Buffer pH
« on: March 14, 2006, 08:07:09 PM »
An initial buffer solution has a pH of 9.25 and .200M NH4Cl and .200M NH3. What is the pH after adding .0050 mol NaOH?

I think charts have to be made.

Thank you,

Sheryl

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

Assume NaOH reacted stoichiometrically with NH4+, the use Henderson-Hasselbalch equation using link Mitch posted ;)
