Question

Under identical conditions, how many millilitres of 1 M-KOH and 2 M-H2SO4 solutions are required to produce a resulting volume of 100 ml with the highest rise in temperature?

Options

A.80, 20
B.20, 80
C.60, 40
D.50, 50

Solution

For maximum rise in temperature, both should react completely.

$V \times 1 = (100 - V) \times 2 \times 2 \Rightarrow V = 80 = V_{KOH}$
