Wonderful Nail Rust Experiment
We put them all into little paper cups of water.
Nail rust experiment. I also think the color of the water will change to the rusty color. This science experiment is all about controlling variables to explore which material will rust an iron nail first. In my expirement I looked at how nails rust while they are soaked in three different types of waters.
And let them sit for a week. Half fill two test tubes with water Put an iron nail in one test tube and label it A and a steel nail in another tube label it B Put an iron nail in a dry test tube and label it C and plug with a small piece of cotton wool on which a few pieces of calcium chloride are placed. At the end of the expirement the nail soaked in the tap water rusted the most the fridge filtered water nail the second most and the zero water nail the least.
For the seiries of Dry wrap a small amount of calcium chloride with a piace of tissue and then put the tissue into the mouth of the testtubes. We got nails screws paper clips staples bobby pins brads etc. A Year 11 chemistry experiment which involves the reaction of nails in different types of liquid.
Even if you dont want to stud. This document is 30 Exchange Credits. How to Do the Rust Oxidation Experiment.
Calcium chloride absorbs water in the right-hand test tube Salt dissolved in water does not. I think it will take one week for the iron to rust in the salt water. If it is tap water it has to have something else in it or the seawater would rust it faster.
The independent variable of this experiment. One in tap water one in fridge filtered water and one in zero water. This experiment is a component of the Year 11 Chemistry course and was assigned as a Practical Assessment Task.
