100 mL of M 10 Ca ( NO ₃ )₂ and 200 mL of M 10 KNO ₃ solutions are mixed. What is the normality of resulted solution with respect to NO ₃⁻ ?

Step-by-step solution

We know that Normality = Molarity Z factor N ₁= 1 10 2= 1 5 N ₂= 1 10 1= 1 10 no. of mole ( n ₁ )= 1 5 100=20 mole no. of mole (n₂ )= 1 10 200=20 mole Total mole ( n ₁+ n ₂ )=40 ~mole Concentration/Normality of solution = n₁+n₂ v₁+v₂ = 40 300 =0.13 ~N
