Some Basic Concepts Of Chemistry Question 239
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:
0.1 M $ AgNO _3 $ will react with 0.1 M NaCl to form 0.1 M $ NaNO _3 $ . But as the volume is doubled, conc. of $ NO_3^{-}=\frac{0.1}{2}=0.05,M $
