## Question

Two acids H_{2}SO_{4} and H_{3}PO_{4} are neutralized separately by the same amount of an alkali when sulphate and dihydrogen orthophosphate are formed respectively. Find the ratio of the masses of H_{2}SO_{4} and

### Solution

1 : 2

1 g eq. of alkali (NaOH) will neutralize 1 g eq. of H_{2}SO_{4} and 1 g eq. of H_{3}PO_{4}. For the given neutralization reactions,

Hence, the ratio of masses of H_{2}SO_{4} and H_{3}PO_{4} = 49 : 98 = 1 : 2
