Test the basicity of toothpastes and give context to neutralisation reactions

Provide real-world relevance to neutralisation reactions by investigating whether different toothpastes are neutral, alkaline or basic. Download the equipment list, method, results table and questions (with answers) and carry out the practical.

The answers provided are based on the toothpaste brands used here but other toothpastes can, of course, be tested. Why not try testing different indigestion tablets or other everyday products too?
