Pronunciation: [alkˈɑːli] (IPA) 
The word "Alcali" is often misspelled as "Alkali," with an "k" instead of a "c." This word refers to a type of substance that has a high pH and can neutralize acids. The correct spelling is with a "c" because it comes from the Arabic word "al-qali" which means "the ashes." The pronunciation of "Alcali" is /ælˈkæli/ with emphasis on the first syllable and with a short "a" sound in the second syllable.
Alcali refers to a term commonly used in chemistry to designate a class of chemical compounds that possess alkaline or basic properties. These compounds, also known as bases, are characterized by having a pH greater than 7 and the ability to neutralize acids when they come into contact with each other. Alcali compounds typically have a bitter taste and a slippery or soapy texture.
Alcali substances are predominantly made up of hydroxides or carbonates of alkali metals such as sodium, potassium, lithium, rubidium, or cesium. They are highly soluble in water and are commonly found in various everyday products. Sodium hydroxide, also known as caustic soda, is one of the most widely used alcali compounds and is utilized in soap and detergent production, textile manufacturing, and as a strong chemical base.
In addition to their various industrial applications, alcalis also play important roles in many biological systems. For instance, they aid in maintaining the pH balance of the human body and are essential for numerous physiological processes. Additionally, alcalis are commonly used in laboratories for various experiments, including titrations and pH adjustments.
Overall, alcali serves as a descriptor for a group of basic compounds that play crucial roles in both fundamental chemical reactions and practical applications across a wide range of industries.
The word "alcali" derives from the Arabic term "qali" (القلي), which means "ashes". This term was originally used to refer to certain plants whose ashes were used in early soap-making processes. Over time, the word evolved and expanded to encompass various alkaline substances. It was later borrowed into other languages, including Spanish and English.
