Junior year, Chemistry 2. We were talking about ionic compounds and our teacher reminded us of a rule that when a compound ends with “-ite”, the compound then ends with “-ous” when it becomes acid. Like hypochlorite becomes hypochlorous acid. Also, if a compound ends with “-ate” it will end with “-ic” when it becomes acid. Like, perchlorate becomes perchloric acid.
At that time, our teacher asked us the acid name for hydrogen sulfite, and we replied “hydrosulfous acid” which made our teacher say, “What?!”, and we just laughed.. Then, she asked about hydrogen sulfate. We replied “hydrosulfic acid”. Laughters again. She asked about hydrogen phosphite and hydrogen phosphate to which we answered with, “hydrophosphous acid” and “hydrophosphic acid”, respectively. And we did that on purpose.
That day still puts a smile on a my face.
