Year5 Science Acid Test

Date: 20th Sep 2022 @ 4:58pm

Today the pupils in Year 5 have been learning about acids and alkalis.  First of all we used bicarbonate of soda to neutralise an acid (white vinegar). When this happened the liquid started fizzing and bubbles of carbon dioxide were created. This tells us that a chemical reaction took place. Pupils then conducted an experiement to test the pH level of several everyday items, such as cola, vinegar and lemon juice. The pH level tells you if the substance is an acid or an alkali.
