Question

Scrieti ecuatiile de hidroliza a ZnCl2si NCl in forma moleculara ,ionica si ionica redusa si indica reactia mediului
Va rooooooooooog urgeeeeeeeeeeeeent dau coroana

Answer 1

ZnCl2 + 2H2O---> 2HCl + Zn(OH)2↓

Zn²⁺Cl⁻2 + 2H⁺OH⁻---> 2H⁺Cl ⁻+ Zn(OH)2

Zn²⁺+2OH⁻---> Zn(OH)2      mediul este acid

NaCl + H2O---> HCl+NaOH

Na⁺Cl⁻ + H⁺OH⁻---->H⁺Cl⁻+Na⁺OH⁻   mediu neutru
