SOlubility & net Ionic equations

Front

What is solubility?

Back

Solubility is the ability of a substance (solute) to dissolve in a solvent, forming a solution. It is often expressed in terms of concentration (e.g., grams per liter).

Front

What is a precipitate?

Back

A precipitate is an insoluble solid that forms when two solutions are mixed and a chemical reaction occurs.

Front

What is a net ionic equation?

Back

A net ionic equation shows only the species that participate in a chemical reaction, omitting the spectator ions.

Front

What are spectator ions?

Back

Spectator ions are ions that do not participate in the actual chemical reaction and remain unchanged in solution.

Front

What is the solubility rule for nitrates?

Back

All nitrates (NO3-) are soluble in water.

Front

What is the solubility rule for chlorides?

Back

Most chlorides are soluble in water, except for those of silver (Ag+), lead (Pb2+), and mercury (Hg2+).

Front

What is the solubility rule for sulfates?

Back

Most sulfates are soluble in water, except for those of barium (Ba2+), lead (Pb2+), and calcium (Ca2+).

Front

What is the solubility rule for hydroxides?

Back

Most hydroxides are insoluble in water, except for those of alkali metals and barium (Ba2+).

Front

What is the product of mixing lead (II) nitrate and sodium chloride?

Back

The product is lead (II) chloride, which is an insoluble precipitate.

Front

What is the product of mixing copper(II) chloride and sodium hydroxide?

Back

The product is copper(II) hydroxide, which is an insoluble precipitate.
