pH

The video tutorial explains the pH scale, which ranges from 0 to 14, with 7 being neutral, 0 very acidic, and 14 very alkaline. It discusses the origin of the term 'pH', which stands for hydrogen potential, and how pH indicates the concentration of hydrogen ions in a solution.

What does a pH value of 7 indicate about a solution?

• It is neutral.

• It is very acidic.

• It is highly concentrated.

• It is very alkaline.

Which pH value would suggest a solution is very alkaline?

• 0

• 7

• 14

• 7.5

What does the 'p' in 'pH' stand for?

• Power

• Potential

• Percentage

• Pressure

The term 'pH' is derived from which of the following?

• Hydrogen power

• Hydrogen percentage

• Hydrogen potential

• Hydrogen pressure

What does the pH level indicate about a solution?

• The volume of the solution

• The concentration of hydrogen ions

• The temperature of the solution

• The color of the solution
