An aqueous (water) solution of zinc chloride is weakly acidic.
When zinc chloride dissolves in water, it tends to react with the water (hydrolysis) to form a zinc tetrahydrate[Zn(H2O)4]2+ ion and chloride Cl- ions.
From this tertrahydrate ion partially one proton is hydrolyse (split off in water) which makes it a weak acid:
[Zn(H2O)4]2+ + H2O <<--> [Zn(OH)(H2O)3]+(aq) + H3O+
This can be repeated once in slightly basic pH:
[Zn(OH)(H2O)3]+ + (OH)- --> [Zn(OH)2(H2O)2](s) + H2O
In strong alkali solution this precipitate will dissolve as zincate anion:[Zn(OH)2(H2O)2]s + 2OH- --> [Zn(OH)4]2-(aq)

∙ 12y agoNo, actually it is a amphoteric oxide:
Basic nature:
ZnO + 2 H+ ----> Zn2+ + H2O
Acidic nature:
ZnO + 2 OH- + H2O ----> Zn(OH)4-2

Copper I Chloride is CuCl and Copper II Chloride CuCl2
Is copper chloride a mixture?
No, copper chloride is a pure substance.
Is copper chloride mixture?
No, copper chloride is a pure substance.
Copper chloride chemical formula?
Copper I Chloride is CuCl - Copper II Chloride (the most probable one) CuCl2
What is the compound name for CuCl3?
Copper (III) chloride. Note that this is theoretical compound copper does have a +3 oxidation stae in some complexes but does not from compounds such as CuCl3. The only halides known are +1 oxdtn state:- CuCl, CuBr, CuI +2 oxdtn state : CuF2, CuCl2, CuBr2
Is benzalkonium chloride acid or alkali?
alkali
What is the chemical formula for copper (II) chloride?
There are two kinds of copper chloride. Copper(I) chloride is CuCl. Copper(II) chloride is CuCl2.
Why is copper oxide a base but not an alkali?
Copper oxide is unsoluble in water. A requirement for an alkali is: a soluble base. So copper oxide is a base but not an alkali.
Is copper chloride liquid?
No. Copper(I) chloride and copper(II) chloride are both ionic solids.
Is Copper(II) Chloride?
No. Copper(I) chloride and copper(II) chloride are both ionic solids.
What is copper chloride split into by electrolysis?
copper + Chlorine = copper chloride
What is the formulas for the compounds called copper1 chloride and copper 2 chloride?
Copper I Chloride is CuCl and Copper II Chloride CuCl2

No
Copper oxide+chloride+copper chloride?
CuCl2.
Is copper chloride mixture?
No, copper chloride is a pure substance.
Is copper chloride a mixture?
No, copper chloride is a pure substance.
What happens when copper chloride is mixed with sodium hydroxide?
Copper chloride + Sodium hydroxide --> Copper hydroxide + sodium chloride
