Question

(a) Classify following oxides as neutral, acidic, basic or amphoteric:

CO, B 2 O 3 , SiO 2 , CO 2 , Al 2 O 3 , PbO 2 , Tl 2 O 3

(b) Write suitable chemical equations to show their nature.

Answer 1

heyy ur answer.........

neutral oxide--co

acidic oxide--B2O3,SiO2,Co2

basic oxide--TIO3

NEUTRAL---al2o3 and pbo2..........

(1) CO = Neutral 

(2) B2O3 = Acidic 

Being acidic, it reacts with bases to form salts. It reacts with NaOH to form sodium metaborate. 

(3) SiO2 = Acidic 

Being acidic, it reacts with bases to form salts. It reacts with NaOH to form sodium silicate. 

(4) CO2 = Acidic 

Being acidic, it reacts with bases to form salts. It reacts with NaOH to form sodium carbonate. 

(5) Al2O3 = Amphoteric 

Amphoteric substances react with both acids and bases. Al2O3 reacts with both NaOH and H2SO4. 

(6) PbO2 = Amphoteric 

Amphoteric substances react with both acids and bases. PbO2 reacts with both NaOH and H2SO4. 

(7) Tl2O3 = Basic 

Being basic, it reacts with acids to form salts. It reacts with HCl to form thallium chloride. ............
