Answer:

Ksp = 1.64 ×10⁻⁵

Explanation:

Given data:

Mass of  Ag₂SO₄ = 5.0 g

Volume of water = 1.0 L

Solubility product = Ksp = ?

Solution:

First of all we will calculate the molarity.

Molarity = Number of moles of solute / Volume of solution in L

Number of moles = mass/ molar mass

Number of moles = 5.0 g/311.74 g/mol

Number of moles = 0.016 mol

Molarity = 0.016 mol / 1 L

Molarity = 0.016 M

Dissociation equation:

Ag₂SO₄  ⇔  2Ag⁺ + SO₄²⁻

Ksp = [Ag⁺]² [SO₄²⁻]

Ksp = [0.032]²[0.016]

Ksp = 1.64 ×10⁻⁵

9. What are the advantages of using an indicator to inform pH measurements? What are the advantages of using a pH meter?
Llana [10]

Answer:

The advantages of using an indicator to inform pH measurements:

It gives a mathematically result of the pH, in addition, it gives the precise pH of solvent, and it also gives an idea of the straight of the solution also.

Now, the advantage of using a pH meter:

It is a rapid method to characterize between acids, bases. However, this method does not show how strong acid or base actually are, plus it tends to gives a range of acidity or basicity not quite accurate as a result.
