Which of the following acids (listed with ka values) and their conjugate base would form a buffer with a ph of 2.34? a. hf, ka = 3.5 x 10-4 b. c6h5cooh, ka = 6.5 x 10-5 c. hclo2, ka = 1.1 x 10-2 d. hclo, ka = 2.9 x 10-8 e. hio3, ka = 1.7 x 10-1

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution
