Question

0.22 L of HNO3 is titrated to equivalence using 0.18 L of 0.2 MNaOH. What is the concentration of the HNO3?

Answer 1

0.16 M

Step-by-step explanation:

Data provided as per the question is below:-

Volume of
`HNO_3` = 0.22 L

The Volume of NaOH = 0.18 L

Morality of NaOH = 0.2

According to the given situation, the calculation of the concentration of the
`HNO_3` is shown below:-

For equivalence,

Number of the equivalent of
`HNO_3` = Number of equivalents of NaOH

`= (0.18*0.2)/(0.22)`

`= (0.036)/(0.22)`

= 0.16363 M

or

= 0.16 M
