Question: Equal volume of 1 M HCl and 1 M H<sub>2</sub>SO<sub>4</sub> are neutralized by dilute NaOH solution ...
Equal volume of 1 M HCl and 1 M H2SO4 are neutralized by dilute NaOH solution and x and y kcal of heat are liberated respectively. Which of the following is true ?
A
x = y
B
x =0.5 y
C
x = 0.4 y
D
None of these
Answer
x =0.5 y
Explanation
Solution
1 M H2SO4 = 2 equivalent H2SO4
1 M Hcl = 1 equivalent HCl
Thus, for equal volume of two acids to be neutralized separately with NaOH, heat evolved will be twice in case of H2SO4 to that of HCl.
