Question

describe the ph scale and what it measures.

Explanation:

The pH scale is a measure of how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7 is neutral. Values below 7 are acidic, and values above 7 are basic. It measures the concentration of hydrogen ions (\(H^+\)) in a solution. Mathematically, \(pH = -\log[H^+]\), where \([H^+]\) is the molar concentration of hydrogen ions.

Answer:

The pH scale is a measure of acidity or basicity. It ranges from 0 (most acidic) to 14 (most basic), with 7 being neutral. It measures the concentration of hydrogen ions (\(H^+\)) in a solution, calculated as \(pH = -\log[H^+]\).
