pH Scale: Acids, bases, pH and buffers (article) | Khan Academy
The pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). Since the scale is based on pH values, it is logarithmic, meaning that a change of 1 pH unit corresponds to a ten-fold change …
The pH scale (video) | Acids and bases | Khan Academy
The pH scale is a convenient way to represent the acidity or basicity of a solution. We can calculate the pH of a solution by taking the negative logarithm of the hydronium ion concentration, or pH = -log …
pH, pOH, and the pH scale (article) | Khan Academy
Converting [H +] to pH is a convenient way to gauge the relative acidity or basicity of a solution. The pH scale allows us to easily rank different substances by their pH value.
Introduction to pH (video) | Khan Academy
The pH scale is used to determine the acidity or basicity (alkalinity) of a substance. Acidic substances have pH values below 7, while basic substances have pH values above 7; neutral substances have a …
Definition of pH (video) | Khan Academy
Introduction to pH and the pH scale. Examples of calculating pH of pure water, bleach, and orange juice.
The pH scale (apply) (practice) | Khan Academy
Apply your understanding of acids, bases, and the pH scale in this set of free, standards-aligned practice questions.
The pH scale (video) | Acids and bases | Khan Academy
pH measures how acidic or basic a solution is based on the relative amount of charged hydrogen atoms (H⁺) present. The pH scale ranges from 0 to 14, with acids below 7, bases above 7, and neutral …
pH, acids, and bases review (article) | Khan Academy
The pH scale is used to rank solutions in terms of how acidic or how basic they are. It indicates the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution.
