Science - Acid Rain

Acid Rain:
Acid rain makes chemical weathering happen more quickly. When fossil fuels likes coal, oil and natural gases are burned, oxides of carbon and sulfur escape into the air. These molecules dissolve in the water that's from the clouds and makes rainwater more acidic then normal. The process is called acid rain.

The process
1. Burning of fossil fuels.
2. Molecules dissolve.
3. Precipitation.

Method:
Put a moist apple, petal and calcium carbonate petri dish spaced apart. After put three drops of universal indicator, bromothynal indicator spaced apart. Get a weigh boat and put sodium solfid plus water and sulphuric acid and mix together.  Afterwards put the lid on the top of petri dish.

Observations:
Universal indicator was green and turned red.
Bromothynal indicator was blue and turned green/yellow.
Petal lost a bit of it's colour and was hard.
Apple turned hard.
Calcium carbonate turned crusty.
