pH is a logarithmic scale used to indicate the hydrogen ion concentration, [H], of a solution: pH = -log[H+] Due to the autoionization of water, in any aqueous solution, the hydrogen ion concentration and the hydroxide ion concentration, [OH-], are related to each other by the K of water: K = [H+][OH-] = 1.00 × 10-¹4 where 1.00 x 10-14 is the value at approximately 297 K. Based on this relation, the pH and pOH are also related to each other as 14.00 pH + pOH Submit ✔ Correct Because the concentration had two significant figures, the pH has two digits after the decimal point. Part B 0.90 g of sodium hydroxide (NaOH) pellets are dissolved in water to make 8.0 L of solution. What is the pH of this solum Express the pH numerically to two decimal places.
