Question

Consider the reaction when aqueous solutions of nickel(ii) nitrate and potassium hydroxide are combined. (use the solubility rules provided in the owl preparation page to determine the solubility of compounds.) the net ionic equation for this reaction is:

Answer 1

Answer : When we combined the aqueous solutions of nickel nitrate and potassium hydroxide a displacement reaction will occur.

The whole reaction is explained below:-

`Ni(NO _(3)) _(2) + 2 KOH ----\ \textgreater \ Ni(OH) _(2) + 2 [KNO _(3) ].`

Now according to the OWL preparation page soluibility rules the compounds that are included in the reactants are perfectly soluble and hence undergo a displacement reaction yielding a precipitate at the completion of reaction.

The net ionic equation of the reaction is :


`Ni ^((+2)) _((aq.)) + 2 OH ^((-)) _((aq.)) ----\ \textgreater \ Ni (OH) _(2) _((s))`
