Solution Preparation Calculations There are three solutions that need to be made. Be sure to have the calculations for all three of these solutions. Since these volumes are enough for the entire lab, I will assign lab groups to make different solutions (but calculations for all solutions need to be in your lab notebook). On the "Observations" side of the protocol, state who is preparing the solution. Solution 1 (Buffer) 0.1 M Sodium phosphate buffer, pH 6.8. Prepare 500 ml....
