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.

Explanation:

Step1: Identify the compound

Copper(II) sulfide has the formula CuS.

Step2: Write dissociation

In aqueous solution, CuS dissociates into its ions. The balanced dissociation equation is:
CuS(s) $
ightleftharpoons$ Cu$^{2 + }$(aq)+S$^{2 - }$(aq)

Answer:

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