Acid + Carbonate Reaction

Question 1

what is the word equation for the reaction when carbonates react with acid?

Answer 1

acid + metal carbonate -> salt + water + carbon dioxide

Question 2

observations in an acid + carbonate reaction?

Answer 2

• the carbonate disappears - because it is used up in the reaction
• there is fizzing - this is because a gas (carbon dioxide) is produced

Question 3

what happens if the salt is soluble in an acid + carbonate reaction?

Answer 3

it dissolves into the water to form a salt solution

Question 4

what is the chemical test for carbon dioxide?

Answer 4

limewater -> turns cloudly

• this is because the carbon dioxide reacts with the limewater to make an insoluble white solid
