Is it possible to measure a liquid's pH level and acidic level through the surrounding air molecules? Or is a direct sample necessary for accurate measurement?

Thanks for your *delete me*

Generally, pH is defined only for a solution.  How you're going to sample enough mist or moisture from the air around the solution is hard to visualize in any case.  Can you tell us some more about your needs.
