Hoàn thành chuỗi phản ứng sau: ​ (1) K2MnO4 --->Cl2 ---->KCl---->KOH---->KClO3 ​(2) KMnO4----> Cl2----> HCl ---->KCl --->KNO3

(1): $K_{2} MnO_{4} +8HCl\rightarrow 2KCl+MnCl_{2} +2Cl_{2} +4H_{2} O$

$2K+Cl_{2}\rightarrow 2KCl$

$2KCl+H_{2} O\xrightarrow{đpdd\ có\ màng\ ngăn} 2KOH+Cl_{2} +H_{2}$

$6KOH+3Cl_{2}\rightarrow 5KCl+KClO_{3} +3H_{2} O$

(2): $2KMnO_{4} +16HCl\rightarrow 2KCl+2MnCl_{2} +5Cl_{2} +8H_{2} O$

$Cl_{2} +H_{2}\xrightarrow{as} 2HCl$

$2K+2HCl\rightarrow 2KCl+H_{2}$

$KCl+AgNO_{3}\rightarrow AgCl+KNO_{3}$
