PTHH: \(2NaOH+H_2SO_4\rightarrow Na_2SO_4+2H_2O\)
\(n_{H_2SO_4}=C_M.V=0,2.0,5=0,1\left(mol\right)\)
\(n_{NaOH}=2n_{H_2SO_4}=0,2\left(mol\right)\)
\(\Rightarrow V_{NaOH}=\dfrac{n}{V}=\dfrac{0,2}{0,5}=0,4\left(l\right)\)
\(n_{H_2SO_4}=0,2.0,5=0,1\left(mol\right)\)
PTHH: 2NaOH + H2SO4 → Na2SO4 + 2H2O
Mol: 0,2 0,1
\(V_{ddNaOH}=\dfrac{0,2}{0,5}=0,4\left(l\right)\)
