Th pH of 0.00010 M HNO3
pH = -log(H^+) = -log(0.00010) = ??
PH HNO3 0.00010M
To find the pH of a solution, you need to know the concentration of the hydrogen ions (H+) in the solution. In the case of nitric acid (HNO3), it dissociates completely in water, so each molecule of HNO3 produces one hydrogen ion (H+).
Given that the concentration of HNO3 is 0.00010 M, the concentration of H+ in the solution is also 0.00010 M.
The pH of a solution can be calculated using the equation:
pH = -log10[H+]
Plugging in the concentration of H+ in the equation, we get:
pH = -log10(0.00010)
Using a scientific calculator or online calculator, you can find that the log10 of 0.00010 is -4. Therefore:
pH = -(-4) = 4
So, the pH of a 0.00010 M HNO3 solution is 4.
