pH

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

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

• It is slightly acidic.

• It is strongly alkaline.

• It is neutral.

• It is strongly acidic.

Which pH value represents a strongly acidic solution?

• 0

• 10

• 7

• 14

What does a pH value of 14 signify?

• The solution is neutral.

• The solution is slightly acidic.

• The solution is slightly alkaline.

• The solution is strongly alkaline.

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

• Percentage of Hydrogen

• Presence of Hydrogen

• Potential of Hydrogen

• Power of Hydrogen

What does the pH scale measure in a solution?

• The concentration of oxygen ions

• The concentration of hydrogen ions

• The concentration of carbon ions

• The concentration of nitrogen ions
