The sediment of a lake-its muddy bottom layer-contains relatively high concentrations of nitrogen and phosphorus. These can be released to water, particularly under conditions of low oxygen concentrations. The nutrients in the sediment come from the past settling of algae and dead organic matter.
Potassium permanganate is an inorganic chemical compound with the chemical formula KMnO 4. It is a salt consisting of K+ and MnOâ 4 ions. Formerly known as permanganate of potash or Condy's crystals, it is a strong oxidizing agent.It dissolves in water to give intensely pink or purple solutions, the evaporation of which leaves prismatic purplish-black glistening crystals.In 2000, worldwide production was estimated at 30,000 tonnes.Using sodium hydroxide the end product is not sodium manganate but an Mn(V) compound which is one reason the potassium permanganate is more commonly used than sodium permanganate. Furthermore the potassium salt crystallizes better).
Compute the rate of diffusion of the potassium permanganate molecules in millimeters per minute as well as the rate of methylene blue. Prepare the lab report together with your introductions, hypothesis, discussions, results, conclussions, and then the references.
