JudyBases are substances that can accept protons according to the Brønsted-Lowry definition, while alkalis are bases that are soluble in water. Essentially, all alkalis are bases, but not all bases are alkalis. Alkalis typically release hydroxide ions in solution, while bases may or may not release hydroxide ions depending on their solubility in water.

Is alkali another name for a base?
Yes, alkali is often used interchangeably with base in chemistry. Bases are substances that can accept protons (H+) and increase the pH of a solution. Alkalis are a subset of bases that dissolve in water and typically come from the alkali metals on the periodic table.
Difference between a base and alkali?
A base in chemistry is a substance that can accept hydrogen ions(acids) or more generally, donate electron pairs. A soluble base is referred to as an alkali if it contains and releases hydroxide ions (OH−) quantitatively.Soluble- (of a substance) capable of being dissolved.
What is the difference between alkali and alkaline substances?
Alkali substances are bases that dissolve in water, while alkaline substances are compounds that have a pH greater than 7.
What is the difference between alkaline and alkali substances?
Alkaline substances have a pH greater than 7, while alkali substances are specifically bases that can dissolve in water.
What is difference between alkali and base?
Statement: "All alkali are bases but not all bases are alkali"Alkali is a basic, ionic salt of an alkali metal or alkaline earth metal element. Alkalis are best known for being bases that dissolve in water. (Most common form is hydroxide.) This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of a base and are still among the more common bases.Since Brønsted-Lowry acid-base theory, the term alkali in chemistry is normally restricted to those salts containing alkali and alkaline earth metal elements.A base is most commonly thought of as an aqueous substance that can accept H+ ions.A soluble base is also often referred to as an alkali if hydroxide ions (OH−) are involved.This refers to the Brønsted-Lowry theory of acids and bases.Alternative definitions of bases include electron pair donors (Lewis), and as sources of hydroxide anions (Arrhenius).Examples of simple bases are sodium hydroxide (NaOH, which is thus an alkali and base) and ammonia (NH3 which is not 'alkali' but base).
