Acid Metal SALT Hydrogen Acid BASE SALT Water

Acid + Metal SALT + Hydrogen Acid + BASE SALT + Water Acid + Metal carbonate SALT + Water + CO 2

A BASE is a metal oxide or metal hydroxide • for example, gold oxide, magnesium hydroxide, sodium hydroxide • A base that dissolves in water is called an ALKALI A SALT is an ionic compound • Formed from a METAL and a NON-METAL From the metal, base or carbonate From the acid

Metal examples Acid + Metal SALT + Hydrogen Calcium + hydrochloric acid _______ Calcium chloride + ____ Hydrogen Iron + hydrochloric acid _______ + ____ Iron chloride Hydrogen _____ Titanium + hydrochloric acid Titanium chloride + Hydrogen

Carbonate examples Acid + Metal carbonate SALT + water + CO 2 Water + _______ CO 2 Magnesium chloride + ______ Magnesium carbonate + hydrochloric acid _______ Sodium chloride Sodium carbonate + hydrochloric acid _______ CO 2 Water + _______ + ______ Lithium carbonate + hydrochloric acid Lithium chloride + _______ Water + CO 2 _______

Base examples Acid + Base SALT + water Magnesium chloride Magnesium oxide + hydrochloric acid ________ Sodium chloride Sodium hydroxide + hydrochloric acid _______ Water + ______ Lithium hydroxide + hydrochloric acid Lithium chloride + water _______ (Or lithium oxide)

So far we have done reactions with hydrochloric acid – this forms salts called CHLORIDES SULPHURIC ACID forms salts called SULPHATES NITRIC ACID forms salts called NITRATES Magnesium sulphate + _______ Hydrogen Magnesium + Sulphuric acid ________ Sodium sulphate + _______ Water CO 2 Sodium carbonate + Sulphuric acid _______ + _____ Calcium nitrate Water Calcium oxide + Nitric acid _______ + _______
