PS Acids, Bases, and Solutions Test Review

Front

What is the pH of a strong acid like HCl in a 0.001 M solution?

Back

The pH is 3.

Front

What does a high concentration of hydroxide ions (OH-) and a low concentration of hydronium ions (H3O+) indicate about the pH?

Back

It indicates a pH of 12.

Front

What type of mixture is fog?

Back

Fog is a colloid.

Front

Which salt is least soluble at 40°C: KClO3, NaCl, KI, or KNO3?

Back

KClO3 is the least soluble.

Front

How many grams of ammonium chloride are needed to make a saturated solution at 80°C?

Back

65 grams.

Front

Define a strong acid.

Back

A strong acid is one that completely dissociates in solution, releasing all of its hydrogen ions.

Front

What is the difference between a solution and a colloid?

Back

A solution is a homogeneous mixture where the solute is completely dissolved, while a colloid has larger particles that do not settle out.

Front

What is the pH scale range?

Back

The pH scale ranges from 0 to 14.

Front

What is the significance of a pH of 7?

Back

A pH of 7 is considered neutral, meaning the concentrations of H3O+ and OH- are equal.

Front

What is a saturated solution?

Back

A saturated solution is one in which no more solute can dissolve at a given temperature.
