Double Displacement or Replacement Reaction- Also called a metathesis reaction, this occurs when both cations and anions of the reactants trade places to form products. While some reactions involve a change in the state of matter (e.g., liquid to gas phase), a phase change is not necessaril...
Redox reactions involve electron transfers; if one species gains electrons, another species (or more than one species) must lose electrons. For example, the redox reaction in which zinc displaces copper in an aqueous solution of copper sulfate:...
In the traditional acid/base neutralization reaction of H+and OH-, H+is a Lewis acid because it accepts an electron pair from the OH-. Lewis Acid Example 2 Boron trifluoride acts as a Lewis acid when it accepts an electron pair from ammonia to form a co-ordinate covalent bond - i.e....
I have a rather quick question on the definition of Nucleophilicity. To get straight to the point, am I right in saying that the most appropriate definition of Nucleophilicity, regardless of whether the reaction takes place in solvent or in the gas phase, is the following; Nucleophilicity is ...

2.Potassium hydroxide dissolved in waterproduces a highly conductive electrolyte in the Edison cell, an early rechargeable cell. Crude schematic of Edison cell discharging. Unlike in the case of sodium production above, no electrolyte is consumed in this reaction. The potassium hydroxide's role in ...
Strictly defined, ionization is the complete loss of an electron from an atomic or molecular species. The resulting species is called an ion. In chemical equations, the charge on ions is shown as a superscript, such as in this simple ionization reaction: ...
