Hello again my precious prends!!
So today my class is gonna experiment with something but I do not know yet, but I think we're experimenting with something about acids. So here we go guys, but i write about the acid rain first.
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 is to observe the effects of acid. "Aaah ok ok".
Hypothesis.
Petal, Calcium Carbonate, Apple, Universal indicator, Bromothymol Blue.
Method.
In a Petri dish place items around the edge. Wet dry ingredients with a drop of water. In the middle, put a weight bout.
Observation
The Universal indicator changed its color to red, Bromothymol blue to yellow, and Petal to lighter clour of its color. and the only color that didn't change were calcium carbonate and apple.
