Question

a solution has ph of 5 to this 1 ml of dilute hydrochloric acid is added the ph of solution will be

Answer 1

You can calculate the H+ concentration by taking 10^(-pH), you now have the concentration of H+ in .001 L, diluting it to 2 L will use the equation M1V1=M2V2, 10^-5 *.001 is 10^-8, 10^-8 /2 = 5*10^-7, to get pH from this, you do -log([H+]), which is -log(5*10^-7), which gives a pH of 6.3.

Answer 2

the right answer is option A

more than 5
