Web(d) H2SO3: H2SO3 is also a weak acid, and it partially dissociates in water as follows: H2SO3 ⇌ H+ + HSO3-The equilibrium constant for this reaction is Ka = [H+][HSO3-]/[H2SO3]. The Ka value for H2SO3 is 1.6 x 10^-2. To calculate the pH of a 0.0400 M solution of H2SO3, we can use the equilibrium expression and the quadratic formula: WebSo, if we plug in our pOH into here, pH is equal to 14.00 minus 5.33, which is 8.67. So, we're at the equivalence point, but this is a titration of a weak acid with a strong base. And so, we have a basic salt solution at the equivalence point. So, our pH is in the basic range. It's above seven. So, let's find that point on our titration curve.
WebJan 30, 2024 · The equation to find the pH of a solution using its hydronium concentration is: pH = − log(H3O +) Using this equation, we find the pH of pure water to be 7. This is considered to be neutral on the pH scale. The pH can either go up or down depending on the change in hydronium concentration.
