Problem
A buffer solution is prepared by mixing 0.10 mol of HF with 0.15 mol of KF in enough water to make 500 mL of solution.
To test students’ understanding of ionic versus net ionic representations, a teacher adds 10.0 mL of 2.0 M HNO3 to the buffer.
(a) Write the complete (full) ionic equation for the reaction that occurs immediately after the acid is introduced, including all spectator ions.
(b) Derive the corresponding balanced net ionic equation.
(c) Identify the spectator ions and explain why they do not appear in the net ionic equation.
