Types of reactions

1. We lit magnesium on fire which caused a bright uv light and the the magnesium turned into a white powder.

2. When we turned the torch on the flame was green and it gradually changed to blue.

3.When we added a potassium iodide crystal to the hydrogen peroxide it began to turn orange and bubble, it then expanded out of the graduated cylinder and began to steam a small amount and was very hot and smelly.

4. When we put the copper into the silver nitrate it immediately grew black spots on it and the longer we left it, it grew into a mold like substance.

5. When we added a drop of the lead (||) nitrate to the potassium iodide it instantly turned yellow.

6. When we mixed the sodium hydroxide (base) and the sulphuric acid (acid) together they made an acid.
