Water and Solutions REVIEW

Front

What is an unsaturated solution?

Back

A solution where more solute can still be dissolved at the given temperature.

Front

What two elements make up water?

Back

Hydrogen and oxygen.

Front

Why is water considered a universal solvent?

Back

Because it dissolves most substances.

Front

What is the name of the solute if 50g is dissolved in 100g of water at 50℃?

Back

NH4Cl.

Front

How do you calculate the final volume of a diluted solution?

Back

Use the formula C1V1 = C2V2, where C is concentration and V is volume.

Front

What is a saturated solution?

Back

A solution that contains the maximum amount of solute that can be dissolved at a given temperature.

Front

What is a supersaturated solution?

Back

A solution that contains more solute than can normally be dissolved at a given temperature.

Front

What happens to water when it freezes?

Back

It expands and floats due to lower density.

Front

What is molarity?

Back

Molarity is a measure of concentration, defined as moles of solute per liter of solution.

Front

What is the formula for calculating moles of solute?

Back

Moles = Molarity x Volume (in liters).
