acid + metal carbonate → salt + water + carbon dioxide
What is the general word equation for the reaction between an acid and a metal?
acid + metal → salt + hydrogen
What are the steps for obtaining soluble salt crystals from an acid-base reaction?
Place dilute acid in a beaker and gently heat it
Add the solid base bit by bit until it stops reacting, which means it’s in excess
Isolate the salt solution by filtering out the excess solid base using filter paper and funnel
Heat the salt solution gently in a water bath until crystals start to form
Let the solution cool further, which will cause more crystals to precipitate
Filter out the soluble salt crystals using filter paper and a funnel
