Complete the 4 practice Concentration Calculations Complete the 4 practice Concentration Calculations. Every student needs to do their own, put their name on it, and place it in the warm-up folder  Warm-Up 2/6/14

Dilution Thursday, 2/6/14

Solution Composition Dilute: “weak”, little dissolved solute present Concentrated: “strong”, large amount of solute

Dilution Dilution: reducing the concentration of a chemical or solution. Usually done by increasing the ratio of solvent in the solution

C1V1=C2V2 C1= starting concentration (M) V1= starting volume C2= new concentration (M) V2= new volume

Example) A chemist starts with 0. 25L of a 0 Example) A chemist starts with 0.25L of a 0.40 M NaCl solution and dilutes it to 1.0L. What is the concentration of NaCl in the new solution? C1= V1= C2= V2=

Example) What volume 0. 20 M glucose solution can be made from 0 Example) What volume 0.20 M glucose solution can be made from 0.025L of 0.50 M glucose solution? C1= V1= C2= V2=

Your Job Complete the Purpose and Pre-lab Calculations. You need to get them stamped by me before the end of the hour today. IMF Reports DUE tomorrow!
