Which of the substances of the formula which are given react with sodium hydroxide solution: CaO, Cu (OH) 2, H2So4, Co2, CuSo4, KCL, CuO, HCL. Write an equation for feasible reactions.
2NaOH + H2SO4 = Na2SO4 + 2H2O
CO2 + NaOH = NaHCO3
2NaOH + CuSO4 = Na2SO4 + Cu (OH) 2 (precipitate)
NaOH + HCl = NaCl + H2O
Answer: H2So4, Сo2, CuSo4, HCL
