105 Chemistry I Laboratory Manual, 2017 Revision Questions: 1) What mass of KHP would you need in order to use 35.00 mL of 0.400 M NaOH to titrate it? 2) A student weighs out 1,000 g of impure KHP, dissolves the sample in deionized water and titrates it with 0.1101 M NaOH solution. If the titration requires 22.10 mL of the NaOH solution, and none of the impurities react with NaOH, what is the percent KHP in the sample?

As part of Lab 11 you will make and standardize a solution of NaOH(aq). Suppose in the lab you measure the solid NaOH and dissolve it into 100.0 mL of water. You then measure 0.1993 g of KHP (204.22 g/mol) and place it in a clean, dry 100-mL beaker, and then dissolve the KHP in about 25 mL of water and add a couple of drops of phenolphthalein indicator. You titrate this with your NaOH(aq) solution and find that the...

i need help with these three questions
Incorrect Question 2 0/1.25 pts 0.678 g of KHP is used to standardize a NaOH solution. If it took 31.55 mL of NaOH to neutralize the KHP, what is the concentration of the NaOH solution? The molar mass of KHP is 204.22 g/mol. KHP + NaOH --> NaKP + H2O Give the answer to 3 sig figs and use units of M 0.0214 Unanswered Question 3 0/1.25 pts A 25.00 mL HCl sample...

Experiment 7, Analysis of KHP by titration with NaOH Wright College, Department of Physical Science and Engineering In this experiment, you will determine the amount (percent) of potassium hydrogen phthalate (KHP) that is in an impure sample. You will determine the percent of KHP via titration using NOH with known inolarity. The reaction will follow, KHCgH00, (aq) + NaOH (aq) ---------> KNaCHO, (aq) + H20 (I) At the end point, the...
