Answer:
2.29x10⁻¹² is Ksp of the salt
Explanation:
The Ksp of the metal hydroxide is:
M(OH)₂(s) ⇄ M²⁺ + 2OH⁻
Ksp = [M²⁺] [OH⁻]²
As you can see in the reaction, 2 moles of OH⁻ are produced per mole of M²⁺. It is possible to find [OH⁻] with pH, thus:
pOH = 14- pH
pOH = 14 - 10.22
pOH = 3.78
pOH = -log[OH⁻]
<em>1.66x10⁻⁴ = [OH⁻]</em>
And [M²⁺] is the half of [OH⁻], <em>[M²⁺] = 8.30x10⁻⁵</em>
<em />
Replacing in Ksp formula:
Ksp = [8.30x10⁻⁵] [1.66x10⁻⁴]²
Ksp = 2.29x10⁻¹² is Ksp of the salt
Answer:
<h2>
<u>Suspension.</u></h2>
Explanation:
Since the particles of a suspension are larger than those of solutions and are insoluble, they settle to the bottom of the container over time. Therefore, suspensions need to be shaken to ensure that the solute particles are evenly distributed throughout the mixture.
