What does the pH of a solution indicate? As the hydronium ion concentration of a solution increases, does the pH of the solution increase or decrease?

Answer 1

#pH=-log_10[H_3O^+]#

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?

The pH of a solution indicates its acidity or basicity. A lower pH indicates greater acidity, while a higher pH indicates greater basicity. As the hydronium ion concentration of a solution increases, the pH of the solution decreases.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
