Given that the pKabH of a weak base is 4.7, and given that Keq for the reaction between the weak base and a weak acid is 2.3 LaTeX: \times×10-6 (see below), what is the pKaHA of the weak acid? Enter your answer to the nearest tenth. Assume the temperature is 25 °C. Also, the value of R, the gas constant, is 1.987 cal/KLaTeX: \cdot⋅mol.
