Answer:

The concentration of
H^+ ions in the solution is
1.778* 10^(-4) M.

Step-by-step explanation:

The pH of the solution is defined as negative logarithm of
H^+ ion concentration.


pH=-\log[H^+]

The pH of the nitric acid solution = 3.75


3.75=-\log[H^+]


[H^+]=Antilog [-3.75]=0.0001778=1.778* 10^(-4) M

The concentration of
H^+ ions in the solution is
1.778* 10^(-4) M.
