Acids and Alkalis in Year 8

26th January 2023

Our Year 8 students are currently studying Acids and Alkalis and they created their own indicator solution using water and red onion. They used this solution to then test different chemicals to determine whether they were an acid, alkali, or neutral.

They cut up red onion and then boiled it in water using a Bunsen burner, after allowing the solution to cool they used the filtration techniques they learned earlier this year to remove all onion pieces from the solution and they then used the filtrate to test different lab chemicals.

They are enjoying their time in the lab so far and looking forward to more practical’s!
