What is Acid Rain?
- When fossil fuel is such as coal, oil and natural gas are burned oxides of carbon, sulfur and nitrogen escape into the air. These molecules dissolve in the water in the clouds and make the water more acidic than normal. When this happen it is called 'acid rain'.
How to make Acid Rain:
Equipment: 3 drops of universal indicator, 3 drops of bromothynol blue, baby flower petal, calcium carbonate, apple, weigh boat
Method:
1. You need a petri dish, prepare your equipment and make them moist by adding water into them.
2. Put your equipment carefully to the petri dish and do not let them touch each other.
3. Put your weigh boat in the middle.
4. Lastly, put some acid on the weigh boat and quickly close the lid.
5. Wait for your experiment.
Observations:
According to my observations, the universal indicator changed first, it was green before and it turn into red when the acid was put on the weigh boat. The bromothynol blue was blue before and it turned to blue to green, it has the same process as the universal indicator. The calcium carbonate didn't really change at all but it is a little bit crusty, but the baby flower petal was pink before and it started losing it colour. Lastly, the apple is harder than before as time goes by. Each equipment changed because of the acid rain.
Explanation:
The equipment change and react to the effects of the acid rain because of the acid that's been attached to them.
