Question

What reaction might we use to synthesize nickel sulfate,niso4? Write equations for acid base neutralization. Include states in your answer. And write the equations of acid with carbonate. Include states in your answer.

Answer 1

Here's what I get

Step-by-step explanation:

1. Nickel sulfate

base + acid ⟶ salt + water

NiSO₄ is a salt of the base Ni(OH)₂ and the acid sulfuric acid.

Hydroxides of transition metals are insoluble; most sulfates are soluble.

`\underbrace{\hbox{Ni(OH)$_(2)$(s)}}_{\hbox{base}} + \underbrace{\hbox{H$_(2)$SO$_(4)$(aq)}}_{\hbox{acid}} \longrightarrow \, \underbrace{\hbox{NiSO$_(4)$(aq)}}_{\hbox{salt}} + \underbrace{\hbox{2H$_(2)$O(l)}}_{\hbox{water}}`

2. Carbonate + acid

Most carbonates are insoluble.

They react with acids to form carbonic acid (H₂CO₃), which decomposes into water and carbon dioxide.

`\rm NiCO_(3)(s) + H_(2)SO_(4)(aq) \longrightarrow \, NiSO_(4)(aq) + H_(2)O(l) + CO_(2)(g)`
