Some Basic Concepts Of Chemistry Question 164
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 [CPMT 1983; NCERT 1985]
Options:
A) 0.1 M
B) 0.2 M
C) 0.05 M
D) 0.25 M
Show Answer
Answer:
Correct Answer: C
Solution:
0.1M $ AgNO _3 $ will react with 0.1M NaCl to form $ 0.1M\ NaNO _3 $ . But as the volume doubled, conc. of $ NO_3^{-}=\frac{0.1}{2}=0.05M $ .
