fill in the blank
In water, carboxylic acids are weak acids
Why do carboxyllic acids have a higher pH than strong acids?
They have a lower concentration of H+ ions than strong acids
How do carboxylic acids react with metal carbonates?
Carboxylic acid + metal carbonate → Salt + carbon dioxide + water
What is the word equation for the reaction between methanoic acid and a metal carbonate?
Methanoic acid + metal carbonate → Metal methanoate + carbon dioxide + water
What is the word equation for the reaction between ethanoic acid and a metal carbonate?
Ethanoic acid + metal carbonate → Metal ethanoate + carbon dioxide + water
What is the word equation for the reaction between propanoic acid and a metal carbonate?
Propanoic acid + metal carbonate → metal propanoate + carbon dioxide + water
What is the word equation for the reaction between butanoic acid and a metal carbonate?
