\(n_{Cl2}=\frac{1,456}{22,4}=0,065\left(mol\right)\)
\(n_{KCl}=\frac{37,25}{74,5}=0,5\left(mol\right)\)
\(PTHH:3Cl_2+6KOH\rightarrow5KCl+KClO_3+3H_2O\)
_______0,065___0,13 ______________
\(\Rightarrow CM_{dd\left(KOH\right)}=\frac{0,13}{0,5}=0,26M\)
PTHH:3Cl2+6KOH→5KCl+KClO3+3H2O
--------0,065--------------0,13 mol
nCl2=1,456\22,4=0,065(mol)
nKCl=37,25\74,5=0,5(mol)
⇒CMddKOH=0,13\0,5=0,26 M
