Acids and bases are substances which change the balance of hydrogen and hydroxide ions in water. Both are divided into two categories - strong acids or bases which ionize completely in water, and weak acids or bases which ionize only partially in water.
Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory.
