Acids and Bases Review Extra Credit

Stronger acids are those that-

• hold on to their protons more strongly

• lose their protons more easily

• more completely inhibit polarity in water

• exhibit hydrogen bonding

The conjugate pair for a strong base is—

• Strong base

• Weak Base

• Strong Acid

• Weak Acid

For two acids of equal concentration, the stronger acid has —

• a higher concentration of hydroxide ions

• a higher pH

• a higher concentration of hydronium ions

• a stronger base

What color does litmus paper turn when placed in an acidic solution?

• Black

• Blue

• Green

• Red

In 1923, G.Lewis suggested a simplistic way of describing reactions that did not fit the Bronsted-Lowry definition of acid-base reactions. He suggested that an acid is any species lacking an octet and conversely a base as any species with an unshared pair of electrons.

According to his definitions, all of following can be classified as a base except -

• CH₃^-

• CH₃⁺

• NH₃

• H₂O

Which of the following reactions is between an acid and a base to produce a salt?

• Neutralization

• Combustion

• Half Reaction

• Hydrolysis

When investigating the pH of a solution, what effect is most likely observed when solid ammonium chloride is added to a dilute aqueous solution of NH₃?

• the pH decreases

• the pH becomes 7

• the pH increases

• the pH does not change

If a solution has a hydrogen ion concentration of 1x10^-13 mol/L it is

• an acid

• a base

• a salt solution

• water

When HCl is added to pure water, which of the following will occur?

• the [H+] will increase

• the pH will decrease

• the [OH-] will decrease

• all of the above

The addition of NaOH to pure water will

• Cause the pH to increase.

• Cause the pH to decrease.

• Cause the pH to decrease.

• Produce a salt water solution with no pH.
