Answer:
Acid Definition Chemistry
The term acid and base have been defined in different ways, depending on the particular way of looking at the properties of acidity and basicity. Arrhenius first defined acids as compounds which ionize to produce hydrogen ions, and bases as compounds which ionize to produce hydroxide ions. According to the Lowry-Bronsted definition, an acid is a proton donor and a base is a proton acceptor.
According to the Lewis definition, acids are molecules or ions capable of coordinating with unshared electron pairs, and bases are molecules or ions having unshared electron pairs available for sharing with acids. To be acidic in the Lewis sense, a molecule must be electron deficient. This is the most general acid base concept. All Lowery Bronstead acids are Lewis acids but, in addition, the Lewis definition includes many other reagents such as boron trifluoride, aluminium chloride, etc.
Explanation:
Alkali is a base.
It is a base that dissolves in water.
This is very important to remember-
Not all bases are alkali but all alkali is base.
It is a basic salt alkali earth metal or alkali metal.
On adding alkali to acid the pH of the mixture increase.
On adding acid to alkali the pH decreases due to the removal of alkali.
Neutralization is a reaction in which removal of alkalinity or acidity occurs
