What Ka is 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.

What is the formula of Iodous acid?

iodous acid/Formula

What is the formula for iodic acid?

Iodic acid/Formula

How do you find the Ka of acetic acid?

Dissociation Constant for Acetic Acid Since x = [H3O+] and you know the pH of the solution, you can write x = 10-2.4. It is now possible to find a numerical value for Ka. Ka = (10-2.4)2 /(0.9 – 10-2.4) = 1.8 x 10-5.

What is Ka of strong acid?

Strong acids completely dissociate in aq solution (Ka > 1, pKa < 1).

What is the Ka of iodous acid (HIO2)?

$\\begingroup$ There is a question posted on the Q&A site CheggStudy that reads: “Determine the pH of a 50 mL solution of a 0.15 M iodous acid (HIO2). The Ka of iodous acid is 2.9×10−5. “.
