Question

1. explain why it is important to exercise extreme care when heating the asa sample with 1m naoh solution.

Explanation:

ASA (acetyl - salicylic acid) can react with NaOH. Heating can accelerate the reaction rate. Excessive heating may cause side - reactions like decomposition of ASA or over - reaction, altering the sample composition. Also, heating a strong base solution can cause splashing which is a safety hazard.

Answer:

Heating can cause side - reactions, alter sample composition, and pose a safety risk due to possible splashing.
