A volume of 20.05 mL of NaOH was used to titrate a 0.45 g sample of potassium hydrogen phthalate (KHP), a monoprotic acid, which has a molecular weight of 204.2 g/mol. Calculate the molarity of the NaOH solution. For the above titration of potassium hydrogen phthalate with NaOH, if you have the following pH indicators: methyl red, bromothymol blue, and phenolphthalein, which indicator should you use? Explain why.
A 1.413-g sample of KHP takes 19.43 mL of a NaOH solution to titrate it to a phenolphthalein end point. What is the molarity of the NaOH solution? The molar mass of KHP is 204.2g/mol.
Potassium hydrogen phthalate (KHP) is used to standardize sodium hydroxide. If 15.18 mL of NaOH(aq) is required to titrate 0.5614 g KHP to the equivalence point, what is the concentration of the NaOH(aq)? (The molar mass of KHP = 204.2 g/mol) HCH,0, (aq) + OH (aq) SCH,02 (aq) + H,0(1)
formula for KHP is KC8H5O4
