Base (chemistry)
Videos
In chemistry, there are three definitions in common use of the word "base": Arrhenius bases, Brønsted bases, and Lewis bases. All definitions agree that bases are substances that react with acids, as
Soaps are weak bases formed by the reaction of fatty acids with sodium hydroxide or potassium hydroxide.

A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. When chemical reactions occur, the atoms are rearranged and the reaction is acc
A thermite reaction using iron(III) oxide. The sparks flying outwards are globules of molten iron trailing smoke in their wake.
Antoine Lavoisier developed the theory of combustion as a chemical reaction with oxygen.
As seen from the equation CH4 + 2O2 → CO2 + 2 H2O, a coefficient of 2 must be placed before the oxygen gas on the reactants side and before the water on the products side so that, as per the law of conservation of mass, the quantity of each element does not change during the reaction.
Sodium chloride is formed through the redox reaction of sodium metal and chlorine gas
