Question 1 of 10

1. Question
1 point(s)
Mathematically, how is pH defined based on the concentration of hydrogen ions [H⁺]?
- pH = log [H⁺]
- pH = -log [H⁺]
- pH = -log [OH⁻]
- pH = 14 – [H⁺]
Correct

Incorrect
Question 2 of 10

2. Question
1 point(s)
What will happen to the pH value of an acidic solution if the concentration of hydrogen ions [H⁺] increases?
- The pH value will become greater than 14.
- The pH value will decrease.
- The pH value will remain constant at 7.
- The pH value will increase.
Correct

Incorrect
Question 7 of 10

7. Question
1 point(s)
If the concentration of hydroxide ions [OH⁻] in a solution increases, what will be the effect on the degree of alkalinity of the solution?
- The degree of alkalinity increases and the pH value increases.
- The alkalinity increases but the pH value decreases.
- There is no change in the alkalinity.
- The alkalinity decreases and the pH value becomes 7.
Correct

Incorrect
Question 8 of 10

8. Question
1 point(s)
How is a universal indicator used to determine the pH value of a solution?
- Counts the number of indicator dots used.
- The pH value is read directly from the scale on the indicator bottle.
- Measures the temperature of the solution after the indicator is added.
- The resulting color is compared to a standard color chart.
