creating hard water from distilled water in lab
« on: December 24, 2014, 02:17:30 AM »
Is it possible to create hard water in the lab from distilled water by adding water soluble calcium salts to carbonate/ bicarbonate buffer of ph7.5?

Definitely.

I would measure the conductivity first - if you're getting a measure of circa 100µS to begin with then you're doing well. Add the calcium carbonate until you get the conductivity value for the comparable sample.
