Reactions in Aqueous Solutions Review

A weak electrolyte is a substance that partially ionizes in water, resulting in a solution that conducts electricity poorly.

Ag+(aq) + Cl-(aq) → AgCl(s)

A precipitate is an insoluble solid that forms when two aqueous solutions react.

Concentration (M) = moles of solute / volume of solution (L).

The molar mass of Na2SO4 is 142.04 g/mol.

It forms a precipitate of AgOH.

Molarity (M) = moles of solute / liters of solution.

Water acts as a solvent, allowing solutes to dissolve and ionize.

Strong electrolytes completely ionize in solution, while weak electrolytes only partially ionize.
