Chemical bond
A compound made of oppositely charged ions
Ionic compound
A chemical compound formed by the sharing of electrons
Covalent compound
Any compound that increases the number of hydronium ions when dissolved in water
Acid
A compound that can reversibly change color depending on conditions such as pH
Indicator
Any compound that increases the number of hydroxide ions when dissolved in water
Base
The reaction of an acid and a base to form a neutral solution of water and a salt
Neutralization reaction
A value that is used to express the acidity or basicity (alkalinty) of a system

An ionic compound that forms when a metal atom replaces the hydrogen of an acid
Salt
A covalently bonded compound that contains carbon
Organic compound
