What is a weak electrolyte?

Back

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

What is the net ionic equation for the reaction of AgNO3 and CaCl2?

Back

Ag+(aq) + Cl-(aq) → AgCl(s)

Front

What is a precipitate?

Back

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

Front

What is the oxidation number of Mn in MnO2?

Back

+4

How do you calculate the concentration of sodium ions in a solution?

Back

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

Front

What is the molar mass of sodium sulfate (Na2SO4)?

Back

The molar mass of Na2SO4 is 142.04 g/mol.

Front

What happens when AgNO3 reacts with NaOH?

Back

It forms a precipitate of AgOH.

Front

What is the formula for calculating molarity?

Back

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

Front

What is the role of water in aqueous solutions?

Back

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

Front

What is the difference between strong and weak electrolytes?

Back

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