10mL of an aqueous solution containing 0.020 M RCOOH (pKa = 6.00) is mixed with 10mL of CCI4. The partition coefficient is 3.0. When the pH of the aqueous phase is adjusted to 6.00, 0.012 M of RCOOH is measured in the CCL4 phase. What will be the formal concentration of RCOOH in the aqueous solution if its pH was adjusted to 7.00 before extraction?
