What process is illustrated below? S(s) ⇌H2O⇌ S (aq)
Decomposition of a solid
Melting of a solid
Formation of saturated solution of a solid
Sublimation of a solid
Correct answer is C
From the given equation:
\(S_{(s)} ⇌ S_{(aq)}\) (in the presence of (\(H_2O\))
The solid form has changed to an aqueous solution upon dissolution in water. Due to the presence of the reversible reaction arrow ⇌, the solution (aqueous) formed is saturated, this is because a saturated solution is an equilibrium system
