HO⁻ or Cl⁻

Determine the values of [H₃O⁺] and [OH⁻] for a solution with a pH of 8.92 at 25°C.

Consider the following solutions at 25°C. Fill out the missing information.

Three unknown bases were titrated. At the equivalence point, base A had a pH of 3.67, base B had a pH of 6.91, and base C had a pH of 4.28. Identify the strongest base and the weakest base.

The pH of a solution at 30.0°C is 5.60. The K_w at this temperature is 1.471×10^–14. Determine the [H⁺], [OH^–], and pOH for the solution.

Soda water is saturated with CO₂ at a partial pressure of 5.25 atm at 25°C. Calculate the pH of the soda water at 25°C given that Henry's law constant for CO₂ at this temperature is 3.1×10^–2 mol/L•atm. [H₂CO₃: K_a1 = 4.3×10^–7; K_a2 = 5.6×10^–11]
