ionic compound precipitate from a solution of the constituent ions is when the solution is basic or acid. first the ionic compound is allowed to dissociate into ions, when almost all the ions are dissociated a strong acid or base is added to change the ph, in order to precipitate the ions
By Anne Marie Helmenstine, Ph.D. Precipitate Definition: to form an insoluble compound either by reacting two salts or by changing the temperature to affect the solubility of the compound. Also the name given to the solid that is formed as a result of a precipitation reaction.Example: Mixing silver nitrate and sodium chloride in water will cause silver chloride to precipitate out of solution as a solid.Return to the Chemistry Glossary Index.lso the name given to the solid that is formed as a result of a precipitation reaction.
