Answer to Question #193881 in General Chemistry for Zariyah

Question

Following the neutralization of a solution of dilute potassium hydroxide (KOH(aq)) with a solution of 0.50 mol/L hydrochloric acid (HCl(aq)), given :

Before neutralization

KOH(aq) with volume of 100 ml and temperature of 22 °C

HCl(aq) 0.50 mol/L and with volume of 50ml and temperature of 22.2°C

After neutralization

Mixture is now 150 ml as volume and 24.5 °C as temperature.

What is the value of the molar heat (ΔH) of neutralization of hydrochloric acid?

Answer 1

Molar heat (ΔH) of neutralization=$-57.2kJM$
