Question 2 of 18, Step 1 of 1 Correct The acidity of a water-based solution is defined as pH = -log[H*], where [H*] is the hydrogen ion concentration, measured in moles per liter. Solutions with a pH- value of less than 7 are acidic: solutions with a pH-value of greater than 7 are basic; solutions with a pH-value of 7 (such as pure water) are neutral. Suppose that you test apple juice and find that the hydrogen ion concentration is [H] = 0.00028. Find the pH-value of the juice. Round your answer to the nearest hundredth. Answer Ke Keyboard Sh

![## Understanding pH and Hydrogen Ion Concentration
In this lesson, we explore how the acidity of a water-based solution is defined using the pH scale. The pH is calculated using the formula:
\[ \text{pH} = -\log [\text{H}^+] \]
where \([\text{H}^+]\) represents the hydrogen ion concentration, measured in moles per liter.
### Key Concepts:
- **Acidic Solutions**: Solutions with a pH value of less than 7.
- **Basic Solutions**: Solutions with a pH value greater than 7.
- **Neutral Solutions**: Solutions with a pH value of exactly 7 (e.g., pure water).
### Problem Example:
Suppose you test apple juice and find that the hydrogen ion concentration is \([\text{H}^+] = 0.00028\).
**Task**: Calculate the pH value of the juice and round your answer to the nearest hundredth.
### Answer:
The pH calculation process involves using the formula provided above to determine the acidity level based on the given hydrogen ion concentration.
