What is neutralisation?
The reaction of acids with bases
What happens to an acid when neutralisation occurs?
The hydrogen ions are removed from the acid and are replaced with metal or ammonium ions and a salt is formed

What exactly happens in a reaction between an acid and an alkali?
Te hydrogen and hydroxide ions form water
What exactly happens in a reaction between acid and metal oxides?
The hydrogen ions and the oxide ions form water
What exactly happens in a reaction between an acid and a metal carbonate?
The hydrogen ions and the carbonate ions for water and carbon dioxide
What exactly happens in a reaction between an acid and a metal?
The hydrogen ions from the acid are replaced with metal ions and the hydrogen ions form molecules of hydrogen gas
What is he test for hydrogen gas?
It burns with a pop
Name 2 examples of every day neutralisation
Treatment of acid indigestion
Using lime to reduce acidity in soil and lochs
What produces acid rain?
Sulphur dioxide, produced by the burning o fossil fuels, and nitrogen dioxide, produced by the sparking of air in a car engine, dissolve in water in the atmosphere to produce acid rain
