NH 4 Cl + NaOH → NH 3 + NaCl + H 2 O. Similarly, ammonium chloride also reacts with alkali-metal carbonates at elevated temperatures, giving ammonia and alkali-metal chloride: 2 NH 4 Cl + Na 2 CO 3 → 2 NaCl + CO 2 + H 2 O + 2 NH 3. A solution of 5% by mass of ammonium chloride in water has a pH in the range 4.6 to 6.0. [12]

Cl 2 (g) + 2 NaOH(aq) → NaCl(aq) + NaClO(aq) + H 2 O. Hence, chlorine is simultaneously reduced and oxidized; this process is known as disproportionation. [citation needed] The process is also used to prepare the pentahydrate NaOCl·5H 2 O for industrial and laboratory use. In a typical process, chlorine gas is added to a 45–48% NaOH solution.
Chloramines refer to derivatives of ammonia and organic amines wherein one or more N−H bonds have been replaced by N−Cl bonds. [1] [2] Two classes of compounds are considered: inorganic chloramines and organic chloramines.
In chemistry, an acid dissociation constant (also known as acidity constant, or acid-ionization constant; denoted ) is a quantitative measure of the strength of an acid in solution.
In thermochemistry, the enthalpy of solution (heat of solution or enthalpy of solvation) is the enthalpy change associated with the dissolution of a substance in a solvent at constant pressure resulting in infinite dilution.
Structure of ammonium chloride. Acid–base property of the resulting solution from a neutralization reaction depends on the remaining salt products. A salt containing reactive cations undergo hydrolysis by which they react with water molecules, causing deprotonation of the conjugate acids.
In organic chemistry, a cyanohydrin reaction is an organic reaction in which an aldehyde (−CH=O) or ketone (>C=O) reacts with a cyanide anion (N≡C −) or a nitrile (−C≡N) to form a cyanohydrin (>C(OH)C≡N).
