Concentration of EDTA solution= 0.01M
Volume of water sample used= 50ml
Now, we can calculate the concentration of hardness ions in the water sample using the formula:
Concentration of hardness ions (mg/L) = (Volume of EDTA used x Concentration of EDTA x Molar mass of CaCO3) / Volume of water sample used
Concentration of hardness ions = (8.47ml x 0.01M x 100.09g/mol) / 50ml
Concentration of hardness ions = 0.01694g / 50ml
Concentration of hardness ions = 0.3388 mg/L
Therefore, the concentration of hardness ions in the water sample is 0.3388 mg/L.
Volume of water sample used= 50ml
Now, we can calculate the concentration of hardness ions in the water sample using the formula:
Concentration of hardness ions (mg/L) = (Volume of EDTA used x Concentration of EDTA x Molar mass of CaCO3) / Volume of water sample used
Concentration of hardness ions = (8.47ml x 0.01M x 100.09g/mol) / 50ml
Concentration of hardness ions = 0.01694g / 50ml
Concentration of hardness ions = 0.3388 mg/L
Therefore, the concentration of hardness ions in the water sample is 0.3388 mg/L.

To determine the hardness of water through complexometric titration, you need to use the following formula:
Hardness (mg/L CaCO3) = (Volume of EDTA used (mL) - Concentration of EDTA (mg/L)) / (Volume of water sample used (mL))
In this case, the average volume of EDTA used is 8.47 mL. However, you have not provided the concentration of EDTA used or the volume of water sample used. Therefore, I cannot calculate the hardness of the water from the given data.
Please provide the missing data so that I can accurately determine the hardness of the water.
