Answer:

#pH# = 5.08

Explanation:

The pH can be obtained directly from the concentration using the formula below:

Take the -logarithm of the concentration of hydronium ions that are in the solution:

#pH = -log (8.4xx10^(-6)M) = 5.08#

#color(blue)("Note")#: #H_3O^(+)# is the same as #H^(+)#. This is because we're assuming that water molecules interact with #H^(+)# in solution.
