Place 50cm³ of 2M hydrochloric acid into a calorimeter/200cm³ plastic beaker wrapped in cotton wool/tissue paper. Record its temperature T1.Using a clean measuring cylinder, measure another 50cm³ of 2M sodium hydroxide. Rinse the bulb of the thermometer in distilled water. Determine the temperature of the sodium hydroxide T2.Average T2 andT1 to get the initial temperature of the mixture
T3.
Carefully add all the alkali into the calorimeter/200cm³ plastic beaker wrapped in cotton wool/tissue paper containing the acid. Stir vigorously the mixture with the thermometer.
Determine the highest temperature change to the nearest 0.5^oC T4 as the final temperature of the mixture. Repeat the experiment to complete table 1.
