## Understanding pH and Hydrogen Ion ConcentrationIn 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. (Note: There is no visual graph or diagram in this section; it primarily contains textual information and formulas for calculation.)

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
