Acid Rain Experiment
What is acid rain? Acid rain is when the air gets so polluted with fossil fuels it gets absorbed by the clouds and comes out in an acidic form when it rains, it is environmentally harmful.
Aim: To observe effects of acid rain
Hypothesis: Petal- dry out calcium carbonate- become liquid apple-dry out, universal indicator- get dark bromothymol blue- lighten.
Method: In a petri dish place items around weigh boat which is in the middle of the dish, wet-dry ingredients with a drop of water. Add a spatula of sulfate to weigh boat, add 5 drops of sulfuric acid. quickly close.
observation: bromothymol blue is turning yellow/orange, the universal indicator is turning pink, the petal is getting slightly lighter. I think it's because acid eats way at things so it diluted the colour.
