Potassium hydrogen phthalate (KHP) is a monoprotic acid and is often used as a primary standard in acid-base titrations. If 19.3 mL of 0.1252 M NaOH is required to neutralize 0.6716 g of impure KHP sample, what's the % of KHP in the sample?
Potassium hydrogen phthalate (KHP) is a monoprotic acid that is used to standardize NaOH. If 21.39 mL of NaOH is required to titrate 0.6422 g of KHP, what is the concentration of NaOH? The molar mass of KHP is 204.2 g/mole. a. 1.374 × 10-2M b. 2.805 × 10-2M c. 8.931 × 10-2M d. 1.470 × 10-1M e. 3.002 × 10-1M
1. a. Potassium hydrogen phthalate, KHP, (KHC8H4O4), is a monoprotic primary standard used to standardize solutions of NaOH. What concentration (M) of NaOH is used if 35.12 mL of the NaOH solution is required to neutralize 2.734 g KHP? b. In a lab procedure, the instructions are to dissolve the Potassium hydrogen phthalate, KHP, in 100 mL of water. Will the amount of water used to dissolve the KHP affect the lab results? Explain.
