\(n_{HClO}=\frac{7,875}{52,5}=0,15\left(mol\right)\)
Gọi \(\left\{{}\begin{matrix}n_{NaClO}=a\left(mol\right)\\n_{NaOCl2}=b\left(mol\right)\end{matrix}\right.\)
\(CO_2+NaClO+H_2O\rightarrow NaHCO_3+HClO\)
a_______ a_________________________a___ (mol)
\(CO_2+2CaOCl_2+H_2O\rightarrow CaCl_2+CaCO_3+2HClO\)
0,5b____b _________________________________b ___ (mol)
\(\left\{{}\begin{matrix}n_{HClO}=a+b=0,15\left(mol\right)\\n_{CO2}=a+0,5b=\frac{2,24}{22,4}=0,1\left(mol\right)\end{matrix}\right.\Rightarrow\left\{{}\begin{matrix}a=0,05\left(mol\right)\\b=0,1\left(mol\right)\end{matrix}\right.\)
\(\Rightarrow m_{CaOCl2}=0,1.127=12,7\left(g\right)\)
nHClO = 7,875/52,5 = 0,15 mol
Gọi nNaClO = a mol ; nCaOCl2 = b mol
CO2 + NaClO + H2O ----> NaHCO3 + HClO
a a a (mol)
CO2 + 2CaOCl2 + H2O ----> CaCl2 + CaCO3 + 2HClO
0,5b b b (mol)
có nHClO = a + b = 0,15
nCO2 = a + 0,5b = 2,24/22,4 = 0,1
⇒ a = 0,05 ; b = 0,1
⇒ mCaOCl2 = 0,1.127 = 12,7 gam
