What is the Ka of a weak acid?
Ka is the equilibrium constant for the dissociation reaction of a weak acid. A weak acid is one that only partially dissociates in water or an aqueous solution. The value of Ka is used to calculate the pH of weak acids. The pKa value is used to choose a buffer when needed….

Is there a ka for iodous acid HIO2?
Finding a Ka for HIO2. Iodous acid, HIO2, is a weak acid. A 0.0215M solution of iodous acid has a pH of 5.37. What is Ka for HIO2. I set up and ice table, but am not sure that I actually wrote the reaction equation correctly.
What is the Ka value for an acid HA?
For an acid HA: At the halfway point on an equivalence curve, pH = pK a . Helmenstine, Todd. “Table of Common Ka Values for Weak Acids.”
When to use ka or pKa for weak acids?
A weak acid is one which only partially dissociates in water or an aqueous solution. The value of Ka is used to calculate pH of weak acids. The pKa value is used to choose a buffer when needed. Choosing an acid or base where pKa is close to the pH needed gives the best results.
How is the pkavalue related to pH and Ka?
The pKavalue is used to choose a bufferwhen needed. Choosing an acid or base where pKais close to the pHneeded gives the best results. Relating pH, Ka, and pKa pH, Ka, and pKaare all related to each other. For an acid HA: Ka= [H+][A-] / [HA]pKa= – log KapH = – log([H+]) At the halfway point on an equivalence curve, pH = pKa.
