Answer:
Suppose you are standardizing a sodium hydroxide solution with KHP
(molar mass=204.2 g/mol) according to the equation
KHP+NaOH⟶H2O+NaKP
You prepare the standard solution from 0.303 g of KHP
in 250.0 mL of water. You then require 9.51 mL of NaOH
solution to complete the titration.
What is the concentration of the NaOH
solution?
Answer:
The concentration of the NaOH solution can be calculated using the following equation:
Concentration (M) = (Moles of KHP/Volume of NaOH solution) x (Molar mass of KHP/1000)
Concentration (M) = (0.303 g/9.51 mL) x (204.2 g/mol/1000)
Concentration (M) = 0.064 M
