ALKALINE REACTION Meaning and
Definition
-
Alkaline reaction refers to the characteristic property of a substance or solution to exhibit basic or alkaline properties when it comes into contact with water or undergoes a chemical reaction. It is a term commonly used in chemistry to describe the behavior of substances that have a pH level higher than 7 on the pH scale.
When a substance shows an alkaline reaction, it means it has the ability to neutralize acids, forming water and a salt. It typically indicates the presence of hydroxide ions (OH-) in solution. Alkaline substances have a sour taste and can feel slippery or soapy to touch. They can also turn litmus paper from red to blue, as litmus paper is commonly used to test pH levels.
In nature, alkaline reactions can occur in various ways. For example, when certain metals, such as sodium or potassium, react with water, they form hydroxide ions, resulting in an alkaline solution. Likewise, some minerals and compounds found in the earth or water sources can also exhibit alkaline properties. The phenomenon of alkaline reactions is crucial in various chemical processes, industrial applications, and biological systems, as it dictates the behavior and reactivity of substances in these contexts.
Overall, the alkaline reaction is a fundamental concept in chemistry that describes the ability of a substance or solution to display basic properties, opposing the acidic nature while contributing to the pH scale.

Etymology of ALKALINE REACTION
The word "alkaline" originated from the Arabic word "al-qalī" which means "the ashes". The term was initially used to describe the substance obtained by burning certain plants to create a basic or alkaline substance. The term "alkali" was then adopted into Latin as "alkali" and subsequently evolved into "alkaline" in English.
The term "reaction" in this context refers to the chemical reaction that occurs when an alkaline substance comes into contact with an acid, resulting in the formation of water and a salt. This term originated from the Latin word "reactio", which means a "change" or "response".
