In our today's session we decided to test the following hypothesis: indigestion remedies bought from a chemist are better than using baking powder or bicarbonate of soda.
We used the litmus paper and pH probes to check the pH of the hydrochloric acid and see if neutralization occurred.
We concluded that Rennie was the best at neutralizing the acid.
Today's session was special as the co-ordinator from our partner school, Mrs Grażyna Ochwat, paid us a visit.
