"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).
Alkali are acidic solutions, these are liquids with a pH less than 7 and a base is a solution with a pH higher than 7, one of the few exceptions are water that has a pH of exactly 7 when it is pure
Even I this n my assignment cannot find the answer pls help me
An alkali is a base that is soluble in water. Most of the common hydroxides are alkali.
For example:- NaOH, KOH are common alkali's.
Alkali is OH- so it is base.
Both of them have PH value more than 7
A base is an alkali substance but only when disolved in water, eg/ Copper Sulphate[aq]
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.
The difference is not very big, even quite formally, I'd say.Alkali are hydroxidesBase is a substance capable of reaction with protons (H+ ions) donated by acids.So:All alkali's in solution are bases,but not all bases are alkali: for example NH3 basic but not a hydroxide of a metal ion.
Nothing, both are terms for the free base (as in acid/base in chemistry) form of the cocaine alkaloid. This is obtained by mixing ordinary cocaine hydrochloride salt with an alkali.
an acid has a pH under 7 an alkali has a pH over 7

an alkali is much stronger than an acid because an acid has a PH of 1 and an alkali has a PH of 14.
yes
Alkaoids are in the biology and alkalis are in. The chemesyry
The difference between basic and alkaline is;- An ALKALI is a soluble Base. or A BASE tat dissolves in water . Metal oxides are bases. If they are soluble , they will dissolve in water and become alkalis.
There is no clear difference between base and soap because soap is a base.
