Hoàn thành chuỗi phản ứng: Cl2->KClO3->KCl->HCl->CuCl2->AgCl->Cl2->Clorua vôi
2 câu trả lời
$3Cl_2$ $+6KOH$ $\xrightarrow{100^0C}$ $5KCl$ $+KClO_3$ $+3H_2O$
$2KClO_3$ $\xrightarrow{t^0}$ $2KCl$ $+$ $3O_2$
$2KCl$ $+$ $H_2SO_4$ $\xrightarrow{}$ $K_2SO_4$ $+$ $2HCl↑$
$2HCl$ $+$ $CuO$ $→$ $CuCl_2$ $+$ $H_2O$
$CuCl_2$ $+$ $AgNO_3$ $→$ $AgCl↓$ $+$ $Cu(NO3)_2$
$Cl_2$ $+$ $Ca(OH)_2$ $→$ $CaOCl_2$ $+H_2O$
Các phản ứng xảy ra:
\(6KOH + 3C{l_2}\xrightarrow{{{t^o}}}5KCl + KCl{O_3} + 3{H_2}O\)
\(2KCl{O_3}\xrightarrow{{{t^o}}}2KCl + 3{{\text{O}}_2}\)
\(KC{l_{rắn}} + {H_2}S{O_4}\xrightarrow{{{t^o}}}KH{\text{S}}{O_4} + HCl\)
\(CuO + 2HCl\xrightarrow{{}}CuC{l_2} + {H_2}O\)
\(CuC{l_2} + 2{\text{A}}gN{O_3}\xrightarrow{{}}Cu{(N{O_3})_2} + 2{\text{A}}gCl\)
\(2{\text{A}}gCl\xrightarrow{{{t^o}}}2{\text{A}}g + C{l_2}\)
\(Ca{(OH)_2} + C{l_2}\xrightarrow{{}}CaOC{l_2} + {H_2}O\)
