To a `10mL` of `10^(-3) N H_(2)SO_(4)` solution water has been to make the total volume of one litre. Its `pOH` would be `:`

A

3

B

12

C

9

D

5

Text Solution

Verified by Experts

The correct Answer is:
3

`N_(1)V_(1)=N_(2)V_(2)`
`10^(-3)xx10=N_(2)xx1000`
`rArrN_(2)=10^(-5)`
`:. pH=5`
and `pOH=14-5=9`

4.0 g of monobasic, saturated carboxylic acid is dissolved in 100 mL water and its 10 mL portion required 8.0 mL 0.27 M NaOH to reach the equivalence point. In an another experiment, 5.0 g of the same acid is burnt completely and CO_(2) produced is absorbed completely in 500 mL of a 2.0 N NaOH solution. A 10 mL portion of the resulting solution is treated with excess of BaCl_(2) to precipitate all carbonate and finally titrated with 0.5 N H_(2)SO_(4) solution. Determine the volume of the acid solution that would be required to make this solution neutral.
