Hello, guys today blogging about a science experiment that we did this week, I was with my friend Khush while doing the experiment so we have to have like 5 test tubes that we need to use and like there is a letter from A to D. We have to put an iron nail in each test tubes and put like salt but not in the same test tube.
Corrosion:
When metals are exposed to the environment they can deteriorate, or break down. Scientists call this process corrosion, Rust is the term used to describe the corrosion of iron.
Aim: To investigate the factors that cause rusting in iron.
Equiptment: Four test tubes, test tube rack, a bung, four iron nails, boiled water, tap water, salty water, cooking oil, calcium chloride.
Method:
1. Label four test tubes A - D and place them in a test tube rack.
2. Test tube contents:
A = Iron nail and tap water
B = Iron nail and salty water.
C = Iron nail, boiled water. oil
D = Iron nail and calcium chlorides. Sealed with a bung.
3. Leave the test tubes undisturbed for at least three days.
