M-U7-Z3 Flashcard

Front

What is a strong base?

Back

A strong base is a substance that completely dissociates in water to produce hydroxide ions (OH-) and metal ions.

Front

What is a conjugate acid?

Back

A conjugate acid is the species formed when a base gains a proton (H+).

Front

What is the order of acid strength from strongest to weakest for the following: hydrocyanic, hypochlorous, citric, acetic?

Back

The order from strongest to weakest is: acetic, citric, hypochlorous, hydrocyanic.

Front

What does it mean for an acid to dissociate?

Back

Dissociation of an acid refers to the process where the acid breaks apart into its ions in solution.

Front

What is a conjugate base?

Back

A conjugate base is the species that remains after an acid donates a proton (H+).

Front

How do you identify a stronger acid?

Back

A stronger acid dissociates more completely in solution, producing more H+ ions.

Front

What is the difference between a strong acid and a weak acid?

Back

A strong acid completely dissociates in solution, while a weak acid only partially dissociates.

Front

What is the role of water in acid-base reactions?

Back

Water can act as both an acid and a base, participating in the transfer of protons (H+).

Front

What is the significance of the pH scale?

Back

The pH scale measures the acidity or basicity of a solution, with lower values indicating higher acidity.

Front

What is the formula for calculating pH?

Back

pH = -log[H+], where [H+] is the concentration of hydrogen ions in moles per liter.
