Question

what are amphoteric oxides give reactions with acid and bases

Answer 1

hi meet here is your answer
In chemistry, an amphoteric compound is a molecule or ion that can react both as anacid and as a base. ... Metal oxides whichreact with both acids as well as bases to produce salts and water are known asamphoteric oxides. Amphoteric oxidesinclude lead oxide and zinc oxide, among many others.
hope it's helpful for you, :-)

Answer 2

$\huge {ANSWER}$

${AMPHOTERIC \: OXIDE }$

▶The compounds which when react with acid or alkali will give salt and water as end produce.

⚫${Amphoteric oxide /hydroxide +acid \longrightarrow salt + water}$

⚫${Amphoteric oxide /hydroxide +alkali \longrightarrow salt + water}$

▶EXAMPLE :--

⚛$Zinc, Aluminium \: and \: lead \:forms \: amphoteric \: compounds$

⚛Compounds like (Zinc oxide) ZnO, (Lead II oxide) PbO, (bauxite )Al_2O_3 ,(Zinc hydroxide) Zn(OH),(Lead hydroxide)Pb(OH)_2 and (aluminum hydroxide) Al(OH)_3.

▶EQUATION :--

✳$ZnO + 2NaOH \longrightarrow Na_2ZnO_2 +H_2O$

✳$Zn(OH)_2+2NaOH \longrightarrow Na_2ZnO_2 +2H_2O$

✳$PbO + 2NaOH \longrightarrow Na_2PbO_2 +H_2O$

✳$Pb(OH)_2+ 2NaOH \longrightarrow Na_2PbO_2 +2H_2O$

✳$Al_2O_3+ 2NaOH \longrightarrow 2NaAlO_2 +H_2O$

✳$Al(OH)_3+ NaOH \longrightarrow NaAlO_2+2H_2O$
