Answers
Answer:
Explanation:
so here is your answer. I hope you understand that well
Concept:
The ability of a substance, known as a solute, to dissolve in a solvent to form a solution is known as solubility. Ionic compounds that separate into cations and anions in water have a wide range of solubilities.
Given:
Solubility product of AgCl (Ksp) = 2.0 x 10⁻¹⁰ mol² dm⁻⁶
Find:
The solubility product of AgCl is 2.0 x 10⁻¹⁰ mol² dm⁻⁶. The maximum concentration of Ag⁺¹ ions in the solution is?
Solution:
AgCl exist in equilibrium as:
AgCl ⇄ Ag⁺ + Cl⁻
The solubility product can be calculated as:
Ksp = [Ag⁺][Cl⁻]
Let the concentration of silver ions and chloride ions be x.
2.0 x 10⁻¹⁰ mol² dm⁻⁶ = x * x
2.0 x 10⁻¹⁰ mol² dm⁻⁶ = x²
square root of(2.0 x 10⁻¹⁰ mol² dm⁻⁶) = x
1.414 * 10⁻⁵ mol dm⁻³ = x
Therefore, the concentration of silver ions and chloride ions is 1.414 * 10⁻⁵ mol dm⁻³.
Hence, the solubility product of AgCl is 2.0 x 10⁻¹⁰ mol² dm⁻⁶. The maximum concentration of Ag⁺¹ ions in the solution is 1.414 * 10⁻⁵ mol dm⁻³.
