Question

write the balanced dissociation equation for solid copper(ii) sulfide in aqueous solution. if it does not dissociate, simply write only nr. be sure to include the proper phases for all species within the reaction. cus(s)→

Explanation:

Step1: Identify dissociation products

Copper(II) sulfide dissociates into copper(II) ions ($Cu^{2 + }$) and sulfide ions ($S^{2 - }$) in aqueous solution.
$CuS(s)
ightarrow Cu^{2+}(aq)+S^{2 - }(aq)$

Step2: Check charge balance

The charges on both sides of the equation are balanced. The left - hand side has no net charge and on the right - hand side, $+ 2+( - 2)=0$.

Answer:

$CuS(s)
ightarrow Cu^{2+}(aq)+S^{2 - }(aq)$
