WebbThe concentration of H 3 O + in a solution can be expressed as the pH of the solution; pH = −logH 3 O +. The concentration of OH − can be expressed as the pOH of the solution: pOH = −log [OH − ]. In pure water, pH = 7.00 and pOH = 7.00 Key Equations pH = −log [H 3 O +] pOH = −log [OH −] [H 3 O +] =10 −pH [OH −] =10 −pOH WebbStrong acids (such as HCl, HBr, HI, HNO₃, HClO₄, and H₂SO₄) ionize completely in water to produce hydronium ions. The concentration of H₃O⁺ in a strong acid solution is therefore equal to the initial concentration of the acid. For example, a solution of 0.1 M HNO₃ contains 0.1 M H₃O⁺ and has a pH of 1.0. Created by Jay. simon oforiWebb27 mars 2024 · From the value of p H we can easily calculate the p O H using the equation p H + p O H = 14. As we know that p O H = 14 − p H p O H = 14 − 4.5229 = 9.47 So the answer is A. Note: p H is a scale used to specify the acidity or basicity of an aqueous solution.

Webb16 mars 2024 · The pOH is a similar measurement to the pH and correlates to the concentration of hydroxide ions in a solution. The formula for the pOH is: pOH = -log10 ( … WebbFor dilute (ideal) solutions, the standard state of the solute is 1.00 M, so its molarity equals its activity. That's why for most problems that assume ideal solutions we can use the base 10 logarithm of the molar concentration, not the activity. Why do we need pH at all? pH is a measure used to specify acidity or basicity of an aqueous solution.

Webb24 jan. 2016 · I think the point that you have forgotten is that both H+ (rather H3O+) and OH- exist together in solution although one might be in excess of the other. So your first approach is more suitable. pH is by definition the negative of the common logarithm of total H+ concentration in the solution. WebbSince we have the pOH, we could use the pOH equation to find the concentration of hydroxide ions in solution. So we would just need to plug in the pOH into this equation …
