Detailed Solution

I) The aqueous solutin of boric acid is used as antiseptic in the name of boric lotion.→ Boric acid is also used as food preservative.II) In diborane each boron undergoes sp3 hybridisation.In diborane each B atom undergoes sp3  hybridisation, it contains two B-H-B bridges. Each bridge bond is formed by overlapping of one "B"sp3  hybrid orbital with one electron, hydrogen s-orbital with one electron and another boron sp3 hybrid orbital without electron. That is the bridge head bond is a electron deficient three centre two electron bond.                                                                                                                                   II) The aqueous solution of borax is alkaline in nature.Scince in aqueous borax undergoes anionic hydrolysis.The cation of strong base (Na+)  cannot undergo hydrolysis,where as anion of weak acid( B4O7-2) donot undergo hydrolysis.2Na+ + 2OH¯2NaOH
