Methylene blue is commonly used as a reducing agent in laboratory applications to visualize nucleic acids or proteins on gels. Iodine is utilized in starch tests to detect the presence of starch, as it forms a blue-black complex with starch molecules. Both are valuable reagents in specific laboratory procedures for identifying and visualizing certain compounds.
The reaction between potassium iodide and potassium bromide in the presence of methylene blue will result in the formation of elemental iodine (I2) which imparts a purple color to the solution. Initially, the reaction mixture will be colorless, but as iodine forms, the solution will turn purple.
Methylene blue will diffuse faster than potassium permanganate. Methylene blue has a smaller molecular size and a higher diffusion rate compared to potassium permanganate.
Methylene blue appears blue because of its molecular structure, which allows it to absorb light in the red-orange range of the visible spectrum and reflect or transmit light in the blue range. This selective absorption and reflection of light wavelengths give methylene blue its distinctive blue color.
Methylene blue is a synthetic dye that appears as a dark blue or greenish-blue color in its solid form. It is commonly used in biological staining techniques and as a medication for certain medical conditions.
Methylene blue discolouration measures the rate at which a material (usually soil) can reduce methylene blue dye. It is used to assess the dehydrogenase activity of microorganisms present in the material, providing an indication of soil microbial activity and overall soil health.
iodine
If methylene blue is blue, it means that the compound is in its oxidized state (methylene blue) and has accepted electrons. Methylene blue can exist in both oxidized (blue) and reduced (colorless) forms depending on its redox state.
To stain onion peel cells, you should use a stain called iodine. Iodine is commonly used to stain cells because it binds to starches and glycogen in the cells, making the cells more visible under a microscope.
A student can use a stain called methylene blue to make nuclei more visible under a microscope. Methylene blue is commonly used in biology and histology to stain cells and highlight structures like nuclei.
i think the methylene blue will be make aqua blue because the charcoal will penerate the color of methylene blue,,,there are absorption process,,,in the charoal between the methylene blue.... (kharlz)
The reaction between potassium iodide and potassium bromide in the presence of methylene blue will result in the formation of elemental iodine (I2) which imparts a purple color to the solution. Initially, the reaction mixture will be colorless, but as iodine forms, the solution will turn purple.
Methylene blue stains everything blue.
Tomato cells are stained with methylene blue because it binds to nucleic acids, allowing for visualization of the cell's nucleus and DNA content under a microscope. Iodine solution, on the other hand, is typically used to stain starch grains due to its ability to form a complex with starch molecules, rather than DNA.
you can get methylene blue powder from a scientific store, it comes in powdered form. its pretty soluble in water and alcohol etc. the stain is made by dissolving an appropriate amount on methylene blue in a solvent, e.g for 0.1 dissolve 0.1% gram of methylene blue in 100 gram water, for 9% dissolve 9 grams
because methylene blue turns colourless when it is reduced by hydrogen. during respiration hydrogen is produced and instead of reducing NAD, it reduces methylene blue and turns methylene blue colourless. if methylene blue goes from blue to colourless then this shows that the cell is respiring as it is producing a suffiecient amount of hydrogen to decolourise methylene blue
Methylene blue will diffuse faster than potassium permanganate. Methylene blue has a smaller molecular size and a higher diffusion rate compared to potassium permanganate.
