Question 5 a solution is prepared at 25°c that is initially 0.35m in chlorous acid hclo2, a weak acid with =ka×1.110−2, and 0.29m in sodium chlorite naclo2. calculate the ph of the solution. round your answer to 2 decimal places.

Answer : The pH of the solution is, 1.88

Explanation : Given,

Concentration of = 0.35 M

Concentration of = 0.29 M

First we have to calculate the value of .

The expression used for the calculation of is,

Now put the value of in this expression, we get:

Now we have to calculate the pH of the solution.

Using Henderson Hesselbach equation :

Now put all the given values in this expression, we get:

Therefore, the pH of the solution is, 1.88

pure substance: iron,copper

impure substance: water,charcoal

the answer is minerals.
