Calculating pH Of Strong And Weak Bases Flashcards
1
Q
The more alkali a solution is…
A
The higher the concentration of OH- ions and smaller concentration of H+ ions
2
Q
What do we use to find the pH of strong bases?
A
The ionic product of water expression Kw
3
Q
Expression for Kw
A
Kw = [H+][OH-]
4
Q
How do we use the Kw expression to find pH of a strong base?
A
Find the conc of H+ ions!!!
Kw is constant at room temp so…
[H+] = Kw / [OH-]
pH = -log(H+)
