So I have Ca in mg/L which was found from CaCO3 + EDTA4- → CaEDTA2- + CO32- or not?

Alkalinity - http://www.ehow.com/how_5328969_calculate-alkalinity-caco.html Hardness - Water hardness is a measure of the amount of calcium and magnesium salts dissolved in water. There are no health hazards associated with water hardness, however, hard water causes scale, as well as the...

Oh yeah mili- means *10-3 not *10-1 m=2.3*10-5g M(H)=1g/mol n=m/M=2.3*10-5mol c=n/V=2.3*10-5mol/l pH = -log [H+]=-log[2.3*10-5]=4.638 Is that it in terms of pH?

m=0.0023g M(H)=1g/mol n=m/M=0.0023mol c=n/V=0.0023mol/l ?

pH = -log [H+]=-log[0.23*10-2]=2.638 ??

The mathematical definition of pH is a bit less intuitive but in general more useful. It says that the pH is equal to to the negative logarithmic value of the Hydrogen ion (H+) concentration, or pH = -log [H+] pH can alternatively be defined mathematically as the negative logarithmic value...
