Ka of a weak acid HX is 6.72 × 10–7. During a titration, an analyte solution containing a mixture of [HX] and [X–] has the ratio of [X–]/[HX] = 1.75. What is the pH of the analyte solution? Assume the solution is in its buffering region, where pH of the solution can be approximated by: pH = pKa + log([X–]/[HX])

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
