1)During the course of this experiment you will need to use the same glassware to transfer liquids of different concentrations. To avoid contaimination, the pipettes used will be rinsed with the solution to be transferred to wash out remnants of the solution that was previously transferred. Suppose you were going to use a pipette to transfer 25.00 mL of a 1.00 M glucose solution. You didn't rinse out the pipette first and 1.00 mL of the previous, 2.00 M solution remained inside. You end up drawing up 24 mL of 1.00 M solution in addition to the prior 1.00 mL. What is the concentration of glucose in the 25 mL in the pipette? What percent error in concentration is there compared to the 25 mL of 1.00 M solution that you should have? calculation: [ ]1 x V1 = [ ]2 x V2

2) A 1 M solution of acetic acid is generated and a pH of 4.74 is measured. What is the percent dissociation (ionization of the molecular acid? [H30^+]= 10 ^-pH
