Sulfuric acid + potassium hydroxide -> potassium sulfate + water
H2SO4 + 2KOH -> K2SO4 + 2H2O
Nitric acid + sodium hydroxide -> sodium nitrate + water
HNO3 + NaOH -> NaNO3 + H2O
To work out the formula of an ionic compound, you need to balance the charges of the positive and negative ions so the overall charge of a compound is neutral
Acids and metal carbonates produce carbon dioxide
Metal carbonates are also bases. They react with acids to produce a salt, water and carbon dioxide
