For no. 1: Bases and Acids are opposite from each other.  An acid is any chemical substance that when it dissolves in water, it creates a solution with a hydrogen ion activity greater than water. Any substance with a pH less than 7.0 is an acid, and includes, for example,  sauerkraut or pickles.

A base is any chemical substance dissolves in water, creates a solution where hydrogen ion activity less than water.  Any substance with a pH greater than 7.0 is a base, and includes, for example, bleach or ammonia.
