Optimum Vol NaOH = 30mL

O.1M NaOH

Calculate grapms KHP you must weight out to react with NaOH present in that volume.

The answer is 0.6121 g KHP. Can someone explain how to find this?

Answer #1

Balanced chemical reaction between KHP and NaOH

NaOH + KHC8H4O4 KNaC8H4O4 + H2O

no. of mole = molarity X volume of solution in liter

no. of mole of NaOH = 0.1 X 0.030 = 0.0030 mole

According to balanced chemical reaction 1 mole of NaOH react with 1 mole of KHP then to react with 0.0030 mole of NaOH required KHP = 0.0030 mole

molar mass of KHP = 204.22 g/mol then 0.0030 mole of KHP = 0.0030 X 204.22 = 0.6126 gm

0.6126 gm of KHP requird to react with 30 ml 0.1M NaOH

n this exercise, weighed samples of a solid unknown containing NaCl and NaHCO3 react with hydrochloric acid. The volume of the CO2 liberated by the reaction in the gas phase is measured with a gas collection syringe. From the volume we can calculate the number of moles of CO2 in the gas phase using the ideal gas approximation. Since the CO2 is generated in an aqueous environment (aqueous HCl), some CO2 will dissolve in the liquid phase. The amount of...
