Составьте уровнение реакции: 1) к купруму (2) сульфат добавьте натрий гидроксид, потом добавьте сульфатную кислоту, а также напишите уравнение того что получается при нагревании
Ответ учителя по предмету Химия
Ответ:
CuSO₄ + 2NaOH = Cu(OH)₂ + Na₂SO₄
1)Cu(OH)2+H2SO4—> CuSO4+2H2O
2) Na2SO4+H2SO4=2NaHSO4
ты не написал(а) к какому веществу добавлять сульфатную кислоту так что я написала 2 реакцию и ты не написал(а) какое вещество нагревать)
