Answer:
pH = 3; acidic
Explanation:
The equation to find pH given [H+] is:
pH = -log[H+]
In the question it gives us the concentration of [H+], which is 0.0010 M.
Now just plug this into the equation to solve:
pH = -log(0.0010)
pH = 3
This would make the solution acidic as it is less than 7.
Hope this helps!!
