A pH value of 0 to 7 indicates what kind of solution?

A pH value of 0 to 7 indicates an acidic solution. On the pH scale, which ranges from 0 to 14, values below 7 represent acidity. The lower the pH value, the stronger the acidity. For example, a solution with a pH of 1 is highly acidic, whereas a pH of 6 is still acidic but less so. When the pH is exactly 7, the solution is neutral, indicating a balance between H⁺ ions (acidic) and OH⁻ ions (basic). Values greater than 7 indicate a basic or alkaline solution. Understanding this scale is essential in wastewater management, as the acidity of a solution can affect chemical processes and the effectiveness of wastewater treatment.
