(a) It is a strong tribasic acid -- Incorrect.
(b) It is prepared by acidifying an aqueous solution of borax - Correct.
(c) It has a layer structure in which planar BO₃ units are joined by hydrogen bonds. - Correct.
(d) It does not act as proton donor but acts as a Lewis acid by accepting a lone pair of electrons. - Correct.
Option A is the answer.
An aqueous solution of borax is basic
Borax is a salt of a which is formed after the the reaction strong base (NaOH) and a weak acid (H3BO3)
since a strong base is added over a weak acid the resultant salt will be a base
Option (c) is the correct answer.
Chemical formula of borax is . It is a salt of strong base which is NaOH and a weak acid, that is, .
Thus, we can see that borax is basic in nature because a strong base is added in a weak acid.
Hence, we can conclude that an aqueous solution of borax is basic.
5.diborane with Ammonia.
4.heat reactions formed by toxic acids.
3.answer source is Google.
2.because after burning or acidified it, it only forms toxic. which is not harmful atall.
A option is not about this is false.
an aqueous sol of borax is basic in nature .bcoz borax reacts with water to form orthoboric acid and sodium hydroxide.since sodium hydroxide is a stong base . the aqueous sol of borax is basic in nature
Aqueous solution is used
When borax is dissolved in water it ionizes and hydrolysis of borate ion gives OH (the hydroxyl ion) and boric acid. Since boric acid is a weak acid AND Na-OH is strong a alkali an aqueous solution of borax is alkaline in nature.
Both acid and base show their property in aqueous solutions.
Because of this aqueous solution of borax is basic in nature
