|
Barium chloride is the most frequently used laboratory source of barium ions for syntheses and analyses. Danger! Poison! May be fatal if swallowed. Causes irritation. May be harmful if inhaled.
|
Barium hydroxide is used in analytical chemistry for the titration of weak acids. Its clear aqueous solution is guaranteed to be free of carbonate, unlike those of sodium hydroxide and potassium hydroxide, as barium carbonate is insoluble in water
|
Benzene is an organic chemical compound. It is composed of 6 carbon atoms in a ring, with 1 hydrogen atom attached to each carbon atom, with the molecular formula C6H6.
|
Benzoic acid, C7H6O2 (or C6H5COOH), is a colorless crystalline solid and the simplest aromatic carboxylic acid. The name derived from gum benzoin, which was for a long time the only source for benzoic acid.
|
Bismuth is a chemical element that has atomic number 83 and has been given the chemical symbol Bi
|
Biuret reagent is a test reagent for the presence of proteins. The blue reagent solution turns violet if a protein is present, shifting to pink if a short-chain polypeptide is present.
|
Boric acid, also called boracic acid or orthoboric acid or acidum boricum, is a weak acid of boron often used as an antiseptic, insecticide, flame retardant, as a neutron absorber, and as a precursor of other chemical compounds.
|
Cadmium bromide is a cream-coloured crystalline ionic cadmium salt of hydrobromic acid that is soluble in water. It is very toxic, along with other cadmium compounds. Cadmium bromide is used in "Wet Plate Collodion Photography".
|
Caffeine is a bitter, white crystalline xanthine alkaloid that is a psychoactive stimulant.
