Potassium permanganate dye diffuses more rapidly through water than agar gel. The rate of diffusion depends on the molecular weight of the chemical and the characteristics of the medium through which the substance diffuses.

Does potassium permanganate dye diffuse faster in water or an agar gel?
Potassium permanganate dye diffuses more quickly through water than agar gel.The rate of diffusion depends on the molecular weight of the chemical and the characteristics of the medium through which the substance diffuses.
Why does the purple colour spread when a crystal of potassium permanganate is placed in water?
A water solution of potassium permanganate is formed.
Why do Sodium and potassium ions do not diffuse in equal numbers through ligand-gated cation channels?
The inside surface of the sarcolemma is negatively charged compared to the outside surface. Sodium ions diffuse inward along favorable chemical andelectrical gradients.
Why pottasium permanganate solution kept for few days?
The permanganate solution has to cool and stand overnight before it can be filtered to remove MnO2 (manganese dioxide)Potassium permanganate is not a primary standard. It is difficult to obtain the substance perfectly pure and completely free from manganese dioxide. Moreover, ordinary distilled water is likely to contain reducing substances (traces of organic matter, etc.) which will react with the potassium permanganate to form manganese dioxide. The presence of the latter is very objectionable because it catalyses the auto-decomposition of the permanganate solution on standing. The decomposition:4MnO4- + 2H2O = 4MnO2+3O2+4OH-is catalysed by solid manganese dioxide. Permanganate is inherently unstable in the presence of manganese(II) ions:2MnO4-+3Mn2+ +2H2O = 5MnO2 + 4H+;this reaction is slow in acid solution, but is very rapid in neutral solution. For these reasons, potassium permanganate solution is rarely made up by dissolving weighed amounts of the highly purified (e.g., A.R.) solid in water; it is more usual to heat a freshly prepared solution to boiling and keep it on the steam bath for an hour or so, and then filter the solution through a non-reducing filtering medium, such as purified glass wool or a sintered glass filtering crucible (porosity No. 4).Alternatively, the solution may be allowed to stand for 2-3 days at room temperature before filtration. The glass-stoppered bottle or flask should bc carefully freed from grease and prior deposits of manganese dioxide: this may be done by rinsing with dichromate-sulphuric acid cleaning mixture and then thoroughly with distilled water. Acidic and alkaline solutions are less stable than neutral ones. Solutions of permanganate should be protected from unnecessary exposure to light; a dark-coloured bottle is recommended. Diffuse daylight causes no appreciable decomposition, but bright sunlight slowly decomposes even pure solutions.
Explain how a beam of light passing through a diffuse cloud may give rise to both absorption and emission spectra?
When a light passes through a diffuse cloud, part of the light will be reflected, part will be absorbed, and the rest will pass through depending on the density of the cloud and the energy of the light.The light's energy can be expressed by: E = h(Planck's constant)*nu(frequency)

Can Iodine Potassium Iodine when mixed with a starch diffuse through a semipermeable membrane?
yes
What is the reaction when light passes through potassium permanganate?
4 H3O(+) + 4 MnO4(-) ---> 4 MnO2 + 6 H2O + 3 O2
What is example of diffusion?
Tape a piece of wax paper over the window and it diffuses (spreads) the light. In the body: Oxygen molecules diffuse across cell membranes into cells, and carbon dioxide molecules diffuse out. Both compounds cross the phospholipid bilayer. In a non-living system: Place a small lump of sugar in a cup of tea (or just water). The sugar dissolves, then diffuses throughout the liquid. To see diffusion happening, use not sugar but a small crystal of potassium permanganate in water. The color will gradually disperse through the water.
Why do Sodium and potassium ions do not diffuse in equal numbers through ligand-gated cation channels?
The inside surface of the sarcolemma is negatively charged compared to the outside surface. Sodium ions diffuse inward along favorable chemical andelectrical gradients.
What substance will diffuse through a membrane?
The three substances that can diffuse through a cell membrane are CO2, O2, AND H2O.
Diffuse in a sentence?
Light will diffuse when it passes through frosted glass.
Which substances did not diffuse the membrane?
starch doesnt diffuse through the dialysis membrane.
Does albumin diffuse through a dialysis tube?
can protein (albumin) diffuse out of a dialysis tube and why
How do fish diffuse?
through osmosis
Why do sugar molecules not diffuse through a plant cell membrane?
The membrane is semi-permeable. Sugar molecules are too large to diffuse through.
