Question

Cl2+NaOH－NaCl+NaClO3+H2O条件为加热

怎么配平它，求详细步骤

Answer 1

3 Cl2+6 NaOH = 5 NaCl+NaClO3+3 H2O

Cl： 0 → -1； Cl：0 → +5
所以 NaCl配5，NaClO3配1，Cl2配3：3 Cl2+NaOH —— 5 NaCl+NaClO3+H2O
然后配平 NaOH、H2O：3 Cl2+6 NaOH = 5 NaCl+NaClO3+3 H2O

Answer 2

可以这样“理解”
Cl2+H2O=HCl+HClO
HCl+NaOH=NaCl+H2O
HClO+NaOH=NaClO+H2O

总反应方程式为
Cl2 + 2NaOH = NaCl + NaClO + H2O
加热的同理
可以先3Cl2+3H2O=5HCl+HClO3
5HCl+5NaOH=5NaCl+5H2O
HClO3+NaOH=NaClO3+H2O
总反应方程式为
3Cl2 + 6NaOH = 5NaCl + NaClO3 + 3H2O

3Cl2+3H2O=5HCl+HClO3 Cl降一升五，HCl前5，总6配平即可

Answer 3

3CL2+6NAOH加热=5NACL+NACLO3++3H2O

Answer 4

3Cl2+6NaOH=5NaCl+NaClO3+3H2O，H较少，先配H
