Chapter 10 - Solutions, Mixtures, and pH

Front

What does pH measure in a solution?

Back

pH measures the inverse amount of hydronium (H₃O⁺) ions in a solution.

Front

What is the formula for hydroxide ion?

Back

The formula for hydroxide ion is OH⁻.

Front

What are the characteristics of a base?

Back

A base has a very bitter taste, feels slippery to the touch, and produces OH⁻ ions when dissolved in water.

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is one with such small particles that you cannot see the individual particles.

Front

What are indicators in chemistry?

Back

Indicators are substances that change color or properties in response to the presence of acids or bases.

Front

What is the pH scale range?

Back

The pH scale ranges from 0 to 14, with 7 being neutral.

Front

What is an acid?

Back

An acid is a substance that donates protons (H⁺ ions) in a solution.

Front

What is a base?

Back

A base is a substance that accepts protons (H⁺ ions) or produces OH⁻ ions in a solution.

Front

What is a suspension?

Back

A suspension is a heterogeneous mixture where the particles are large enough to settle out over time.

Front

What is the difference between a solution and a mixture?

Back

A solution is a homogeneous mixture where one substance is dissolved in another, while a mixture can be heterogeneous.
