Nessler's reagent is used to detect ammonia. It is a pale solution which gets darker yellow when some amount of ammonia is added. A brown precipitate may form at higher concentration. Nessler's reagent can be crystallized from a concentrated solution of mercury iodide with potassium iodide.

NESSLERS REAGENT KINGS For determination of serum urea nitrogen the Nessler chemical reagent may cause additional turbidity when At present, the detection methods of ammonia nitrogen in aquaculture water 

Nigrosin stain, 10% w/v is used as staining solution for negative staining. ... Nigrosin consists of a suspension of fine particles of carbon. These form a dark background, against which capsules are clearly seen as a result of displacement of the carbon particles.

In medicine, Patent Blue V is used in lymphangiography and sentinel node biopsy as a dye to color lymph vessels. It is also used in dental disclosing tablets as a stain to show dental plaque on teeth. The color of the dye is pH-dependent.

A synthetic dye with imaging and food coloring property. It is a sodium or calcium salt of [4-(alpha-(4-diethylaminophenyl)-5-hydroxy- 2,4-disulfophenyl-methylidene)-2,5-cyclohexadien-1-ylidene] diethylammonium hydroxide inner salt

Pentanes are some of the primary blowing agents used in the production of polystyrene foam and other foams. Usually, a mixture of n-, i-, and increasingly cyclopentane is used for this purpose. Acid-catalyzed isomerization gives isopentane, which is used in producing high-octane fuels.

Para-anisidine is a reagent that reacts with aldehydes to give products that absorb at 350 nm (Fig. 7.5). The p-anisidine value is defined as the absorbance of a solution resulting from the reaction of 1g fat in isooctane solution (100 ml) with p-anisidine (0.25% in glacial acetic acid).

Red litmus paper is a base indicator. It turns blue at 8.1 pH and higher. While not a measure of pH levels, it's a quick and accurate way to determine if a solution is alkaline.

1. Light-blue litmus paper turns red under acidic conditions, and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at 25 °C (77 °F).

Mercury is rarely found in nature as the pure, liquid metal, but rather within compounds and inorganic salts. 

Elemental mercury is a shiny, silver-white metal that is a liquid at room temperature and is traditionally used in thermometers and some electrical switches.

Malachite green also is used as a direct dye for silk, wool, jute, and leather and to dye cotton that has been mordanted with tannin. Prepared from benzaldehyde and dimethylaniline, the dye occurs as lustrous green crystals soluble in water and in alcohol.      However, the dye has generated much concern regarding its use, due to its reported toxic effects. The toxicity of this dye increases with exposure time, temperature and concentration.

Methanol, also known as methyl alcohol or methyl hydrate, amongst other names, is a chemical and the simplest alcohol, with the formula CH3OH (a methyl group linked to a hydroxyl group, often abbreviated MeOH). It is a light, volatile, colourless, flammable liquid with a distinctive alcoholic odour similar to that of ethanol (potable alcohol).
