Which substances are not ionized in a aqueous solution?
Hi, KBr, H2SO4, HNO2, AgCl, Ca(NO3)2
1 answer
All of them are ionized, at least partially. H2SO4 and HNO2 are not ionized completely. AgCl dissolves as a solid to form a solution in equilibrium between the solid and the undissociated aqueous solution and there is a Keq for that reaction. Then the solid solution ionizes to form the Ag^+ and Cl^- so there are two equilibrium constants for this one. I would choose AgCl as the answer to this question since this is the only one with an equilibrium constant between the solid and the undissociated solution. None of the others do this.
