Chloranil is a quinone with the molecular formula C 6 Cl 4 O 2. Also known as tetrachloro-1,4-benzoquinone, it is a yellow solid. Also known as tetrachloro-1,4-benzoquinone, it is a yellow solid. Like the parent benzoquinone, chloranil is a planar molecule [ 2 ] that functions as a mild oxidant.
Mass fraction can also be expressed, with a denominator of 100, as percentage by mass (in commercial contexts often called percentage by weight, abbreviated wt.% or % w/w; see mass versus weight). It is one way of expressing the composition of a mixture in a dimensionless size ; mole fraction (percentage by moles , mol%) and volume fraction ...
It is a red-orange solid. The compound is obtained by hydrolysis of chloranil: C 6 Cl 4 O 2 + 2 H 2 O → C 6 Cl 2 O 2 (OH) 2 + 2 HCl. It is centrosymmetric, planar molecule. It also crystallizes as a dihydrate. [2] Chloranilic acid is a noteworthy hydroxyquinone that is somewhat acidic owing to the presence of the two chloride substituents.
In chemistry, the lever rule is a formula used to determine the mole fraction (x i) or the mass fraction (w i) of each phase of a binary equilibrium phase diagram.It can be used to determine the fraction of liquid and solid phases for a given binary composition and temperature that is between the liquidus and solidus line.
It is the same concept as volume percent (vol%) except that the latter is expressed with a denominator of 100, e.g., 18%. The volume fraction coincides with the volume concentration in ideal solutions where the volumes of the constituents are additive (the volume of the solution is equal to the sum of the volumes of its ingredients).
Antoine Lavoisier is regarded as the inventor of elemental analysis as a quantitative, experimental tool to assess the chemical composition of a compound. At the time, elemental analysis was based on the gravimetric determination of specific absorbent materials before and after selective adsorption of the combustion gases.
The strength of commercial chlorine-releasing products may be instead specified as the concentration of the active ingredient, as mass or weight percent or grams per liter. In order to determine the free chlorine content of the product, one must take into account the oxidizing reactions that the ingredient may undergo in the application.
Dettol antiseptic liquid is a product produced by the Dettol Brand for Reckitt. It is light yellow in color in the concentrated form but, as several of the ingredients are insoluble in water, it produces a milky emulsion of oil droplets when diluted with water, exhibiting the ouzo effect .
