- Questions and Comments
- Useful References
- Topics Covered
- Molarity
- Normality
- pH
- Acid-Base Chemistry
- Chemical Equilibrium
- Acid Rain
- Carbonate Buffering
- Alkalinity
- (Va)(Ma)=(Vb)(Mb); a=acid, b=base V=volume M=molarity
- pH=-log [H+]
- 1 X 10-14 = [H+][OH-]
- (Va)(Na)/Vs = concentration of the alkalinity species. a=acid, N=normality of the acid,Vs=volume of your starting solution (unknown)
- Vp= the volume of acid needed to neutralize the OH and CO3 in the unknown
- Vmo = the volume of acid needed to neutralize the HCO3 in the unknown.
- CaCo3 (mg) = (Va)(Na)(1000 meq/eg)(# equivalents)(1/volumeof solution)(50 mg CaCo3; remember the # of equivalents is determined by whatever species you are solving for.) For example, [OH-]=1 equivalent CO3 (2-) = 2 equivalents.
