The following experimental process steps have been made to determine the hardness of water. Accordingly, 100 mL sample was acidified with a few drops of 6 M HCl and boiled for a while to remove the CO2 in it. Then add a few drops of methyl red 6pH: 4.2-6.3) to the cooled sample and neutralize the solution with 0.1M NaOH, then add 2 ml of 0.01M pH10 buffer and 4-5 drops on it. EBT indicator was added and the solution was titrated with 0.0086M EDTA until the color turned blue. Since the consumption of titrant is 11.44mL, calculate the amount of Ca in the water in terms of mg CaCO3. (Ca: 40, C: 12, 0:16) A. 8,75 O B. 9,83 C. 10,44 D. 10,35 Reset Selection

Question

The following experimental process steps have been made to determine the hardness of water. Accordingly, 100 mL sample was acidified with a few drops of 6 M HCl and boiled for a while to remove the CO2 in it. Then add a few drops of methyl red (pH: 4.2-6.3) to the cooled sample and neutralize the solution with 0.1M NaOH, then add 2 ml of 0.01M pH10 buffer and 4-5 drops on it.

EBT indicator was added and the solution was titrated with 0.0086M EDTA until the color turned blue. Since the consumption of titrant is 11.44mL, calculate the amount of Ca in the water in terms of mg CaCO3. (Ca: 40, C: 12, 0:16)
