Molarity (M) of the NaOH solution NG 0.5 NG 0.5Explanation / Answer
1 mole of KHP reacts with 1 mole of NaOH
Trial #1,
moles of KHP reacted = 0.023319 M x 19.6 ml = 0.46 mmol
moles NaOH added = 0.46 mmol
volume of NaOH to reach equivalence point = 3.0 ml
molarity of NaOH solution = 0.46 mmol/3 ml = 0.153 M
Trial #2,
moles of KHP reacted = 0.023319 M x 19.75 ml = 0.46 mmol
moles NaOH to reach equivalence point = 0.46 mmol
volume of NaOH to reach equivalence point = 3.0 ml
molarity of NaOH solution = 0.46 mmol/3 ml = 0.153 M
Average molarity of NaOH = 0.153 M
