A) \[{{\operatorname{SnO}}_{2}}\]
B) CaO
C) \[Si{{O}_{2}}\]
D) \[C{{O}_{2}}\]
Correct Answer: A
Solution :
\[Sn{{O}_{2}}\] is an amphoteric oxide because it reacts with acids as well as with bases to form corresponding salts. \[Sn{{O}_{2}}+2{{H}_{2}}S{{O}_{4}}(conc)\xrightarrow{{}}Sn{{(S{{O}_{4}})}_{2}}+2{{H}_{2}}O\]\[Sn{{O}_{2}}+2NaOH\,\xrightarrow{{}}\,N{{a}_{2}}Sn{{O}_{3}}\,\,+\,\,{{H}_{2}}O\]
