Front

What is a titration?

Back

Adding a known amount of solution of known concentration to determine the concentration of an unknown.

Front

What is a Bronsted Lowry base?

Back

A substance that accepts H+ ions.

Front

What do neutralization reactions produce?

Back

A salt and water.

Front

What is the overall reaction for the following steps: Step 1: AB + C2 → ABC + C (slow); Step 2: C + AB → ABC (fast)?

Back

2AB + C2 → 2ABC.

Front

If a compound has a half-life of 14 min, how long will it take for a 12 mol sample to decay to 1.5 mol?

Back

42 min.

Front

Define half-life in the context of chemical reactions.

Back

The time required for half of the reactant to decay or transform into products.

Front

What is the role of an acid in a chemical reaction?

Back

An acid donates H+ ions in a reaction.

Front

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

Back

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

Front

What is the pH scale?

Back

A scale used to measure the acidity or basicity of a solution, ranging from 0 (acidic) to 14 (basic).

Front

What is the formula for calculating pH?

Back

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