Lesson 1 of 2
Acid behaviour with metals and carbonates
Diluted in water, the carboxylic acids behave like other acids you have met. Metals hand over a salt plus hydrogen, carbonates hand over a salt plus water plus carbon dioxide, and every salt name ends in anoate. This lesson pins the two patterns down.
What you know already
From Carboxylic Acids you already know the -COOH group that ends every member of the family. This note watches that group behave like any other acid: metals and carbonates go in, and salts with a telling name ending come out.
Key points of understanding
- Aqueous solutions of carboxylic acids react with metals to give a salt and hydrogen.
- They react with metal carbonates to give a salt, water and carbon dioxide.
- Salts made from these acids all end in anoate.
- Methanoic acid therefore forms methanoate salts and ethanoic acid forms ethanoate salts.
- The reaction with a metal produces hydrogen gas alongside the metal salt.
