Question

Which of the following salts will give an aqueous solution having $pH$ of almost 7?

• A. $N{H}_{4}N{O}_3$
• B. $N{H}_{4}Cl$
• C. $CaC{l}_2$
• D. $KCl$

Answer 1

The correct option is D $KCl$

$KCl$ solutions are stable. In aqueous state $KCl$ solutions fully ionize into solvated potassium and chloride ions. So it is neutral with $pH=7$.
