An acid is a substance that has a pH of 0-6
A neutral substance has a pH level of 7 (water)
A base has a pH level of 8-16


pH = power of Hydrogen

Acids such as HCl (the acid in your stomach that helps you digest your food) or lemon juice are all acids because their pH is lower than 7 (neutral).
When you are neutral, you have a pH level of 7, for example water.
When you have a basic substance, you are a base with a pH level of 8-16. Things like soap or bleach are all considered bases.
