Though the term precipitate” sounds as if it may be raining in a beaker, a precipitate is just a solid that forms in a liquid remedy as an effect of a chemical reaction. In the event the reaction necessitates energy, it’s often indicated over the arrow. The volume of the end solution is 101 mL.
There are a lot of rules and techniques for balancing redox reactions, but basically all of them boil down to dealing with every one of both half-reactions individually. The perfect situation would be in case the huge bulk of the electrons created x-ray photons instead of heat. There wasn’t any typical method to assess the sum of precipitate in the cuvettes, and marking each of the cuvettes at standard intervals might have eliminated this error.
