Hydrochloric acid is a strong inorganic acid that is used in many industrial processes such as refining metal. The application often determines the required product quality. [25] Hydrogen chloride, not hydrochloric acid, is used more widely in industrial organic chemistry, e.g. for vinyl chloride and dichloroethane. [8]
In the International System of Units (SI), the coherent unit for molar concentration is mol/m 3. However, most chemical literature traditionally uses mol/dm 3, which is the same as mol/L. This traditional unit is often called a molar and denoted by the letter M, for example: 1 mol/m 3 = 10 −3 mol/dm 3 = 10 −3 mol/L = 10 −3 M = 1 mM = 1 ...
Hydrochloric acid, a solution of hydrogen chloride in water; Hydrochloride, the salt of hydrochloric acid and an organic base; Hydrogen chloride, chemical formula HCl; Hypomania Checklist, a questionnaire used to screen for hypomania and bipolar spectrum disorders; HCL color space, a color space model designed to accord with human perception of ...
Perchloric acid is a mineral acid with the formula H Cl O 4. It is an oxoacid of chlorine . Usually found as an aqueous solution, this colorless compound is a stronger acid than sulfuric acid , nitric acid and hydrochloric acid .
The heat of dilution can be defined from two perspectives: the differential heat and the integral heat. The differential heat of dilution is viewed on a micro scale, which is associated with the process in which a small amount of solvent is added to a large quantity of solution. The molar differential heat of dilution is thus defined as the enthalpy
Normality can be used for acid-base titrations. For example, sulfuric acid (H 2 SO 4) is a diprotic acid. Since only 0.5 mol of H 2 SO 4 are needed to neutralize 1 mol of OH −, the equivalence factor is: f eq (H 2 SO 4) = 0.5. If the concentration of a sulfuric acid solution is c(H 2 SO 4) = 1 mol/L, then its normality is 2 N. It can also be ...
Conversely, the addition of acid converts weak acid anions to CO 2 and continuous addition of strong acids can cause the alkalinity to become less than zero. [12] For example, the following reactions take place during the addition of acid to a typical seawater solution: B(OH) − 4 + H + → B(OH) 3 + H 2 O OH − + H + → H 2 O PO 3− 4 + 2 ...
An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids , whose acidity is associated with their carboxyl group –COOH. Sulfonic acids , containing the group –SO 2 OH, are relatively stronger acids.
