[Cl^(-)] in a mixture of 200mL of 0.01 M...

`[Cl^(-)]` in a mixture of 200mL of 0.01 M HCl and 100 mL of 0.01 M `BaCl_(2)` is

A

0.01M `NaHCO_(3)^(-)`

B

0.0133M

C

0.03M

D

0.02M

Text Solution

Verified by Experts

The correct Answer is:
B
`BaCl_(2) rarr Ba^(2+)+2Cl^(-)` ltbr. `[Cl^(-)]` in 0.01 M `BaCl_(2)=0.02 M`
`[Cl^(-)]` in the mixture `=(200xx0.01 +100xx0.02)/(300)` ,brgt `=0.0133M`
