Equal volumes of molar hydrochloric acid...

Equal volumes of molar hydrochloric acid and sulphuric acid are neutralized by dil. `NaOH` solution and `x` Kcal and `y` Kcal of heat are liberated respectively. Which of the following is true?

A

`x=y`

B

`x=(1)/(2)y`

C

`x=2y`

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
B
`HCl + NaOH to NaCl + H_(2)O + x` kcal
`H_(2)SO_(4) + 2NaOH to Na_(2)SO_(4) + 2H_(2)O + y ` kcal
1 molar HCl = 1 g-equivalent of `H_(2)SO_(4)`
so, `y=2x implies x=(1)/(2)y`
