Accepted Answer

Methyl amine is not commonly found in household products or antacids. The other options (A-D) are commonly found in household products or antacids.

Question 16

List the acid, base, conjugate acid, and conjugate base, in that order, for the following reaction: CH₃CO₂H(aq) + H₂O(l) ⇌ CH₃CO₂^-(aq) + H₃O⁺(aq)

Accepted Answer

The answer of List the acid, base, conjugate acid, and...

Question 17

The substance Mg(OH)₂(aq) is:

Accepted Answer

Mg(OH)2 is a strong base due to the hydroxide ions (OH-) it produces in solution. The addition of ₂ does not change the fact that it is a strong base.

Question 18

Which of the following is not an attribute of a base?

Accepted Answer

Bases have a bitter taste, while acids taste sour.

Question 19

When the following reaction goes in the reverse direction (from products to reactants), what is the acid? HF(aq) + H₂O(l) ⇌ F^-(aq) + H₃O⁺(aq)

Accepted Answer

In the reverse reaction, H₃O⁺ donates a proton to F^-, acting as the acid.

Question 20

Which of the following statements regarding acids is incorrect?

Accepted Answer

An acid is not always a strong electrolyte. Some acids may only partially ionize in aqueous solution, making them weak electrolytes.
