Answer 2

Answer:

The ionic strength of 0.1 M MgSO₄ is 0.4

Let's understand about ionic strength and how to calculate it.

Explanation:

What is the ionic strength of solutions?

The ionic strength of a solution is determined by the quantity of ion concentration in the solution. It is expressed as I.

• It has an effect on ion activity.
• It is signified by the interaction of the ion with water and other ions in the solution.
• The ionic strength formula is used to calculate half of the total concentration of each ionic species.

The formula for ionic strength is attached as an image:

Here,

Ci = ionic concentration

Zi = ion charges

Now, using the knowledge gained above, let us attempt to answer the provided question.

First of all, the ions in MgSO₄ are Mg²⁺ and SO₄²⁻

For Mg²⁺, Zi = 2, Ci = 0.1

and, for SO₄²⁻, Zi = 2, Ci = 0.1

So, Z² for Mg²⁺ and SO₄²⁻ are 4 and 4 respectively.

The ionic strength (I) may be calculated using the given formula,

I = $\frac{1}{2}$ (0.1 x 4 + 0.1 x 1)

I = $\frac{1}{2}$ (0.8)

I = 0.4

Hope, the concept is clear.
