What is the reaction of cobalt nitrate with water?

Answer 1

Yes!

Remember this, when a metal oxide reacts with an acid, two things are produced:

1. salt
2. water

So.......

When cobalt oxide reacts with hydrochloric acid, cobalt chloride and water are formed.

Answer 2

Co(NO3)2 + 2 HCl = CoCl2 + 2 HNO3

Double displacement reaction

Answer 3

Co(No3)2(aq) + 2 NaOH(aq) --> 2 NaNo3(aq) + Co(OH)2(s)

This is also a precipitation reaction because cobalt 2 hydroxide is insoluble

Answer 4

One fairly likely reaction is CoO + 2 HCl => CoCl2 + H2O.

Answer 5

The reaction is:
CoCl2 + 2 NaOH = Co(OH)2 + 2 NaCl
Cobalt(II) hydroxide is a white precipitate.

Answer 6

Cobalt nitrate is soluble and dissociated in water.
