Question

Sunt corecte aceste reacți de schimb?
NaOH+HCl -> NaCl+H2O
NaOH+H2SO4 -> NaSO4+H2O
Ca(OH)2+HCl -> NaCl+H2O
Ca(OH)2+H2SO4 -> NaSO4+H2O
MgO+HCl -> MgCl+H2O​

Answer 1

Răspuns:

NaOH + HCl -> NaCl + H2O

2NaOH + H2SO4 -> Na2SO4 + 2H2O

Ca(OH)2 + 2HCl -> 2NaCl + 2H2O

Ca(OH)2 + H2SO4 -> CaSO4 + 2H2O

MgO + 2HCl -> MgCl2 + H2O
