Question

When 300 ml of 0.2 M H2A (diprotic strong acid) solution is mixed with 700 ml of 0.1 M KOH solution, the increase in temperature of the final solution is_______ × 10^-3 K. [Given H+(aq) + OH-(aq) → H2O, ΔrH = -13.5 K cal mol^-1] Specific heat of water = 4.2 cal K^-1 g^-1 Density of water = 1 g cm^-3 Assume there is no change in volume of solution on mixing.
