Secondary 3: Acid reaction worksheet answers

Students, please get back to me if you do not understand the mistakes that you have made in this paper.

1) potassium hydroxide reacting with nitric acid

word equation
potassium hydroxide + nitric acid -> potassium nitrate + water

Chemical equation
KOH + HNO3 -> KNO3 + H2O


2)magnesium carbonate reacting with sulfuric acid

word equation
magnesium carbonate + sulfuric acid -> magnesium sulfate + water + carbon dioxide

Chemical equation
MgCO3 + H2SO4 -> MgSO4 + H2O + CO2

3)sodium carbonate reacting with hydrochloric acid

word equation
sodium carbonate + hydrochloric acid -> sodium chloride + water + carbon dioxide

Chemical equation
Na2CO3 + 2HCl -> 2NaCl + H2O + CO2

4) lithium hydroxide reacting with sulfuric acid

word equation
lithium hydroxide + sulfuric acid -> lithium sulfate + water

Chemical equation
2LiOH + H2SO4 -> Li2SO4 + 2H2O

5)calcium reacting with carbonic acid

word equation
calcium + carbonic acid -> calcium carbonate + hydrogen

Chemical equation
Ca + H2CO3 -> CaCO3 + H2
