Molybdenum occurs naturally in various ores, the most important being molybdenite (MoS2), 

which is converted to molybdenum trioxide (MoO3) for use

in ferro- and manganese alloys, chemicals, catalysts, ceramics, and pigments.

Further, Mo–O connection appeared to exhibit both ionic (the charge transfer from 2p orbital of oxygen to molybdenum) and the covalent (charge accumulation in the region of Mo–O) components

N,N,N′,N′-tetramethyl-p-phenylenediamine dihydrochloride (TMPD) is an oxidizable compound that serves as a reducing co-substrate for heme peroxidases. It is also used as a test reagent in microbiology for the classification of cytochrome oxidase positive aerobic microorganisms.

Thymol blue (thymolsulfonephthalein) is a brownish-green or reddish-brown crystalline powder that is used as a pH indicator. It is insoluble in water but soluble in alcohol and dilute alkali solutions.        Thymol blue is used as a pH indicator. It transitions from red to yellow at pH 1.2–2.8 and from yellow to blue at pH 8.0–9.6. It is usually a component of Universal indicator (1).

N-bromosuccinimide (NBS) is used as a highly specific bromination agent both in free-radical 

substitutions and in electrophilic additions of unsaturated systems, because releases small quantities of bromine.

NBS is used as a substitute for Br2 in these cases since Br2 tends to react with double bonds to form dibromides. The advantage of NBS is that it provides a low-level concentration of Br2, and bromination of the double bond doesn't compete as much.

The primary use of DMF is as a solvent with low evaporation rate. ... It is a common solvent in the Heck reaction. It is also a common catalyst used in the synthesis of acyl halides, in particular the synthesis of acyl chlorides from carboxylic acids using oxalyl or thionyl chloride.

This compound is used as an ingredient in the manufacture of pesticides (such as thiocarbazides), pharmaceuticals, and emulsifiers.

 It is also a precursor for the manufacture of N,N′-dibutylthiourea, a rubber vulcanization accelerator, and n-butylbenzenesulfonamide, a plasticizer of nylon

Ninhydrin is most commonly used to detect fingerprints, as the terminal amines of lysine residues in peptides and proteins sloughed off in fingerprints react with ninhydrin. It is a white solid which is soluble in ethanol and acetone at room temperature.

The marker for a positive ninhydrin test is a deep blue colouration obtained in the solution. This reaction indicates the presence of amino acids, other amines and ammonia in the test sample.

One of the main uses of palmitic acid is in soaps because of its ability to help keep skin smooth. Palmitic acid is found in beeswax, which is a popular ingredient in personal care products. In cosmetics, palmitic acid is used in skin make-up to hide blemishes.

should be dissolved to prepare M/10 oxalic acid solution. 

On the other hand, 12.6 /4 = 3.15 g of crystals of oxalic acid should be dissolved in water and precisely 250 ml of the solution should be produced.

If anhydrous oxalic acid (COOH) is available then dissolve 4.5 g of the acid in one litre of distilled water to get 0.1 N oxalic acid solution. Add 13.16 g of NaOH (95% NaOH) in one litre distilled water and shake well.
