Please show all steps. Thanks!
A solution of NaOH was standardized by titration of a known quantity of the primary standard potassium hydrogen phthalate (KHP) which has a formula of KC8H5O4.
The NaOH was then used to find the concentration of an unknown solution of H2SO4.
Titration of 0.824g of KHP required 38.314g of NaOH solution to reach the endpoint detected by phenolphthalein indicator. Determine the concentration of NaOH expressed as mol NaOH/g solution. A 10mL sample of H2SO4 was found to require 57.911g of the NaOH solution to reach the phenolphthalein end point. Find the molarity of the H2SO4.
