Chemical formula of sodium hydroxide = NaOH
Chemical formula of Nickel (II) Chloride = NiCl₂
The product is a solid compound of Ni²⁺ ions and hydroxide ions.
So the compound formed is Nickel (II) Hydroxide.
Chemical formula of Nickel (II) Hydroxide = Ni(OH)₂.
Since a double displacement reaction occurs, the other product should be NaCl.
The balanced chemical molecular equation for the reaction is thus
NiCl₂ + NaOH → Ni(OH)₂ + NaCl.
