Since.......in concentration of solution is 0.01 ..
......so it PH will be 2..........(1)
............on using formula …
          Mv+mv=MV   
      : On putting value we get final concentration  
             : 0.001........ so final PH will be 3..........(2)
          :So,from eq(1)&(2) ........
               We get .....change in PH=1.
