What is the pOH of a solution with a pH of 4?

• 14

• 10

• 4

• 12

If the [H⁺] concentration of a solution is 1 x 10^-7 M, what is the pH of the solution?

• 7

• 14

• 1

• 0

A solution with a pH of 8.6 would be...

• Acid

• Base

• Neutral

• Acid and Base

Answer explanation

A solution with a pH of 8.6 is considered a Base. Bases have pH values above 7.

What does pH measure?

• Amount of Oxygen Ions

• Amount of Hydrogen Ions

• The amount of salt in a solution

• The density

Answer explanation

pH measures the amount of Hydrogen Ions in a solution, making the correct answer choice 'Amount of Hydrogen Ions'.

When a strong acid and a strong base mix, what are the reactants formed?

• water and ions

• ions

• salt and water

• salt and ions

Answer explanation

When a strong acid and a strong base mix, they form salt and water as the reactants.

a solute whose water solution conducts electricity is called a(n)

• nonconductor

• electrolyte

• nonelectrolyte

• aqueous solution

Answer explanation

An electrolyte is a solute that conducts electricity in a water solution, making it the correct choice.

Solutions in which electric currents cannot run through are said to be

• noncolloidal

• electrolytes

• nonelectrolytes

• conductors

Answer explanation

Solutions in which electric currents cannot run through are called nonelectrolytes, as they do not dissociate into ions to conduct electricity.

This solution would be considered

• Unsaturated
• Supersaturated
• Saturated
• Undefined

How does temperature affect solubility?

• Solubility is not affected by temperature.

• Solubility decreases with an increase in temperature.

• Solubility increases with an increase in temperature.

Answer explanation

Solubility of a substance generally increases with an increase in temperature, as higher temperatures provide more energy for the solvent molecules to break apart and surround the solute particles.

We have 3 cups of orange juice samples, based on the color which one is SATURATED?

• Cup A

• Cup B

• Cup C

• None of the Above

Answer explanation

Cup B is the saturated orange juice sample based on color intensity.
