Drink too sweet! What do you do?

1 g of solute in 1 L of water C= 1g/L 3 L of water 1 g of solute in 4 L of water C= 0.25g/L

Reducing the concentration of a solution by the addition of solvent What is Dilution? Reducing the concentration of a solution by the addition of solvent

What’s happening to: Solute? Solvent? Concentration? 1 g of solute in 1 L of water C= 1g/L 3 L of water What’s happening to: Solute? Solvent? Concentration? 1 g of solute in 4 L of water C= 0.25g/L

Dilution When you are diluting a substance the amount of solute remains the same The volume of solvent increases Therefore the concentration decreases

Formula C1V1 = C2V2

Practice Problem Morgan had 50ml of 20g/L solution of Kool-Aid. She found it to be too sweet so she added another 50ml of water. What is the final concentration (g/L)? Given: Find:
