1.Calculate the pH of 0.04M NaOH assuming complete dissociation of acid? Mcq
​

Answer 1

Answer:

Key Takeaways: pH of a Weak Acid

Finding the pH of a weak acid is a bit more complicated than finding pH of a strong acid because the acid does not fully dissociate into its ions.

The pH equation is still the same (pH = -log[H+]), but you need to use the acid dissociation constant (Ka) to find [H+].
