphate is based on the reaction of soluble sulphate with barium chloride in presence of dilute hydrochloric acid to form barium sulphate which appears as solid particles(turbidity) in the solution
