For the sake of calibrating my water softener I am trying to test the Total Hardness of the water coming to my home. I have read that the standard Calcium Hardness test uses of R-0010 (Sodium Hydroxide) as a base/buffer is to avoid interference with Magnesium. As I understand it at high pH the Magnesium will precipitate out. In order to measure Total (Calcium + Magnesium) Hardness can I simply not use R-0010 leaving the pH at about 7.5 and the Magnesium in solution?
Thanks,
Mike
