Q1: In which of the following case of mixing of a strong acid with strong base (each of 1N concentration), temperature increase will be the highest ?

ANS:A - 30 c.c acid and 30 c.c base.

When a strong acid reacts with a strong base, it typically undergoes a highly exothermic reaction, releasing heat. The temperature increase will be the highest when the volumes of the acid and base are in the most significant proportion, leading to the most extensive reaction. Considering the given options, the highest temperature increase will occur when the volumes of acid and base are equal. This is because in this case, the reaction will occur most extensively, leading to the most significant release of heat. So, the option where the volumes of acid and base are equal, 30 c.c acid and 30 c.c base, will result in the highest temperature increase.
