Dilutions

Front

What happens to the volume and molarity when a solution is diluted?

Back

The volume increases and the molarity (M) decreases.

Front

What is a dilution?

Back

A dilution is when water is added to the volume of a solution.

Front

How do you calculate the concentration after diluting a solution?

Back

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

Front

What is the molarity (M) of a solution?

Back

Molarity (M) is a measure of the concentration of a solute in a solution, defined as moles of solute per liter of solution.

Front

If you dilute 250 mL of 0.10 M lithium acetate to 750 mL, what is the new concentration?

Back

0.033 M.

Front

What is the formula to find the amount of solute in a solution?

Back

Amount of solute (in moles) = Molarity (M) × Volume (L).

Front

What is the relationship between volume and concentration in a dilution?

Back

As the volume increases, the concentration decreases.

Front

If 125.0 mL of 2.00 M calcium hydroxide is diluted to 1.50 M, how much water is added?

Back

42.0 mL.

Front

What does the term 'molar' refer to in chemistry?

Back

The term 'molar' refers to the concentration of a solution, expressed in moles of solute per liter of solution.

Front

What is the effect of adding more solute to a solution?

Back

Adding more solute increases the concentration of the solution.
