The Ka for acetic acid (CH3COOH) is approximately 1.8 x 10^-5. This value represents the acid dissociation constant for acetic acid, indicating its strength as a weak acid. An acid with a higher Ka value will dissociate more readily in solution.

The absolute value of - 4 5/6 is 4 5/6.
The solution to this problem is simple if you just work backwards. pH= -log10[H+] You already know what your pH is, so write your equation like this: 4.3= -log10[H+] An understanding of basic logarithm properties lets you know that you can rewrite the equation like this: 10-4.3= [H+] 5.0 *10-5 = [H+]
It is 5/4
The value of 5 to the negative 4th power (5-4) is 0.0016

The pH of a solution is defined as -log10[H+]. Thus a solution with a hydrogen ion concentration of 10-5M has a pH of 5. [H+] = 10-5 pH = -log[H+] pH = - log [10-5] pH = 5
