An insoluble solid formed when substances react in a solution.

An insoluble solid formed during a reaction in a solution.

This solid is a precipitate. The suspended particles scatter light, making the limewater appear milky or cloudy rather than remaining clear.

An insoluble solid that forms when two solutions react.

An insoluble solid formed during a reaction involving solutions.

An insoluble solid that forms when solutions react.

An insoluble solid formed when ions in solutions react together.

A precipitate such as barium sulfate remains written as one solid formula.

An insoluble solid formed when substances in solution react.

An insoluble solid formed within a solution during a chemical reaction.

A solid that forms when dissolved substances react in a solution.

An insoluble solid formed in a solution during a precipitation reaction.

A solid that forms from a reaction in a solution; suspended particles can make the mixture cloudy.

An insoluble solid that forms when substances in solution react.

An insoluble solid that forms when ions in solutions react together.

An insoluble solid formed when suitable aqueous ions react together.

An insoluble solid that forms when two solutions react.

An insoluble solid formed when substances in solution react.

For example, mixing silver nitrate solution and sodium chloride solution produces solid silver chloride, a precipitate.

A solid formed within a solution during a chemical reaction.

An insoluble solid formed when ions in solutions react together.

A solid formed when substances in solution react.

An insoluble solid that forms when solutions react.

An insoluble solid formed during a reaction in a solution.

An insoluble solid formed when substances in solution react.

An insoluble solid formed when substances in solutions react.

An insoluble solid formed when two solutions react.

An insoluble solid formed when substances react in solution.

A solid formed when substances react in solution; it may make the mixture cloudy.

If asked for the cause of the milky appearance, name the insoluble calcium carbonate precipitate.

When identifying an ion, give both the precipitate colour and what happens in excess sodium hydroxide where relevant.

Do not identify a white precipitate as aluminium until it has dissolved in excess sodium hydroxide. Calcium and magnesium hydroxides remain, so this test alone cannot distinguish between their ions.
