When 400 mL of 0.2 M H2SO4 solution is mixed with 600 mL of 0.1 M NaOH solution, the increase in temperature of the final solution is __________ \(\times\) 10\(-\)2 K. (Round off to the nearest integer).
[Use : H+ (aq) + OH\(-\) (aq) \(\to\) H2O : \(\Delta\)\(\gamma\)H = \(-\)57.1 kJ mol\(-\)1]
Specific heat of H2O = 4.18 J K\(-\)1 g\(-\)1
density of H2O = 1.0 g cm\(-\)3
Assume no change in volume of solution on mixing.
