$(a)$ $A$ salt is produced by the reaction between an acid and a base. Identify the acid and the base from which the following salts have been formed:
$(i)$ $Na_{2}SO_{4}$
$(ii)$ $NH_{4}Cl$
$(iii)$ $KNO_{3}$
$(iv)$ $NaCl$
$(i)$ $Na_{2}SO_{4}$
$(ii)$ $NH_{4}Cl$
$(iii)$ $KNO_{3}$
$(iv)$ $NaCl$
$A$ salt is formed by the neutralization reaction between an acid and a base. The cation of the salt comes from the base,and the anion comes from the acid.
| Salt | Acid and Base |
|---|---|
| $(i)$ $Na_{2}SO_{4}$ | Acid: $H_{2}SO_{4}$,Base: $NaOH$ |
| $(ii)$ $NH_{4}Cl$ | Acid: $HCl$,Base: $NH_{4}OH$ |
| $(iii)$ $KNO_{3}$ | Acid: $HNO_{3}$,Base: $KOH$ |
| $(iv)$ $NaCl$ | Acid: $HCl$,Base: $NaOH$ |
