An acid is

A.

a compound that removes H+ ions from a solution

B.

a compound that releases OH- ions into a solution

C.

a compound that releases H+ ions into a solution

Answer and Explanation

The Correct Answer is C

A. A compound that removes H+ ions from a solution: This describes a base, since bases decrease hydrogen ion concentration by binding or neutralizing H+ ions, which is the opposite of what acids do.

B. A compound that releases OH- ions into a solution: This also characterizes a base, such as sodium hydroxide, which increases hydroxide ion concentration rather than contributing hydrogen ions.

C. A compound that releases H+ ions into a solution: Acids are substances that increase the hydrogen ion concentration in a solution by releasing H+ ions, making the solution more acidic and lowering its pH.

Correct Answer is False

Explanation

False: A buffer is defined by its ability to resist pH changes, not by holding the pH specifically at 7. Buffers can maintain stability at various pH levels, such as blood buffers at ~7.4 or gastric buffers at acidic ranges.

Correct Answer is B

Explanation

A. Aquatic: Aquatic refers to environments or organisms related to water, but it does not describe a chemical process in which bonds are broken.

B. Hydrolysis: Hydrolysis is the reaction where water is used to split covalent bonds, breaking larger molecules into smaller subunits. This process is common in digestion and cellular metabolism.

C. Dehydration (or condensation): Dehydration involves removing water to form covalent bonds between molecules, which is the opposite of hydrolysis and results in larger compounds.

D. Hydratic: Hydratic is not a recognized term in chemistry for describing bond-breaking reactions, and it does not apply to hydrolytic processes.
