The pH Scale and Neutralization Essentials

What does the pH scale measure?

• The concentration of hydrogen ions in a solution

• The temperature of a solution

• The alkalinity of a solution

• The viscosity of a solution

Which pH value represents a neutral solution?

• 0

• 7

• 14

• 10

What property is common to all acids?

• They turn litmus paper blue

• They have a slippery feel

• They taste sour

• They react with metals to form gases

Which of the following is a common indicator for testing pH?

• Bromine water

• Litmus paper

• Salt solution

• Sugar solution

What is a neutralization reaction?

• A reaction between an acid and a base producing water and a salt

• A reaction where an acid cancels out the effect of a base

• A reaction that neutralizes the temperature of a solution

• A reaction that only produces water
