QAIPMT-2009-Ch-2136: NEET 2009 Chemistry - Class 11 AIPMT-2009-Ch-2136 Solution: What is the \([OH^-]\) in the final solution prepared by mixing …
What is the in the final solution prepared by mixing 20.0 mL of 0.050 M HCl with 30.0 mL of 0.10 M ?
Multiple Choice Options
- A 0.40 M
- B 0.0050 M
- C 0.12 M
- D 0.10 M
Step-by-Step Verified Solution
Number of equivalents of
H + = 20.0 _ 0.050 milliequivalents
= 1.0 milliequivalents
Number of equivalents of OH �
= 2 _ 30.0 _ 0.10
= 6.0 milliequivalents
_ Equivalents of OH -
left after neutralization
= 6 � 1 = 5 milliequivalents
Total volume after neutralization
= 20.0 + 30.0 mL
= 50 mL
[OH - ] = 5 50 = 0.1 M
