Acid rain had the lowest pH so it was more acidic.
The metal nail in the acid rain water disintegrated.
Acid rain had the least effect on the brick.
The nail in the rainwater rusted.
Rainwater had least effect on the concrete, roof shingle, and the brick.
The nail in the tap water rusted as well.
Tap water had least effect on the brick.
If I were to build the top of a house I would use brick. I
would use brick instead of roof
shingle at the top of the house because the acid rain, rainwater, and tap water had least
affect on the brick.
I would not build my house out of wood because your house could
burn if you live in an acid rain
area. I saw this in my experiment. The chopstick was made out of wood and the acid
traveled up the string and discolored the wood.
