hardness of water lab report ..
I don't know ehat is the difference between volume of EDTA and volume of EDTA used to titrate blnk ,, so I could not find the molarity of EDTA
I could not complete the lab report .. how can I calculate these results ?
I don't have anything known other than tie Burette readings
