Neutralisation Equations

• Acid + Metal Hydroxide = Salt + water
• Acid + Metal carbonate = Salt + water + Carbon dioxide
• Acid + metal = Salt + Hydrogen

Naming the salt

• The name of the salt is made up of 2 words, a first and last name.
• The first is the metal in the reaction.
• The last depends on the type of acid used.

Reaction of group 1 metals with water, oxygen and chlorine.

• Metal + water = Metal hydroxide + hydrogen
• Metal + oxygen = Metal oxide
• Metal + chlorine = Metal chloride
• 

Balancing equation

NaOH + H2SO4 ---> Na2SO4+H20

• Put a box round each individual chemical formulas
• Make a table like below
• See how many atoms are in the equation before and after reaction
• See how many you neeed to bring before to after
• Solve the equation
