Suppose that in your standardization procedure of sodium hydroxide with KHP, you went one milliliter past the actual phenolphthalein endpoint while you performed the titration. Explain how would this affect your calculated value of the concentration of the sodium hydroxide solution? Would the computed concentration be too large or too small compared to the correct concentration?
