Question

Determine how the following scenarios will affect the calculations in Parts A. B and C. a. How will the concentration of NaOH be affected if during the titration some of the solid potassium hydrogen phthalate was spilled during the transfer? Will the concentration of the standardized NaOH increase, decrease or have no effect? Explain. b How will the molar mass be affected if some of the solid remained after the titration was complete? Will the molar mass increase decrease or have no effect? Explain. c. How will the concentration of acetic acid in vinegar be affected if the liquid retained in the pipet is blown out? Will the concentration of acetic acid in vinegar increase, decrease, or have no effect? Explain.

Explanation / Answer

Solution

A) The concentration of the NaOH will increase as there is removal of the solid so the volume will decrease which will help in increasing in concentration of NaOH

B) The molar mass of the solid will decrease as the moles will be more of solvent

C) The concentration of the acetic acid will increase as the volume is again decreasing as the liquid is removed from the system and which will eventually increase the conc of acetic acid
