what forms a white precipitate?

(Old Chem.) A heavy white amorphous powder (NH2. HgCl) obtained by adding ammonia to a solution of mercuric chloride or corrosive sublimate; - formerly called also infusible white precipitate, and now amido-mercuric chloride.

Beside above,What solution forms a white precipitate?

Precipitate tests

Metal ion Result on adding NaOH or NH 3 solution Effect of adding excess NaOH solution
aluminium, Al 3+ white precipitate white precipitate dissolves and a colourless solution forms
zinc, Zn 2+ white precipitate white precipitate dissolves and a colourless solution forms

Additionally,What causes a white precipitate to form?

Precipitation occurs more rapidly from a strongly supersaturated solution. The formation of a precipitate can be caused by a chemical reaction. When a barium chloride solution reacts with sulphuric acid, a white precipitate of barium sulfate is formed.

Accordingly,Which precipitates are white?

Therefore, barium carbonate, barium sulfate and barium sulfite are white precipitates.

Correspondingly,Why does chloride form a white precipitate?

When a few drops of a silver nitrate solution are added to a slightly acidic aqueous solution that contains chloride ions, a white precipitate of silver chloride will form.

Which ion forms a white precipitate with aqueous sodium hydroxide?

A few drops of dilute sodium hydroxide solution react to form a white precipitate with aluminium ions, calcium ions and magnesium ions. However, if excess sodium hydroxide solution is added: the aluminium hydroxide precipitate dissolves to form a colourless solution. the calcium hydroxide precipitate is unchanged.

What forms white precipitate with sulfuric acid?

Calcium, strontium and barium When exposed to sulfuric acid, a layer of insoluble sulfate is formed on each of these metals, slowing or stopping the reaction entirely. In the calcium case, some hydrogen is produced, along with a white precipitate of calcium sulfate.

What forms a white precipitate with barium chloride?

barium sulphateWhen barium chloride reacts with zinc sulphate, it results in the formation of a white precipitate known as barium sulphate.

What produces a precipitate?

Formation of an insoluble compound will sometimes occur when a solution containing a particular cation (a positively charged ion) is mixed with another solution containing a particular anion (a negatively charged ion). The solid that separates is called a precipitate.

What forms a white precipitate with sodium carbonate?

If a white precipitate forms, the salt is either a sulfate or a carbonate. If the precipitate is treated with nitric acid, it is possible to distinguish whether the salt is a sulphate or a carbonate (as in the test for a chloride).

Is nano3 a white precipitate?

Answer: Both silver nitrate and sodium chloride solutions are colourless solutions. When they react with each other, white precipitate and colourless solution is given. Sodium nitrate is colourless water soluble compound.
