Final answer:
The solubility product (Ksp) for Ag2SO4 is expressed as Ksp = [Ag+]²[SO4²-], which accounts for the ions produced upon dissolution of Ag2SO4 into Ag+ and SO4²2- in solution.
Step-by-step explanation:
The expression for the solubility product (Ksp) for silver sulfate (Ag2SO4) involves the dissolution of Ag2SO4 into its ions in a solution. The balanced dissolution reaction is:
Ag2SO4(s) ⇌ 2Ag+(aq) + SO42-(aq)
From this, the Ksp expression is written as:
Ksp = [Ag+]2[SO42-]
where [Ag+] represents the molar concentration of silver ions and [SO42-] represents the molar concentration of sulfate ions in the solution. The charges of the ions are critical in writing the Ksp expression correctly.
