Unit 14 Review R

Front

What is the pH scale?

Back

The pH scale measures the acidity or basicity of a solution, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What does a high concentration of OH- ions indicate?

Back

A high concentration of OH- ions indicates that the solution is basic.

Front

What is the chemical formula for water?

Back

The chemical formula for water is H2O.

Front

What is a neutralization reaction?

Back

A neutralization reaction is a chemical reaction between an acid and a base that produces water and a salt.

Front

What is the pH of a neutral solution?

Back

The pH of a neutral solution is 7.

Front

What is the pH of a strong base like NaOH?

Back

The pH of a strong base like NaOH can be significantly higher than 7, often above 12.

Front

What happens to H+ and OH- ions in a neutralization reaction?

Back

In a neutralization reaction, H+ ions from the acid combine with OH- ions from the base to form water.

Front

What is the relationship between H+ and OH- concentrations in an acidic solution?

Back

In an acidic solution, the concentration of H+ ions is greater than that of OH- ions.

Front

What is the relationship between H+ and OH- concentrations in a basic solution?

Back

In a basic solution, the concentration of OH- ions is greater than that of H+ ions.

Front

What is the effect of dilution on the pH of a strong acid?

Back

Diluting a strong acid decreases its concentration of H+ ions, which can increase the pH towards neutral.
