A 200ml of an acid soln of pH2.5 is converted nitra soln of pH is 3.7....
My answer is 3000 ml
PH 2.5 means concentration is 10-³×3.2.
PH 3.7 means final concentration is 10-⁴×2
so, by formula
M1V1 =M2V2
200×10-³×3.2=X×2×10-⁴
when u solve
X=3200ml
200ml water is initially present so, extra amount that is added is 3000ml.
hope my answer is correct
pls reply .
