SUMMARY
To prepare a 1.00 L solution with a pH of 5.42, the required mass of sodium bicitrate can be calculated using the formula [H3O+] = 10^-pH, which yields a hydronium ion concentration of approximately 3.72 x 10^-6 M. The equilibrium expression for the dissociation of sodium bicitrate must be established to find the necessary concentration of the compound. Understanding the relationship between pH and pOH is crucial, as pOH can be calculated using the formula pOH = 14 - pH, resulting in a pOH of 8.58.
