2 years ago Correct. That only applies at 25°C when the autoionization constant of water, Kw, is equal to 1.0 x 10^ (-14). If we use Jay's example here at 50°C, then pH + pOH should equal ~13.28. Hope that helps. Comment ( 9 votes) As mass / volume = molarity × molar mass, then mass / (volume × molar mass) = molarity. Substitute the known values to calculate the molarity: molarity = 5 / (1.2 × 36.46) = 0.114 mol/l = 0.114 M. You can also use this molarity calculator to find the mass concentration or molar mass. Simply type in the remaining values and watch it do all Strong acids are H3O plus, HNO3, H2SO4, HCl, and HBr. Negligible acids are HS minus and OH minus. Stron bases are O negative 2, S negative 2. A Video Calculating pH in Strong Acid or Strong Base Solutions: Calculating pH in Strong Acid or Strong Base Solutions [youtu.be] Solutions of Strong Acids and Bases: The Leveling Effect. 2. When strong acids and weak bases react, they form salts that are acidic, calculating the pH using the pH hydrolysis formula where M = concentration of salt anion 3. If the remainder of the reaction results are a weak base remaining and the salt, the solution will form a base buffer solution and search for pH using the formula base buffer pH pH and pOH Calculations 1) Determine the pH of a 0.00340 M HNO3 solution. 2) Determine the pOH of a 0.00340 M HNO3 solution. 3) Determine the pH of a 4.30 x 10-4 M NaOH solution. 4) If a solution is created by adding water to 2.30 x 10-4 moles of NaOH and 4.50 x 10-6 moles of HBr until the final volume is 1.00 L, what is the pH of this solution? pH Calculator.
