In order to determine the molar heat of neutralization of potassium hydroxide, 200cm3 of 1M Hydrochloric acid and 200cm3 Of IM Potassium hydroxide both at the same initial temperature were mixed and stirred continuously with a thermometer. The temperature of the resulting solution was recorded after every 30 seconds until the highest temperature of the solution was attained. Thereafter, the temperature of the solution was recorded for a further two minutes.
