Fluorine

Vedclass · Answer

(A, C, D) $SiO_{2}$ is an acidic oxide and reacts with both strong bases and specific fluorinating agents. $1$. $SiO_{2(s)} + 2F_{2(g)} \rightarrow SiF_{4(g)} + O_{2(g)}$ $2$. $SiO_{2(s)} + 6HF(aq.) \rightarrow H_{2}SiF_{6}(aq.) + 2H_{2}O(\ell)$ $3$. $SiO_{2(s)} + 2NaOH(aq.) \rightarrow Na_{2}SiO_{3}(aq.) + H_{2}O(\ell)$ Since $HF$,hot $NaOH$,and $F_{2}$ all react with $SiO_{2}$,the question implies identifying reagents that attack it. Given the standard multiple-choice format,this is a multiple-correct type question.

$SiO_{2}$ is attacked by which of the following?
