Bromine water is an oxidizing, intense brown mixture containing diatomic bromine (Br 2) dissolved in water (H 2 O). [1] It is often used as a reactive in chemical assays of recognition for substances which react with bromine in an aqueous environment with the halogenation mechanism, mainly unsaturated carbon compounds (carbon compounds with 1 ...
Condensation reaction. In organic chemistry, a condensation reaction is a type of chemical reaction in which two molecules are combined to form a single molecule, usually with the loss of a small molecule such as water. [1] If water is lost, the reaction is also known as a dehydration synthesis. However other molecules can also be lost, such as ...
Agents such as hydrogen peroxide, elemental chlorine, hypochlorous acid (chlorine water), bromine, bromine water, iodine, nitric and oxidising acids, and ozone react with sensitive moieties such as sulfide/thiol, activated aromatic rings (phenylalanine) in effect damage the protein and render it useless.
Hammett equation. In organic chemistry, the Hammett equation describes a linear free-energy relationship relating reaction rates and equilibrium constants for many reactions involving benzoic acid derivatives with meta- and para- substituents to each other with just two parameters: a substituent constant and a reaction constant. [1][2] This ...
The hydrogen ion, or hydronium ion, is a Brønsted–Lowry acid when dissolved in H 2 O and the hydroxide ion is a base because of the autoionization of water reaction An analogous reaction occurs in liquid ammonia
Vinegar is at least 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. It has been used, as a component of vinegar, throughout history from at least the third century BC. Acetic acid is also known as acetyl hydroxide (AcOH). Acetic acid is the second simplest carboxylic acid (after formic acid).
High levels of bromine can convert phenol red to bromophenol red (dibromophenolsulfonephthalein, whose lowered p Ka results in an indicator with a range shifted in the acidic direction – water at pH 6.8 will appear to test at 7.5).
Solvent effects. In chemistry, solvent effects are the influence of a solvent on chemical reactivity or molecular associations. Solvents can have an effect on solubility, stability and reaction rates and choosing the appropriate solvent allows for thermodynamic and kinetic control over a chemical reaction. A solute dissolves in a solvent when ...
