Under the same conditions, how many `mL` of `1M KOH` and `0.5M H_(2)SO_(4)`solutions, respectively, when mixed to form a total volume of `100mL`, produces the highest rise in temperature?

A

67,33

B

33,67

C

40,60

D

50,50

Text Solution

Verified by Experts

The correct Answer is:
D
`1 M KOH = 1N KOH`
`0.5 M H_(2)SO_(4) =2xx0.5 =1 N H_(2)SO_(4)` For maximum rise in temperature, there should be complete neutralisation. Therefore, `KOH and H_(2)SO_(4)` should be mixed in the ratio of 1:1 i.e. 50:50 (since normality is same).
