Question

Test to determine whether a substance is an solid acid?

Answer 1

activity Mix a sample of the liquid with a known acid. Acids and bases are well known for neutralizing each other on contact. This neutralization reaction can be recognized because it releases heat and gas, which causes the two reactants to fizz. Choose a well known, safe acid to do this reaction. Put a sample of your liquid into a bowl or dish. Add your acid with a dropper. If you see fizz forming in the bowl, your liquid is most likely a base.[1]
Choose a dilute acid such as vinegar. Do not use strong acids like hydrochloric acid or nitric acid.
