How to find the ph in a strong base weak acid titration?

Click For Summary
To find the pH at the equivalence point of a titration involving a strong base (NaOH) and a weak acid (nitrous acid), first determine the volume of NaOH needed, which is 0.01 L for this scenario. At the equivalence point, all the weak acid is converted into its conjugate base, resulting in a solution of sodium nitrite. The pH can then be calculated using the concentration of the conjugate base and its hydrolysis in water. The final pH will be greater than 7 due to the basic nature of the resulting solution. Understanding these steps is crucial for accurately determining the pH in such titrations.

Homework Statement


If .0200L of .100M nitrous acid is titrated using .200M NaOH solution, what will the pH be at equivalence?


Homework Equations





The Attempt at a Solution


I figured out that the volume of NaOH at equivalence is .01L, however I do not know what to do after that.

Thanks
