What is the equivalent weight for concentration of 100mg/l of MnSO4 when expressed as CaCO3?
What is the equivalent weight for concentration of 100mg/l of MnSO4 when expressed as CaCO3?
Determine the hardness of this water in units of mg/L as CaCO3. Hardness is the sum of the concentrations of multivalent cations in the water, which in this case include Ca (as Ca2+) and Mg (as Mg2+). Hardness is expressed in “equivalent” units or “CaCO3” units.
Calculate solubility of NaCl and CaCO3
3) Calculate the solubility of (a) NaCl (expressed in g/L) and (b) CaCOs (expressed in mg/L), given values of 1.54 and -8.35, respectively, for their solubility products (given as log Ksp values). Hint: review Table 6-2 in the Lab 1 handout.
