The pH of aqueous solutions can be measured with a glass electrode and a pH meter or a color-changing indicator. Measurements of pH are important in chemistry, agronomy, medicine, water …

Dec 5, 2025 · A pH value is the quantitative measure of the acidity or basicity of aqueous or other liquid solutions. The term, widely used in chemistry, biology, and agronomy, translates the values of the …

Aug 2, 2025 · pH measures the concentration of hydrogen ions (H⁺) in a solution and indicates whether a solution is acidic, neutral, or basic. The pH scale typically ranges from 0 to 14, where 7 is neutral, …

Jun 10, 2025 · pH is a measure of how acidic or basic a solution is, from 0 to 14. pH is important for chemical reactions in areas like medicine, cooking, and agriculture. Scientists use pH meters and …

This article explains the concept of pH, how to find and calculate the pH, and how the pH formula and pH equation are used in chemistry!

pH is a scale used to measure the acidity or basicity of a solution. It ranges from 0 to 14 and reflects the relative concentration of hydrogen ions (H⁺) and hydroxide ions (OH⁻) in aqueous solutions.

Explore the meaning of pH and how it relates to acidity and basicity. Learn how to calculate pH, pOH, [H₃O⁺], and [OH⁻], and understand what pH tells you about a solution.

The pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is …

Apr 20, 2023 · pH is defined as the negative log of hydrogen ion concentration. It can be used to describe the relative acidity (or basicity) of a solution. Because it is based on a logarithmic scale, a …

pH values above 7 are commonly referred to as “basic” (or “alkaline”). These common terms engender confusion, because a pH value does not directly reflect a quantitative measure of the concentration …
