Reference no: EM13181252

1) Use the molarity of the EDTA solution and the average volume of EDTA added to calculate the average number of moles of EDTA required for the titration.

Molarity EDTA= .01 & Volume EDTA= .01755 L

Find moles?

2) EDTA reacts with the hard water ions in a 1:1 ratio. Calculate the total number of moles of the metal ions present in the 50 mL of water tested?

3) An experiment to find water hardness required 18.2 mL of 0.0050 M EDTA solution to titrate 40.0 mL of tap water using an Eriochrome Black T indicator. Find the parts per million of calcium.
