Determine [H3O+] of a 0.226 M solution of benzoic acid (for which Ka=6.5×10−5 ).Determine the pH of this solution of benzoic acid.

2a) Write the hydrolysis reaction of a 0.050M solution of hydrochloric acid. Clearly identify the acid, base, conjugate acid, and conjugate base in the reaction. b) is this acid a strong acid or weak acid? Why? c) calculate the [H3O+] for this reaction d) calculate the pH of a 0.050M solution of this acid

Consider the following data on some weak acids and weak bases: acid base Ka name formula name formula HCH3CO2 1.8 × 10 C,H;NH, 4.3 × 10 5 10 acetic acid aniline hydrofluoric acid HF 6.8 x 10 ethylamine C2H;NH2| 6.4 x 10 Use this data to rank the following solutions in order of increasing pH. In other words, select a 'l' next to the solution that will have the lowest pH, a '2' next to the solution that will have the next lowest pH, and so on. solution pH 0.1 М KF choose one 0.1 M C2H5NH3CI choose one 0.1 M NaCl choose one 0.1 M NaCH3CO2 choose one

If 7.1 g of butanoic acid, C₂H₂ O₂, is dissolved in enough water to make 1.0 L of solution, what is the resulting pH? Look up the K₁ value in the Table of Ionization Constants. pH =
