I like these images - as well as your high-placing entry. Chemistry is / was a passion for me when growing up and through university. I did have to look up mandelic acid. For the dunderheads like myself, you might add the Wikipedia link or information to this substance:
From Wikipedia: Mandelic acid was discovered while heating amygdalin, an extract of bitter almonds, with diluted hydrochloric acid. It was first reported in 1909 by J. W. Walker and V. K. Krieble. The name is derived from the German "Mandel" for "almond". |
