A white precipitate can be obtained by adding dilute sulphuric acid to:(a)Ba(NO₃)₂  solution  (b)KNO₃ solution     (c) AgNO₃ solution   (d)Mg(NO₃)₂ solution

Correct Answer: (c) AgNO3 solution

Explanation: A white precipitate of silver chloride along with sodium nitrate is formed when we add common salt to silver nitrate as it is a precipitation reaction. The equation is given as:

$AgNO_{3} \ ( aq) \ +\ NaCl\ ( aq) \ \rightarrow \ AgCl\ ( s) +\ NaNO_{3} \ ( aq)$
