Charles Darwin is generally credited with developing the concept of

What is the pH of the resulting solution if 25.00 mL of 0.10 M acetic acid is added to 10.00 mL of 0.10 M NaOH? Assume that the volumes of the solutions are additive. Ka = 1.8 × 10-5 for CH3CO2H

A 25.0 mL sample of 0.150 M hydrofluoric acid is titrated with a 0.150 M NaOH solution. What is the pH at the equivalence point? The Ka of hydrofluoric acid is 3.5 × 10-4.

Based on your prior understanding of equilibrium (Le Chatelier’s principle) explain why the percent ionization of a weak acid decreases as the concentration of the acid increases. Hint: think of the dissociation equilibrium of a weak acid, HA:

Calculate the concentration of H3O⁺ in a solution that contains 5.5 × 10-5 M OH⁻ at 25°C.  Identify the solution as acidic, basic, or neutral.

The following reaction is exothermic.  Which change will shift the equilibrium to the left?             2 SO2(g) + O2(g)  ⇌  2 SO3(g)

The water pressure to an apartment is increased by the water company. The water enters the apartment through an entrance valve at the front of the apartment. Where will the increase in the static water pressure be greatest when no water is flowing in the system?
