Question

write the chemical equation, ionic equation and net ionic equation for the reaction between aqueaous sodium sulfide and aqueouus copper(II) nitrate. (aqueous is dissolved in water)

Answer 1

What are the ions present in the mixture? Which ones can react to form a solid?

Answer 2

positive ions are sodium and copper
negative ions are sulfur and nitrogen
But i dont know which one can react to form a solid??

Answer 3

Solubility table

Answer 4

Copper cations would bond with Sulphide anions giving a precipitate of Copper Sulphide.

Chemical equation:
\[Na _{2}S +CuSO _{4}\rightarrow CuS +Na _{2}SO _{4}\]
Total ionic equation:
\[2Na ^{+}+S ^{2-}+Cu ^{2+}+SO _{4} ^{2-} \rightarrow CuS+2Na ^{+}+SO _{4} ^{2-} \]
Net ionic equation:
\[Cu ^{2+}+S ^{2-} \rightarrow CuS\]
