An Alkali is a soluble base.
A Base may be a ssolid , that will dissolve in water, whereupon it becomes an alkali.
Sodium oxide is a solid base (Na2O) . However, when it is dissolved in water it becomes the alkali sodium hydroxide. (NaOH)
Na2O + H2O = 2NaOH .

Bases are substances that can accept protons, while alkaline refers specifically to a solution with a pH greater than 7 due to the presence of bases. In other words, all alkaline solutions contain bases, but not all bases lead to alkaline solutions.
A base is an alkali substance but only when disolved in water, eg/ Copper Sulphate[aq]
Base substances and alkaline substances are often used interchangeably, but there is a subtle difference between the two. Bases are substances that can accept protons, while alkaline substances specifically refer to bases that have a pH greater than 7. In other words, all alkaline substances are bases, but not all bases are necessarily alkaline.
There is no difference between an alkaline battery and a pile alkaline battery. "Pile" is just a term used in French to refer to a battery. Both terms describe the same type of battery that uses an alkaline electrolyte.
No, salt is not alkaline. Salt is a neutral compound that is formed from the reaction between an acid and a base.
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.
Yes, a base is alkaline because it has a pH above 7. Bases accept protons (H+) in reactions, unlike acids which donate protons.
