A student is analyzing the pH of a solution and finds that the pOH is 4.25 at 25°C.
Using the ionization constant of water (Kw), determine the pH of the solution and explain why pH + pOH = 14 at this temperature.
i) Calculate the pH of the solution using your answer from part (a). Show all working.
ii) Identify whether the solution is acidic, basic, or neutral based on your answer from part (i). Justify your answer by comparing the pH to 7.
If the temperature increases above 25°C, predict how the pH of pure water will change. Justify your answer.
