Answer :
lead (II) sulfate (PbSO.) is more soluble in the water among the given pair.
What is called compound?
- In chemistry, a compound is a substance made up of two or more different chemical elements combined in a fixed ratio.
- When the elements come together, they react with each other and form chemical bonds that are difficult to break.
- These bonds form as a result of sharing or exchanging electrons between atoms.
The given pair includes silver chloride (AgCl) and lead(II) sulfate (PbSO.) . They both produce an equal number of ions upon dissociation in water, that is, two ions.
From Appendix C, it is observed that the Ksp value of AgCI is 1.8x10⁻¹° , and the Ksp value of PbSO4 is 1.6 × 10⁻⁸.
The Ksp of PbSO4 is higher than that of AgCI . Thus, the PbSO4 has a higher solubility in water than that of AgCI .
Hence, lead (II) sulfate (PbSO.) is more soluble in the water among the given pair.
