What is the value of equilibrium constant kw KW at 25 C?
In the autoionization of water, a proton is transferred from one water molecule to another to produce a hydronium ion (H₃O⁺) and a hydroxide ion (OH⁻). The equilibrium expression for this reaction is Kw = [H₃O⁺][OH⁻], where Kw is the autoionization constant for water. At 25°C, the value of Kw is 1.0 x 10⁻¹⁴.

What is the pH of pure water at 40.0 C if the Kw at this temperature is 2.92 x10 14?
To calculate the pH of pure water at 40 degrees Celsius, we need to know the concentration of hydrogen ions and oxygen ions in the solution. The hydrogen ion concentration is 2.92 x 10-14 moles/liter, while the oxygen ion concentration is 0.10 moles/liter. Therefore, the pH of pure water at 40 degrees Celsius is 7.41.
