Answer 2

$\huge\mathfrak\red{Answer}$

Alkaline refers to an aqueous solution having a pH greater than 7 or a [OH-] greater than 10-7. An alkaline solution is also known as basic.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.

Examples:-

Those metals that belong to group II of the periodic table and make hydroxides like beryllium, magnesium, calcium, strontium, barium and radium are known as alkaline earth metals.

Additional information:-

Some examples of alkaline solutions include sodium hydroxide, potassium hydroxide, magnesium hydroxide and calcium carbonate. Each of these solutions has different applications in different industries. Manufacturers commonly use alkaline solutions in products such as bio-diesel fuels, soaps, medications, detergents and cleaning products. Additionally, manufacturers use alkaline solutions in many food preparations and specialized applications. As cleaning agents alkaline solutions can dissolve fats, grease, oils and protein.
