I believe it means to worry about the entire planet but you should also help around your community. It applies the oceans having plastic in them because you can’t get all of the plastic out but you can pick trash around your city
Since HClO4 is a strong acid it will completely dissociate in solution.
HClO4 + H2O --> H3O+ + ClO4-
Therefore, your concentration of HClO4 will be equal to your amount of H3O+, the conjugate acid in solution.
The Ka expression is as follows:
Ka= [H3O+][ClO4-] / [HClO4]
So you know that -log [H3O+] gets you pH, so just plug in [2.2] as your concentration of H3O+ and your answer should be -.34 pH
