Methylene blue
Nope - methylene blue is a stain. You need liquid indicator like phenolphthalein that responds to pH changes.
Yes, methylene blue can be used in many foods, as it in non-toxic to humans (though it can discolor urine). Methylene blue was used by Italian actor and gourmand, Ugo Tognazzi for his risotto alla parmigiana (risotto blu). He added methylene blue to the standard ingredients (butter, onions, Parmesan cheese, and white wine), turning it into a rather striking "blue risotto."
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.
Staining Elodea and Anabaena cells with methylene blue can be useful in microscopy to enhance contrast and visualize cell structures more clearly. Methylene blue is commonly used as a general stain to highlight cellular components such as nuclei and cytoplasm. This staining technique can aid in identifying cellular organelles and structures during microscopic examination.
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 can be used to prepare slide for animal cells. For example, if you want to examine a piece of your cheek cell, you would take a piece of cotton wool and rub it on the inside of your cheek and the rub it on a microscope slide, the you add a little distilled water and then a drop of methylene blue. The final step you would take, is to cover the slide with a cover slip, then place it under the microscope.
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

A wet mount slide is typically used to view an Elodea leaf under a microscope. This type of slide allows the leaf to remain in a hydrated state, which is important for observing its cellular structure and processes.
Methylene blue
Methylene blue would enhance your observation more than iodide staining. Methylene blue binds to nucleic acids and proteins, making them more visible under a microscope. Iodide staining is primarily used for visualizing lipids in samples such as plant tissues.

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.
