An unknown weak acid with a concentration of 0.530 M has a pH of 5.600. What is the Ka of the weak acid

Ka = 3.45x10⁻⁶

Explanation:

First we calculate [H⁺], using the given pH:

To solve this problem we can use the following formula describing a monoprotic weak acid:

We input the data that we already know:

And solve for Ka:
