Question
How many grams of acetic acid must be dissolved to produce 3875 ml with a Ph of 2.9?
Answers
pH = 2.9 = -log(H^+)
Solve for (H^+) = 0.00126M
........HAc ==> H^+ + Ac^-
E.......x..0.00126..0.00126
Ka = (H^+)(Ac^-)/(HAc)
Substitute and solve for (HAc).
grams = mols x molar mass
g/L x 3.875 L = g/3875 mL.
