50.00 mL aliquot of city drinking water was treated with a small amount of ammonia – ammonium chloride buffer to bring the pH to 10. After the addition of EBT indicator the solution required 10.00 mL of 8.000 x 10-3 M EDTA for titration. Calculate the hardness in terms of parts per million calcium carbonate (100.0869 g/mol). 320 160 ppm 4 80
