Aqueous Solutions

Front

What is an aqueous solution?

Back

An aqueous solution is a solution in which water is the solvent.

Front

What is the formula for calculating molarity?

Back

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

Front

What is the universal solvent?

Back

Water is known as the universal solvent because it can dissolve many substances.

Front

What is the dilution formula?

Back

The dilution formula is M1V1 = M2V2, where M is molarity and V is volume.

Front

How do you calculate the number of moles from molarity and volume?

Back

Moles = Molarity (M) x Volume (L).

What is the mass of HCl needed to make a 3M solution in 4L?

Back

437.52g.

Front

What is a solution?

Back

A solution is a homogeneous mixture composed of two or more substances.

Front

What is the difference between a solute and a solvent?

Back

A solute is the substance that is dissolved, while a solvent is the substance that does the dissolving.

Front

What is the concentration of a solution?

Back

Concentration is the amount of solute present in a given volume of solution.

Front

How do you prepare a diluted solution from a concentrated solution?

Back

Use the dilution formula: M1V1 = M2V2.
