What is the concentration of nitrate ions if equal volumes of 0.1 M AgNO3 and 0.1 M NaCl are mixed together
A
0.1 N
B
0.2 M
C
0.05 M
D
0.25 M
Answer:
The correct option is B. 0.2 M
Note
0.1 M AgNOA will react with 0.1 M NaCl to form 0.1 M NaNOA.
But as the volume is doubled, conc. of NO–3 = (0.1)(2)
= 0.05 M
