Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
As a solution's pH rises, it becomes more acidic.

검증된 단계별 안내

Understand the concept of pH: pH is a measure of the hydrogen ion (H⁺) concentration in a solution. A lower pH indicates a higher concentration of H⁺ ions (more acidic), while a higher pH indicates a lower concentration of H⁺ ions (more basic or alkaline).

Analyze the statement: 'As a solution's pH rises, it becomes more acidic.' A rising pH means the solution is becoming less acidic and more basic, as the H⁺ ion concentration decreases.

Determine the truth of the statement: The statement is false because a rising pH does not indicate increasing acidity; it indicates decreasing acidity and increasing alkalinity.

Correct the false statement: The corrected statement would be, 'As a solution's pH rises, it becomes less acidic and more basic.'

Review the corrected statement to ensure it aligns with the scientific understanding of pH and acidity.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

pH Scale

The pH scale measures the acidity or basicity of a solution, ranging from 0 to 14. A pH of 7 is considered neutral, while values below 7 indicate acidity and values above 7 indicate alkalinity. Understanding the pH scale is essential for interpreting how changes in pH affect a solution's properties.

Acidity and Basicity

Acidity refers to the concentration of hydrogen ions (H+) in a solution, which increases as pH decreases. Conversely, basicity refers to the concentration of hydroxide ions (OH-), which increases as pH rises. This relationship is crucial for understanding how a solution's pH affects its chemical behavior.

Chemical Reactions and pH

Many chemical reactions are pH-dependent, meaning that the rate and direction of these reactions can change with varying pH levels. For example, as a solution's pH rises and becomes more basic, it can alter the solubility and reactivity of certain compounds, impacting overall chemical behavior.
