| February 17, 2021 | education
We draw up the reaction equation, put down the coefficients:
2NaOH + ZnCl₂ = Zn (OH) ₂ + 2NaCl;
NaOH – alkali, a substance soluble in water.
ZnCl₂ is a water-soluble salt.
NaCl is a water-soluble salt.
Zn (OH) ₂ is a base insoluble in water.
Therefore, a sign of the progress of the reaction of mixing sodium hydroxide and zinc chloride is the formation of a Zn (OH) ₂ precipitate.
