A 0.050 M solution of the weak acid HA has [H3O+] = 3.77 × 10-4 M. What is the Ka for the acid b) 2.8 x 10-6 m.
What is a weak acid solution?
Weak acids are acids that do not dissociate completely in solution. A weak acid, in other words, is any acid that is not a strong acid. A weak acid's strength is determined by how much it dissociates: the more it dissociates, the stronger the acid.
Buffering Techniques
They are created by combining a weak acid with its conjugate base or a weak base with its conjugate acid.
In an aqueous solution or water, a weak acid partially dissociates into its ions. A strong acid, on the other hand, completely dissociates into its ions in water. A weak acid's conjugate base is a weak acid, while a weak acid's conjugate acid is a weak acid.
