The Leuckart reaction is the chemical reaction that converts aldehydes or ketones to amines by reductive amination in the presence of heat. [1] [2] The reaction, named after Rudolf Leuckart, uses either ammonium formate or formamide as the nitrogen donor and reducing agent. [3]
For example, carbon monoxide is a very weak Brønsted–Lowry base but it forms a strong adduct with BF 3. In another comparison of Lewis and Brønsted–Lowry acidity by Brown and Kanner, [19] 2,6-di-t-butylpyridine reacts to form the hydrochloride salt with HCl but does not react with BF 3.
Peracetic acid (also known as peroxyacetic acid, or PAA) is an organic compound with the formula CH 3 CO 3 H. This peroxy acid is a colorless liquid with a characteristic acrid odor reminiscent of acetic acid.
Phenolphthalein adopts different forms in aqueous solution depending on the pH of the solution. [4] [2] [5] [6] Inconsistency exists in the literature about hydrated forms of the compounds and the color of sulfuric acid. Wittke reported in 1983 that it exists in protonated form (H 3 In +) under strongly acidic conditions, providing an orange ...
The anionic (HO 2 C(CH 2) 4 CO 2 −) and dianionic (− O 2 C(CH 2) 4 CO 2 −) forms of adipic acid are referred to as adipates. An adipate compound is a carboxylate salt or ester of the acid. Some adipate salts are used as acidity regulators, including: Sodium adipate (E number E356) Potassium adipate (E357) Some adipate esters are used as ...
Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH).Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average.
The Philippine General Hospital (also known as University of the Philippines–Philippine General Hospital or UP–Philippine General Hospital), simply referred to as UP–PGH or PGH, is a tertiary state-owned hospital administered and operated by the University of the Philippines Manila.
A strong acid will react with a weak base to form an acidic (pH < 7) solution. A weak acid will react with a strong base to form a basic (pH > 7) solution. These indicators are essential tools in chemistry and biology, aiding in the determination of a solution's acidity or alkalinity through the observation of colour transitions. [ 10 ]
