Homework Statement
A 100.0mL buffer solution is 0.175M in HClO and 0.150M in NaClO.
Find the pH of the solution.
Homework Equations
Ka=10^-pH
([H30+][A-])/([HA])
-log([H30+]) = pH
The Attempt at a Solution
[HClO] [H3O+] [ClO-]
I .175 0 .150
C -x +x +x
E .175-x x .150+x
([x][.150+x])/([.175-x])
([x][.150])/([.175]) (assuming x is small)
This is where I'm stuck; having neither a pH nor Ka/Kb values. The homework is setup in such a way that we aren't expected to find known values from outside sources and none are provided in the text or in any previous problem sets. Because of this I'm assuming that there should be a way to find the hydronium concentration and/or the Ka, but I can't figure out how.
