Q/ Mohr's method uses the potassium chromate indicator and this indicator makes the equivalent point not identical to the end point. A sample weighing 5.592 g of BaCl2 is dissolved in 500 mL of water. Calculate the percentage of chloride in the sample when 25 mL of the sample is titrated and requires 33.47 mL of 0.1098 N AGNO.
