Analytical Chemistry Question 266
Question: What is the concentration of nitrate ions if equal volumes of 0.1 M $ AgNO_3 $ and 0.1 M $ NaCl $ are mixed together
[NCERT 1981; CPMT 1983]
Options:
A) 0.1 N
B) 0.2 M
C) 0.05 M
D) 0.25 M
Show Answer
Answer:
Correct Answer: C
Solution:
$ M_1V_1\ =\ M_2V_2 $
$ 0.1\ \times \ V\ =\ M_2\ \times \ 2V $ Þ $ M_2=\frac{1\times V}{2V}=0.05M $
