Ph of rboh
WebAs the first step, we are going to calculate pOH value and then calculate the pH using the relationship of pH and pOH. Calculate pOH pOH = -log (OH -(aq)) pOH = -log ( 0.1) pOH = 1 Apply the relation of pH and pOH pH + pOH = 14 (at 25 0 C) pH + 1 = 14 pH = 13 Let's solve example 1 according to method 2. We know the concentration of OH - ions Web1. Strong acids are listed at the top left hand corner of the table and have Ka values >1 2. Acid with values less than one are considered weak.

WebA solution of rubidium hydroxide is prepared by dissolving 1.546g of RbOH in water to make up 0.500L of solution. The molar mass of RbOH is 102.475gmol−1. What is the pH of the solution at 25.0∘C? Round the answer to three significant figures. WebApr 10, 2024 · A pH of 12.4 indicates a pOH of 14-12.4 = 1.6. As pOH = -log [OH - ], the [OH -] is the antilog of - 1.6 = 0.0251 M/L. The number of grams of OH - required would be 0.0251 moles / L x 17.0 g/mole x 1L/1000 mL x 500 mL = 0.213 g OH -. The mass of KOH needed then is molar mass KOH / molar mass OH - x g OH -.
