Oxidation reaction is the loss of electrons
The substance that loses electrons is called the reducing agent or reductant
Reduction reaction is the gain of electrons
The substance that gains electrons is called the oxidizing agent or oxidant

08M Ammonium Oxalate (prepared with 1M H2SO4) were added into an
Erlenmeyer Flask and placed on the hot plate to be heated till 55oC
...
When the Ammonium Oxalate solution achieved the desired temperature, we began
titrating drop by drop slowly until the solution in the Erlenmeyer Flask started
turning light pink in colour
