Ph of dichloroacetic acid
WebChloroacetic acid, industrially known as monochloroacetic acid ( MCA ), is the organochlorine compound with the formula ClCH 2 CO 2 H. This carboxylic acid is a useful building block in organic synthesis. It is a colorless solid. Related compounds are dichloroacetic acid and trichloroacetic acid . WebDec 30, 2024 · The PHGs of 0.2 parts per billion (ppb) for DCA, 0.1 ppb for TCA, and 0.03 ppb for DBA are based on carcinogenicity and are set at a level of risk of one additional cancer case per one million persons exposed over a lifetime. The PHGs of 53 ppb for MCA and 25 ppb for MBA are based on noncancer health effects.

Weak acids are acids that don't completely dissociate in solution. In other words, a weak acid is any acid that is not a strong acid. The strength of a weak acid depends on how much it dissociates: the more it dissociates, the stronger the acid.
WebA strong acid and a strong base, such as HCl ( aq) and NaOH ( aq) will react to form a neutral solution since the conjugate partners produced are of negligible strength: (7.4.1) HCl ( a q) + NaOH ( a q) ⇌ NaCl ( a q) + H 2 O ( l) A strong acid and a weak base yield a weakly acidic solution, not because of the strong acid involved, but because ... The chemistry of dichloroacetic acid is typical for halogenated organic acids. It is a member of the chloroacetic acids family. The dichloroacetate ion is produced when the acid is mixed with water. As an acid with a pKa of 1.35, pure dichloroacetic acid is classed as a strong organic acid; it is very corrosive and extremely destructive to tissues of the mucous membranes and upper respiratory tract via inhalation.
WebIt is prepared by the reaction of chlorine with acetic acid in the presence of a suitable catalyst such as red phosphorus. This reaction is Hell–Volhard–Zelinsky halogenation .
