1. Homework Statement
What mass of sodium bicitrate would be needed to prepare a 1.00 L solution with a pH of 5.42?


2. Homework Equations
[H30+]=10^-pH


3. The Attempt at a Solution
First of all, I don't know what sodium bicitrate is, so I can't write the equation for it. What's bicitrate?

I wanted write the equilibrium expression for Ka. But I can only find the concentration of the [H30+] and not anything else... I have no idea how to do this question. Help please?
