Scientists use the pH scale to measure how acidic or alkaline liquids are. Lemons taste sharp because they’re acidic - about pH 2. Water is neutral and is pH 7. Very few liquids that are alkaline are safe to drink. Sea water is an example of an alkali and is about pH 8 and many household cleaning products range from pH 8 –14. When a substance called Universal Indicator is added to liquids, a different colour is generated depending on their pH. Solve the addition sums and use the pH scale as a guide to colour the scientists. With a responsible adult, you can try out their recipe too!

Scientists use the pH scale to measure how acidic or alkaline liquids are. Lemons taste sharp because they’re acidic - about pH 2. Water is
neutral and is pH 7. Very few liquids that are alkaline are safe to drink. Sea water is an example of an alkali and is about pH 8 and
many household cleaning products range from pH 8 –14.
When a substance called Universal Indicator is added to liquids, a different colour is generated depending on their pH. Solve the
addition sums and use the pH scale as a guide to colour the scientists. With a responsible adult, you can try out their recipe too!
