If you used acid-alcohol as the decolorizing agent in spore staining the cells of the bacillus are gram plus. If you use acid alcohol it will not decolorize gram plus cell wall as only gram negative are decolorized. It will not get a differentiation in color.
Assume that during the performance of this exercise you made several errors in your spore-staining procedure. In each of the following cases indicate how your microscopic observations would differ from those observed when the slides were prepared correctly . A. you used acid-alcohol as the decolorizing agent . B. you used safranin as the primary stain and malachite green as the counterstain C. you did not apply heat during the application of the primary stain · A. Normally tap water is used as the decolorizing agent to wash off excess stain. When you use acid-alcohol, it decolorizes the cells and the stain is removed. · B.When you use safranin as the primary stain and malachite green as the secondary stain, the cells will stain green and the spores will stain red. · C.When heat is not applied during the application of the primary stain, the spores are not stained and they appear colorless.
Probably not. The CVI complex formed between the iodine and crystal violet will be trapped in the lipid layer and not the peptidoglycan layer, so you would probably end up over decolorizing. This would cause a lot of false gram negatives. Probably not.

The Gumamela flower can be used as a shoe blackening agent. The juice itself from the petals is used for the agent and can also be used in mascara.
The decolorizer, usually acetone or alcohol, is used to wash the Crystal Violet stain from the Gram Negative cells. From this point Safranin stain is used to stain the Gram Negative cells. The final color for Gram Negative will be a Red/Pink color.
Water removes (decolorizing agent) the Malachite green from all parts of the bacteria excluding the spore. The spore appears green when examined.
The decolorizing agent in the acid fast stain is acid alcohol. The decolorizing agent in the gram stain is ethanol.
Alcohol is a term used for any O-H group that is attached to a carbon. Perhapes the alcohol is found in a Safranin stain. I hope I have this right but if alcohol was used as the decolorizing agent, it may wash out too much stain to get a good view in an oil emersion microscope.

Why fluorine and chlorine act as decolourizing agents? Answer : They can oxidize dyes to colorless substances. Litmus and universal indicators can be decolorized. Chlorine is used in the bleaching powder which bleaches the substances due to oxidizing capabilities of chlorine.
Agent Orange was used in Okinawa.

The copper sulfate is used as a decolorizing agent rather than water. The copper sulfate washes the purple primary stain out of the capsular material without removing the stain bound to the cell wall. At the same time, the decolorized capsule absorbs the copper sulfate, and the capsule will now appear white in contrast to the deep purple of the cell.
was agent orange used at fort polk la.
yes, it is a drying agent
The most critical step of gram staining is the decolorization step as crystal violet stain will be removed from both G+ve & G-ve cells if the decolorizing agent(e.g alchohol ) is left on too long.
The pure compound is colorless, but older samples tend to acquire a yellow Nitric acid is also commonly used as a strong oxidizing agent.
