# Student studying acidity of juices did a taste test and determined that the orange juice was the sweetest juice the lemon and and lime juices were the sourest. Based on this information, which is the best inference the student could make about acidity?

Not so long ago, approx. 150 years, a chemist would report on the taste of a new compound he synthesized (I write $\text{he}$ because I hope a woman wouldn't be so stupid!). Most of the things we eat that taste good, are in fact slightly acidic. See this older answer.
