1) Calculate the total hardness for the first sample (Sample Volume,V : 50 mL,Volume of EDTA titrant used for the sample, A:9.6 mL)
2)Calculate the calcium and magnesium concentrations for the first sample in the video in meq/L and mg CaCO3/L.(Sample Volume= 50 mL, Magnesium hardness titrant volume = 0 mL, Calcium hardness titrant volume:2,6 mL)
3)Assuming the pH and alkalinity of the first sample in the video are 7.5 and 100 mg CaCO3/L, respectively, calculate the temporary and permanent hardness values for this sample
4How much CaCL2 in meq/L should be added to the sample to equalize calcium and magnesium hardness? Which hardness level (soft, medium, hard, very hard) does the sample belong to after this addition?
