What are the molar concentrations of the ions in a 0.20 M calcium nitrate, Ca(NO 3 )

Question:

What are the molar concentrations of the ions in a 0.20 M calcium nitrate, Ca(NO3)2, solution?

Strategy

In aqueous solution, Ca(NO3)2 dissociates into one Ca2+(aq) and twoNO3 (aq) ions.

Ca(NO3)2(s)- HO Ca+(aq) + 2NO3(aq)

Use the coefficients for Ca(NO3)2, Ca2+(aq), andNO3 (aq) to calculate the Ca2+(aq) and NO3 (aq) concentration.
