A student performs a serial dilution but is not careful about the correct procedures for using the pipet and volumetric flask. Explain how the following errors would affect the concentrations of the diluted solution: a) The pipet is rinsed with water, but not with the solution that is measured. b) The student uses the rubber bulb to force out the liquid remaining in the tip of the pipet into the volumetric flask. c) After carefully mixing the diluted solution in the volumetric flask, the student pours the solution into a beaker that was not carefully rinsed with solution.
