Acids and Alkalis Worksheet

Headline: Acids and Alkalis Worksheet.


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
