What is an insoluble salt?

An insoluble salt is a salt which dissolves very very little in water. Be careful! Very many say that insoluble means that it cannot dissole in water. It's not true. There is NO substance that cannot dissolve in water. They dissolve VERY little so it's considered that they don't dissolve.
Soluble salts are considered the ones having an alkali or an alkali earth metal in their structure. All the others are insoluble.
