One Ka → monoprotic acid
let HA → barbituric acid
Equilibrium reaction: HA(aq) + H2O(l) ⇌ A-(aq) + H3O+(aq)
Step 1: Construct an ICE chart for the reaction.
Step 2: Write the Ka expression.
Solids and liquids are not included in the expression
Step 3: Calculate the equilibrium concentrations.
Calculate the pH at the following point in a titration of 40 mL (0.040 L) of 0.100 M barbituric acid (Ka = 9.8 × 10−5) with 0.100 M KOH.
(a) no KOH added
