thank you for the answers
An alkaline solution is one where the pH is greater than 7. Alkaline solutions are also known as basic solutions. They can be generated when metal oxides or metal hydroxides are put into water to dissolve. Examples of an alkaline solutions are sodium hydroxide solutions or potassium hydroxide solutions.
Yes
Bases which are soluble in water

The substance in which water is added
An Alkaline can be defined as a base that dissolves in water.
The bases which are soluble in water are called alkaline. For example, sodium hydroxide (NaOH), potassium hydroxide (KOH)…HOPE IT HELPS???
Have u written the correct spelling
Plz give me abswer

Basic solution dissolved in water or in aqueous form example sodium hydroxide, calcium hydroxide etc

When an alkali is dissolved in water, the solution formed is known as alkaline solution. They can be formed in the laboratory or via natural processes also like erosion. Alkaline solution is basic in nature so used in the laboratory, industry etc. to make chemical reactions basic or neutral.
having the properties of an alkali or alkali metal : basic especially, of a solution : having a pH of more than 7

Solution in which base is soluble in water. It has pH value more than 7.
a chemical substance that reacts with acid to form a salt has a pH value of more than 7.
The base soluble in water is known as alkaline.
Scientists use pH to describe how acidic a substance is on a scale of 0 to 14. By definition, a substance is alkaline if it has a pH of over 7.
The base which can be dissolved in water is alkaline

Those bases completely dissolve in water is called alkaline.
Water soluble base are called alkaline.
The bases which dissolved in water known as alkaline
