Problem 78P

Determine the concentration of NO3− in each aqueous solution. (Assume complete dissociation of each compound.)

(a) 0.10M KNO3

(b) 0.10M Ca(NO3)2

(a) 0.10 M Cr(NO3)3

Step-by-Step Solution:
Step 1 of 3

Answer :

           (a) 0.10M KNO3

            KNO3K+  + NO3 -

            (0.10 M KNO3) x (1 mol NO3 {-} / 1 mol KNO3) = 0.1 M NO3{-} .

              (b) 0.10M Ca(NO3)2

              formula unit of calcium nitrate, Ca(NO3)2, contains

               one mole of calcium cations, 1×Ca2+

              two moles of nitrate anions, 2×NO−3

              This means that every mole of calcium nitrate that...
