The problem of components
« on: May 24, 2005, 12:21:38 PM »
Can anyone please tell me how many components there are in an unsaturated solution of NaH2PO4 in water? and how different is this example from, say, an unsaturated solution of Na2HPO4 in water?

Same forms in both cases (ions and uncharged particles), different concentrations. To list all forms is not a problem. To calculate the concentrations... see here:

My recollection is that individual species are not included if they can recombine to form the salt.  C would be two in both cases: water and salt in an unsaturated solution.
