how do you find PH of 0.010 M HNO3 solution?
pH=-log(H3O+)=-log(0.01)=2
HNO3 is a strong acid meaning that it ionizes 100%.
pH = -log(H^+) = -log(0.01) = ??
To find the pH of a 0.010 M HNO3 solution, we need to use the formula for pH. pH is defined as the negative logarithm to the base 10 of the hydrogen ion concentration ([H+]).
In this case, we need to find the concentration of [H+] in the 0.010 M HNO3 solution. However, it's important to note that HNO3 is a strong acid, which means that it dissociates completely in water to produce H+ ions.
We can assume that the HNO3 completely dissociates into H+ and NO3- ions:
HNO3 -> H+ + NO3-
Therefore, the concentration of [H+] in the solution will be equal to the concentration of HNO3, which is 0.010 M.
Now, we can use the formula for pH:
pH = -log[H+]
Substituting the value of [H+] into the formula, we get:
pH = -log(0.010)
Using a scientific calculator, -log(0.010) is equal to 2.
So, the pH of the 0.010 M HNO3 solution is 2.
To find the pH of a solution, you need to know the concentration of H+ ions in that solution. In the case of a strong acid like HNO3, it completely dissociates in water, which means that all of the HNO3 molecules break apart into ions.
To determine the concentration of H+ ions in a 0.010 M HNO3 solution, we can assume that the concentration of H+ ions is also 0.010 M since every HNO3 molecule dissociates to release one H+ ion.
Now, to calculate the pH of this solution, you can use the equation:
pH = -log[H+]
Substituting the value of [H+] in the equation, we get:
pH = -log(0.010)
Using a calculator, you can find that the pH of a 0.010 M HNO3 solution is 1.
