Chemiluminescence in aqueous system is mainly caused by redox reactions. [4] Chemiluminescence after a reaction of hydrogen peroxide and luminol. Luminol in an alkaline solution with hydrogen peroxide in the presence of iron or copper, [5] or an auxiliary oxidant, [6] produces 3-aminophtalate in an excited state, which exhibits ...
Reagents are "substances or compounds that are added to a system in order to bring about a chemical reaction or are added to see if a reaction occurs." [1] Some reagents are just a single element. However, most processes require reagents made of chemical compounds. Some of the most common ones used widely for specific reactive functions are ...
It is sometimes referred to as Baeyer's reagent after the German organic chemist Adolf von Baeyer. The reagent is an alkaline solution of potassium permanganate. Reaction with double or triple bonds (R 2 C=CR 2 or R−C≡C−R) causes the color to fade from purplish-pink to brown. Aldehydes and formic acid (and formates) also give a positive ...
Electrochemiluminescence or electrogenerated chemiluminescence (ECL) is a kind of luminescence produced during electrochemical reactions in solutions. In electrogenerated chemiluminescence, electrochemically generated intermediates undergo a highly exergonic reaction to produce an electronically excited state that then emits light upon relaxation to a lower-level state.
The sensitivity of the reagent may become altered after the recommended time period. [11] Microtox Osmotic Adjustment Solution (MOAS) is a nontoxic solution that is made up of 22% sodium chloride and ultra-pure water. This solution is added to a sample to adjust the osmotic pressure to approximately 2% NaCl. [11]
Guaiacol is usually derived from guaiacum or wood creosote. It is produced by a variety of plants. [4] It is also found in essential oils from celery seeds, tobacco leaves, orange leaves, and lemon peels. [5] The pure substance is colorless, but samples become yellow upon exposure to air and light.
Schultze reagent (also known as Chlor-Zinc-Iodine Solution) [1] is an oxidizing mixture consisting of a saturated aqueous solution of potassium chlorate KClO 3 and varying amounts of concentrated nitric acid HNO 3. It is commonly used in palynologic macerations. It was invented by Max Schultze.
Tebbe's reagent is the organometallic compound with the formula (C 5 H 5) 2 TiCH 2 ClAl(CH 3) 2. It is used in the methylidenation of carbonyl compounds, that is it converts organic compounds containing the R 2 C=O group into the related R 2 C=CH 2 derivative. [ 1 ]
