acid base review

Which compound is NOT an electrolyte?

• NH₃

• CH₃OH

• KBr

• HCl

According to Arrhenius theory a substance that is classified as an acid will always yield

• H⁺

• K⁺

• F^-

• OH^-

A solution of base differs from an acid in that the base

• conducts electricity

• causes an indicator to change color

• has greater hydronium ion concentration

• has greater hydroxide ion concentration

A sample of pure water contains

• neither H⁺ or OH^- ions

• equal concentration of H⁺ and OH^- ions

• a larger concentration of H⁺ than OH^- ions

• a smaller concentration of H⁺ than OH^- ions

As .1M HCl is added to .1M KOH, the pH of the basic solution

• increases

• decreases

• remains the same

As the H₃O⁺ ion concentration of a solution decreases, and the OH^- ion concentration increases, the pH of the solution

• remains the same

• decreases

• increases

When tested, a solution turns red litmus blue. This indicates that the solution contains more

• hydronium than hydroxide

• hydroxide than hydronium

• hydrogen than hydronium

• hydrogen than hydroxide

An indicator was used to test a water sample with a pH of 12. Which indicator color would be observed

• colorless with litmus

• red with litmus

• colorless with phenolphthalien

• pink with phenolphthalien

• A only

• B only

• A and B

• neither A nor B

• it acts as a base and accepts a proton

• it acts as a base and donates a proton

• it acts as an acid and accepts a proton

• it acts as a acid and donates a proton
