After doing Ka calculations, you may wish you had an aspirin. Aspirin is a weak acid with Ka=3.27 x 10^-4 for the reaction. HC9H7O4(aq) + H2O(l) image from custom entry toolH3O(aq) + C9H7O4(aq) Two aspirin tablets, each containing .325 g aspirin(along with a nonreactive "binder" to hold the tablet together), are dissolved in 200.0 mL of water. Calculate the pH of the solution.
