TITLE: ACIDS AND BASES
An acid is corrosive, eg lemon. A base cleans something. eg soap.
Acid ph level is below 7 base ph level is above 7.
I put acid in with metal, and it melted the metal into hydrogen gas then
Bubbles formed, and if you put a piece of wood split open with fire then it would make a pop sound to test if it had any gases.
It’s hard to understand some things in science e.g. periodic table and atoms, balancing chemical equation.
