\(n_{NaOH}=0,2\left(mol\right)\)
\(PTHH:NaOH+HClO\rightarrow NaClO+H_2O\)
_______0,2________0,2_________________(mol)
Gọi \(\left\{{}\begin{matrix}n_{NaClO}=a\left(mol\right)\\n_{CaOCl2}=b\left(mol\right)\end{matrix}\right.\)
\(\Rightarrow74,5a+127b=20,15\left(1\right)\)
PTHH :
\(CO_2+NaClO+H_2O\rightarrow NaHCO_3+HClO\)
a______a ___________________________a
\(2CaOCl_2+CO_2+H_2O\rightarrow CaCO_3+CaCl_2+2HClO\)
b _______ 0,5b___________________________ b (mol)
\(\Rightarrow n_{HClO}=a+b=0,2\left(2\right)\)
\(\left(1\right)+\left(2\right)\Rightarrow\left\{{}\begin{matrix}a=0,1\\b=0,1\end{matrix}\right.\)
\(\Rightarrow n_{CO2}=a+0,5b=0,1+\frac{0,1}{2}=0,15\left(mol\right)\)
\(\Rightarrow V_{CO2}=0,15.22,4=3,36\left(l\right)\)
