A buffer solution is prepared in such a way that the concentration of propanoic acid is 1.8 x 10 M and the concentration of sodium propanoate is 1.9 x 10° M. The buffer equilibrium is described by Guic C,H;COOH(aq) + H2O(1) =H,o*(aq) + C,H3CO0aq) propanoic acid propanoate ion with K 1.34 x 10P. If the concentration of the sodium propanoate were doubled while the acid concentration remained the same, calculate the pH of the resulting solution. pH =
