Acids and AlkalisWhen an acid neutralises an alkali two

chemicals are made:Salt Water

Sulfuric acid + sodium hydroxide sodium sulfate + water

Acid Alkali salt

Nitric acid + potassium hydroxide potassium nitrate + water

Acid Alkali salt

SaltsThe name of the salt comes from the name of

the acid:Hydrochloric acid makes chloride saltsSulfuric acid makes sulfate saltsNitric acid makes nitrate salts.
