The chemical equation for the reaction of potassium with water is 2K(s) + 2H2O(l) → 2KOH(aq) + H2(g).
Chemical Equation
- Chemical reactions are modeled using chemical equations.
- Reactants are on one side of the arrow in this equation, and products are on the other.
Chemical equations utilize symbols to indicate things like the direction of a reaction and the physical states of the parties involved in the process. The first chemical equation was developed in 1615 by the French chemist Jean Beguin.
Representing the Physical States of the Reacting Entities:
The responsive and producing entities' stoichiometric coefficients are written adjacent to symbols in parenthesis that indicate their physical states as the chemical reaction advances. Any of the following could be depicted in these images.
● An entity in the solid state is denoted by the symbol (s).
● The liquid condition of an entity is indicated by the symbol (l).
● The entity is implied to be in the gaseous state by the symbol (g).
● An aqueous solution of an entity is indicated by the symbol (aq) that corresponds to it in a chemical equation.
A reactant or product in some reactions could take the form of a precipitate that is insoluble in the solution in which the reaction is occurring. These substances are designated as precipitates by the symbol "↓" next to their chemical formulas.
The reaction of potassium with water:
● Potassium reacts vehemently with water to produce potassium hydroxide as well as hydrogen gas.
● The following chemical formula describes how potassium reacts with water:
2K(s)+2H2O(l)→2KOH(aq)+H2(g)
