Ca(OH)2 + 2HCl \(\rightarrow\) CaCl2 + H2O
2KOH + H2SO4 \(\rightarrow\) K2SO4 + H2O
NaOH + HCl \(\rightarrow\) NaCl + H2O
3 pthh của các pư trung hòa:
\(NaOH+HCl\rightarrow NaCl+H_2O\)
\(HNO_3+Ba\left(OH\right)_2\rightarrow Ba\left(NO_3\right)_2+H_2O\)
\(HCl+KOH\rightarrow KCl+H_2O\)
KOH + HCl ->KCl H2O
NaOH + H2SO4 -> Na2SO4 + H2O
Ca(OH)2 + H2SO4 -> CaSO4 + H2O
KOH + HCl ->KCl + H2O
2NaOH + H2SO4 -> Na2SO4 + 2H2O
Ca(OH)2 + H2SO4 -> CaSO4 + 2H2O
