Answer:

The correct option is: b. pH 6.4-8.0

Explanation:

Phenol red is a weak acid that is used as a pH indicator and exists in the form of stable red crystals.

<u>The color of the phenol red solution changes from yellow to red when the change in pH is observed. The color of phenol red transitions from yellow to red when the pH is 6.8 - 8.2 or 6.4 - 8.0</u>

Above the pH of 8.2, the phenol red solution turns a bright pink in color.

Potassium sulfate is added to water. The equation that best represents this process
Anastaziya [24]

The equation that best represents the addition of potassium sulfate to water is K_2SO_4(s) -- > 2 K^+ (aq) + SO4^{2-} (aq)

<h3>Dissolution of potassium sulfate in water</h3>

When potassium sulfate is dissolved in water, it dissociates into its cation and anion according to the following equation:

K_2SO_4(s) -- > 2 K^+ (aq) + SO4^{2-} (aq)

The positive ions are 2 moles of potassium ions while the negative ion is a mole of sulfate ion.

What term describes a solution in which the dissolved solute is in equilibrium with the undissolved solute?
Airida [17]

Saturated solution refer to a solution in which the dissolved solute is in equilibrium with the undissolved solute.

<h3>What is a saturated solution?</h3>

A saturated solution is a chemical solution that contain maximum amount of a solute which is dissolved in the solvent. The addition of anotheg solute will not dissolve in a saturated solution. The amount of solute that can be dissolved in a solvent to form a saturated solution depends on a variety of factors.

Therefore, Saturated solution refer to a solution in which the dissolved solute is in equilibrium with the undissolved solute
