It hydrolysed to form sodium borate, NaB(OH)4[tex]NaB(OH)_4[/tex] and boric acid.
Explanation
Borax is an important mineral, boron compound and is a salt of 'boric acid'. The powdered borax consists of soft colourless crystals that will dissolve in water. It is used in many detergents, enamel glazes and cosmetics.
When mixed with water it produces to form an ion known as the borate ion. Thus hydrolysed to form sodium borate,[tex]NaB(OH)_4[/tex] and boric acid that is chemically written as B(OH)3 or [tex]H_3BO_3.[/tex]
Answer:
The dissolution of borax in water will results in boric acid and hydroxide ions.
Explanation:
Borax is chemically known as sodium tetraborate decahydrate with molecular formula [tex]\rm Na_2B_4O_7.10H_2O[/tex]. Borax is a white crystal compound with polar solubility. It is considered as an active ingredient in soaps, detergents and cleaning. The dissolution of borax in water will result in the formation of a boric acid and hydroxide ions.
The dissolution reaction of Borax in water is as follows:
[tex]\rm Na_2BrO_7.10H_2O\;\rightarrow\;Na^2^+\;+\;B_4O_5\left (OH \right )_4^2^-\;+\;H_2O[/tex]
[tex]\rm B_4_0_5\left ( OH\right )_4^2^-\;+\;H_2O\;\rightarrow\;H_3BO_3\;+\;OH^-[/tex]
The boric acid formed is a weak acid, while the hydroxide is a strong base.
