Question

A salt is dissolved in water and the pH of this salt solution is measured with a universal indicator paper. If the pH of solution is less than 7, the salt is most likely to be :

(a) $C{H}_{3}COONa$

(b) $N{a}_{2}C{O}_3$

(c) $KCl$

(d) $N{H}_{4}Cl$

Answer 1

$N{H}_{4}Cl$ will give an acidic solution because it is made up of a strong acid and weak base.
