find out the pH of a solution obtained by mixing 2l h2so4 solution of pH 3

Hi,

I am not clear that you want to know pH when 2l ,H2SO4solution of  pH 3 is mixed with some other solution having a different pH.

Or

You want to know what is the resultant pH when 2l H2SO4 solution is mixed with a solution of pH3.

So instead of telling exact solution I would like to let you know the method how to calculate pH of solution when two solutions of different pH are mixed.

Consider that you have mixed 1L h2so4 solution with 1L solution having pH 3. You have a resultant solution of 2L whoose pH you want to know. So to find out the pH of a solution follow the steps given.

Step 1: calculate the concentration of H+ ions in solution one ,for example of 1l h2so4 solution.

Step 2: calculate the concentration of second solution for example solution of pH3.

Step 3: calculate the concentration of resultant 2L solution. To do so add

Concentration of H+ ion  in h2so4solution  + concentration of H+ion in solution of ph3

Then

Divide your answer with volume of resultant solution here in example we have 2L of volume. So divide by 2. The answer will be H+ion concentration of resultant solution.

Now the task is simple ,we know that

pH= -log (H+)

Put the values in the formula and you will find out the ph of the resultant solution.

Though I can not provide you exact solution but I am sure by following above steps you would become able to calculate the pH of a solution when two solution of different pH are mixed.

Hope you like this information.
