The chemist studied the properties of bismuthic compounds for their potential applications.
Bismuthic → It is formed from "bismuth" (from German "Wismut", meaning a heavy metal) and the suffix "-ic" (meaning pertaining to or relating to). The word "bismuthic" refers to something that is related to or derived from bismuth, a chemical element.
Think of 'bismuth' as the heavy metal and '-ic' meaning related to it — so bismuthic means related to the heavy metal bismuth.
