Rank the following substances in order of [H3O+]. Assume each has a concentration of 0.200 M. KOH:  [a] NH4Br:  [b] HNO3:  [c] C5H5N:  [d] NaCl: [e]

The pH of two separate solutions, 1.0 M HNO3 and 1.0 M HC2H3O2, are measured. Which statement is true?

Equal volumes of 0.50 M HBr and 0.5 M NH3 are mixed together. The resulting solution can be best described as [desc]. Why? [why]

Which sets of units could represent the units on a second order rate constant?

Using provided data, determine

The reaction shown is at equilibrium. If a student adds more X to the system, what happens immediately (at that instant) to Q and K? X + Y
