Testing for Carbon Dioxide Gas
Aim: To shows that carbon dioxide gas is produced when when a metal carbonate reacts with acid.
Equipment: Two boiling tube, delivery tube and bung, Bunsen burner, test tube rack, wooden splint, a bottle of acid, small amount of metal carbonate, test tube tongs, safety glasses.
Method:
1. Light your Bunsen burner.
2. Add a 'pea-sized' amount of the metal carbonate into one of the boiling tubes.

Aim: To carry out a test for the presence of oxygen gas.
Equipment: A pea-sized amount of manganese dioxide, boiling tube, bottle of hydrogen peroxide, safety glasses, wooden splint, Bunsen burner and a test tube rack.
Method:
1. Light your Bunsen burner.
2. Add the manganese dioxide to the boiling tube and place it in your test tube rack.
3. Add 2ml of hydrogen peroxide.
4. Light a splint and let it burn for a while.
5. Blow the splint out and insert the glowing embers into the mouth of the boiling tube.
Today in our Science class we did an experiment about metal and how it reacts to acid.
Equipment:
What is acid rain?
Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic.
What is our Aim?
Our aim will be to observe effects of Acid Rain.
Hypothesis
Petal, Calcium carbonate, Apple, Universal Indicator, Bromothymol Blue.
Method:
In a petri dish place items around the edge. Wet dry ingredients with drop of water. in the middle put a weight boat.
Add a spatula of Sodium sulfate to weight boat, and 5 drops of Sulfuric Acid.
Observation:
The Bromothymol turned yellow, the Universal Indicator turned red, some part of Calcium Carbonate were wet, I'm not sure what happened to the petal and but it kinda turned into a darker colour.
