Question

You perform your first titration using your NaOH with a KHP solution. Your KHP solution is made with 0.4410 g of KHP. The initial amount of NaOH in your pipette is 17.55 mL and the final amount in your buret is 37.16 mL when the indicator changes color. Determine the concentration of your NaOH solution. Write your answer to four decimal places without units. For your second titration, you put 0.484 g of KHP in your flask. Pretend that the concentration of NaOH you calculated in the previous problem was 0.1040. Predict the volume (in mL) of NaOH you will use in this titration. Write your answer to two decimal places without units. In this problem, you will determine the % relative standard deviation (%RSD) from a series of titrations. Pretend that the [NaOH] you measured in your three titrations are 0.0992, 0.1041, and 0.0966. Determine the %RSD of these three values. Write your answer to one decimal place.
