PTHH ( I ) : \(2NaCl+2H_2O\rightarrow2NaOH+H_2+Cl_2\)
\(n_{NaCl}=C_{MNaCl}.m_{ddNaCl}=1.0,2=0,2\left(mol\right)\)
- Theo PTHH ( I ) : \(n_{NaOH}=n_{NaCl}=0,2\left(mol\right)\)
PTHH ( II ) : \(NaOH+HCl\rightarrow NaCl+H_2O\)
- Theo PTHH ( II ) : \(n_{HCl}=n_{NaOH}=0,2\left(mol\right)\)
Mà\(n_{HCl}=C_{MHCl}.V_{HCl}=2V_{HCl}\left(mol\right)\)
=> \(2V_{HCl}=0,2\)
=> \(V_{HCl}=0,1\left(l\right)=100\left(ml\right)\)
PT( I ): 2NaCl+2H2O→2NaOH+H2+Cl2
nNaCl=1.0,2=0,2(mol)
- Theo PT ( I ) : nNaOH=nNaCl=0,2(mol)
PT( II ) : NaOH+HCl→NaCl+H2O
- Theo PT ( II ) : nHCl=nNaOH=0,2(mol)
Mà nHCl=CMHCl.VHCl=2VHCl(mol)
=> 2VHCl=0,2
=> VHCl=0,1(l)=100(ml)
