I'm only given the pH (3.75) and the concentration (0.01M). Please, give me a couple of examples so I can use the precision to test what I'm doing. Thanks!
Should I Subtract this to get Ka?

3.75pH - 0.01M = 3.75

From the pH u can know it is a weak acid so we can use the law:
pH= pKa + pCa, where Ca is the concentration of the acid

so u can easily obtain pKa and Ka as u have pH and Ca
