  • In chemistry, 'alkaline' specifically refers to substances that release hydroxide ions (OH-) when dissolved in water.

The term alkaline originates from the Arabic word 'al-qili', which refers to the ashes of certain plants that have a basic (as opposed to acidic) quality. This word was adopted into Latin as 'alcalis', which indicated the ash of certain plants that create a strong base when dissolved in water. By the late 19th century, the term 'alkaline' began to be used in English to describe any substance that had properties of an alkali, especially those having a pH above 7. Over time, the usage of the term expanded to cover a broader range of substances in chemistry, agriculture, and related fields, indicating its significance in various scientific disciplines.
