Methylene blue is used as an indicator for the presence of certain Ions such as the presence of HS - ion. spectrophotometry is used once the methylene blue has reacted to determine the quantity of said ion based on the intensity of blue that the reacion produces. Using a spectrophotometer you can determine the intensity and compare it with a set scale that has been calibrated with known concentrations of this ion.
To make the Eosin Methylene BLue Agar look cool and hip.
function of eosin methylene blue agar (EMB)
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, in this situation, is being used as a microscopy stain. Microscopy stains are used to allow for particular characteristics of cells to be observed in greater detail or to make them easier to see.
Methylene blue is an example.

Polluted water sample will decolorize the methylene blue solution faster than a pure water sample.
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)

Methylene blue stains everything blue.
The methylene blue will make the paramecium very horny and secrete sperm.
spectrophotometry is a branch of spectroscopy dealing with measurement of radiant energy transmitted or reflected by a body as function of wave lenght %
