predict the products and write a balanced equation NiCl2(aq)+NaOH(aq)→−−−+−−−?

##"NiCl"_2("aq)" + "NaOH(aq)"####rarr####"Ni(OH)"_2"(s)" + "NaOH(aq")##

This is a double replacement (double displacement) reaction in which the cations and anions of the two reactants switch places. It can be represented by the following example:

AX + BY##rarr##AY + BX

Where A and B are cations and X and Y are anions.

We can now predict the products of this reaction.

##"NiCl"_2("aq)" + "NaOH(aq)"####rarr####"Ni(OH)"_2"(s)" + "NaOH(aq")##
