0cm3 of acid were mixed with 60cm3 of alkali in an insulated container. The average temperature of the two solutions before they

were mixed was 19.5°C. The temperature after mixing was 27.5°C. Was this an exothermic or an endothermic reaction?

Answer: Endothermic reaction.

Explanation: An endothermic reaction is any chemical reaction that absorbs heat from its environment. In this reaction, the temperature of the mixture raised from 19.5°C to 27.5°C, which means there was an increase of heat, ergo, it is an <u>endothermic</u> reaction.
