For today's Science lesson, we went through the acids and alkalis worksheet which we had completed before this lesson.
I learnt that:
- Baking powder is known as sodium carbonate
- When you have gastric pains, acids are being produced in your body
- Calcium hydroxide is used to neutralise the acids in the water
- Ammonium is used to describe salt while ammonia is used to describe gas
- Sulfuric acid is used to remove rust from iron and steel objects in industry
- Nitric acid is used in making explosive
- Potassium hydroxide is an ingredient in paint removers
- Limewater is known as calcium hydroxide
