Titration of 0.8443 g of KHP required 42.145 g of NaOH solution to reach the endpoint detected by phenolphtalein indicator.
A. Find the molality of the NaOH solution (units: mol NaOH/ kg water)
B. A 12.00 ml aliquot of H2SO4 required 62.334 g of this NaOH solution to reach the phenolphtalien end point. Determine the molarity of the sulfuric acid solution?
