Salt lowers the freezing/melting point of water, so in both cases the idea is to take advantage of the lower melting point. Ice forms when the temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius).
The molecule of mixture cannot be seen hence, it will be considered as homogeneous mixture.
<h3>
What is molecule?</h3>
A molecule is just a collection of more than two atoms bound together by chemical bonds; depending on the context, the phrase doesn't have to include ions that meet this requirement.
<h3>
What is homogeneous mixture?</h3>
Solids, liquids, as well as gases, can all be homogeneous mixtures. Through, they have almost the same look and chemical makeup.
When sugar will be dissolved, the sucrose molecules get separated from one another. The materials that make up individual molecules stay together like sucrose molecules sucrose molecules, so the molecule will not break up.
Therefore mixture can be considered as molecule and homogeneous mixture.

They are joined by a triple covalent bond.
The Ksp of the solution is 1.97 * 10^-9.
<h3>What is the pH?</h3>
The pH is defined as the hydrogen ion concentration of the solution. Now we have the pH of the solution as 10.9.
We know that;
pOH = 14 - pH
pOH = 14 - 10.9
pOH = 3.1
[OH^-] = Antilog [-3.1]
[OH^-] =7.9 * 10^-4 M
Now
Ksp = [M^2+] [2OH^-]^2
Ksp = s * (2s)^2
Ksp = 4s^3
Now s = 7.9 * 10^-4 M
Ksp = 4(7.9 * 10^-4)^3
Ksp = 1.97 * 10^-9
