Answer:

#pH=-log_10[H_3O^+]#

Explanation:

And given the logarithmic scale, #[H_3O^+]=10^(-pH)#.

See here for #pOH#.

Given the logarithmic scale, LOW and negative values of #pH# describe an highly acidic solution. In neutral water at #298K#, #pH=pOH=7#.

At temperatures higher than #298K#, how do you think #pH# would evolve?
