Calculating [H1] and pKa from the pH of a Solution of Weak Acid The pH of a 0.02 M solution of an acid was measured at 4.6. a. What is the [H+] in this solution? b. Calculate the acid dissociation constant Ka and pKa for this acid.

I'm learning about the periodic tables and what each subject's configuration is. for example, hydrogen is 1s^1, but i don't understand how you get that. can someone me understand how to figure out how to figure this out? sorry if the question makes no sense, but it would really a lot if you could me understand! you so much if you can!
