Equal volumes of 0.1 M AgNO3 and 0.2 MNaCI are mixed. The concentratio

1.	Equal volumes of 0.1 M AgNO3 and 0.2 MNaCI are mixed. The concentration of NOions in the mixture will be-(A) 0.1 M(C) 0.2 M(B) 0.05 M(D) 0.15 M
Answer» Let the volume of both the solution is 1 L. Total volume of the mixture after mixing = 2L Number of moles in 1L of NaCl solution = 0.2 Number of moles in 1L of AgNO3solution = 0.1 In solution [NO3-]= [AgNO3]= 0.1 After mixing [NO3-] = 0.1/2 0.05M option b

Equal volumes of 0.1 M AgNO3 and 0.2 MNaCI are mixed. The concentration of NOions in the mixture will be-(A) 0.1 M(C) 0.2 M(B) 0.05 M(D) 0.15 M

Answer»

Let the volume of both the solution is 1 L.

Total volume of the mixture after mixing = 2L

Number of moles in 1L of NaCl solution = 0.2

Number of moles in 1L of AgNO3solution = 0.1

In solution

[NO3-]= [AgNO3]= 0.1

After mixing

[NO3-] = 0.1/2

0.05M

option b
