WebThe reaction with concentrated acids is highly exothermic (releasing heat). The H2 gas that is produced as a result of the reaction might get ignited by the heat, and burn violently. Concentrated acid reactions usually cause explosions, and might lead to someone getting hurt. Also, we have to be really carefulwhile handling the acid.
