Ammonium chloride can acidify the soil over time, so soil pH is regularly monitored, especially when growing plants sensitive to acidic conditions. [19] Some plants are sensitive to chloride ions (e.g., avocados, beans, grapes), so applying ammonium chloride to such plants should be done with extra caution to prevent chloride toxicity. [20]
If it is the result of a reaction between a strong acid and a strong base, the result is a neutral salt. Weak acids reacted with weak bases can produce ionic compounds with both the conjugate base ion and conjugate acid ion, such as ammonium acetate. Some ions are classed as amphoteric, being able to react with either an acid or a base. [59]
A simple example of a polyatomic ion is the hydroxide ion, which consists of one oxygen atom and one hydrogen atom, jointly carrying a net charge of −1; its chemical formula is O H −. In contrast, an ammonium ion consists of one nitrogen atom and four hydrogen atoms, with a charge of +1; its chemical formula is N H + 4.
Although most compounds are referred to by their IUPAC systematic names ... Ammonium chloride – [NH 4]Cl [39] ... Oxygen difluoride – OF 2;
This often causes ionic compounds to be very stable. Ionic bonds have high bond energy. Bond energy is the mean amount of energy required to break the bond in the gaseous state. Most ionic compounds exist in the form of a crystal structure, in which the ions occupy the corners of the crystal.
In chemistry, an oxonium ion is any cation containing an oxygen atom that has three bonds and 1+ formal charge. [1] The simplest oxonium ion is the hydronium ion ( H 3 O + ). [ 2 ]
Oxygen fluoride(s), bromine oxide(s), iodine oxide(s) – analogous oxygen halide and halogen oxides; Sulfur fluoride(s), sulfur chloride(s), sulfur bromide(s), sulfur iodide(s) – analogous sulfur halides, some of which are valence isoelectronic with chlorine oxides.
If the pH is high (the concentration of hydrogen ions is low and hydroxide ions is high), the equilibrium shifts to the left: the hydroxide ion abstracts a proton from the ammonium ion, generating ammonia. Formation of ammonium compounds can also occur in the vapor phase; for example, when ammonia vapor comes in contact with hydrogen chloride ...
