Solubility and Precipitation reactions

Front

What is solubility?

Back

Solubility is the ability of a substance (solute) to dissolve in a solvent, forming a homogeneous solution.

Front

What is a precipitation reaction?

Back

A precipitation reaction occurs when two soluble salts react in solution to form an insoluble salt, known as a precipitate.

Front

What factors affect solubility?

Back

Factors affecting solubility include temperature, pressure, and the nature of the solute and solvent.

Front

What is the solubility rule for most sulfides?

Back

Most sulfides are insoluble in water, except for those of alkali metals and alkaline earth metals.

Front

What is the solubility rule for hydroxides?

Back

Most hydroxides are insoluble, except for those of alkali metals and some alkaline earth metals like calcium, strontium, and barium.

Front

What is the solubility rule for nitrates?

Back

All nitrates are soluble in water.

Front

What is the solubility rule for acetates?

Back

Most acetates are soluble in water, with silver acetate being a notable exception.

Front

What is the solubility rule for chlorides?

Back

Most chlorides are soluble, except for those of silver, lead, and mercury.

Front

What is the solubility rule for carbonates?

Back

Most carbonates are insoluble, except for those of alkali metals and ammonium.

Front

What is the role of temperature in solubility?

Back

Generally, solubility of solids increases with temperature, while the solubility of gases decreases.
