Some – Use an ionic equation to describe neutralisation.(A/B)

To learn about neutralisation

Acids and alkalis.

Acids contain positively charged hydrogen ions H+. Alkalis contain negatively charged hydroxyl OH- ions. When we mix an acid and an alkali these two combine and produce water. If there are equal number of these ions we get a neutral solution

H+ + OH-H2O
