Several theories have been developed to explain the behaviour of acids and bases. The most notable theories include the Arrhenius concept, the Brønsted-Lowry theory, and the Lewis concept. In the ...

SIOUX CITY (KTIV) - Gather your supplies! In this episode we will use everyday materials to explore pH and how it changes between acids and bases. Blackberries contain a chemical class called ...

A well-established technique, acid-base titration is an analytical method used to determine the concentration of an unknown acid or base. In practice, it involves adding a solution of known strength ...

An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...

This lab includes a theoretical explanation of how buffers work and how they are made, including a derivation of the Henderson-Hasselbalch equation. Students will use what they have learned to ...

Carbonic Acid Structure: Acids and Bases are an integral part of chemistry and a major portion is devoted to explaining their properties and examples. One of the most studied acids is Carbon Acid. It ...

The pH scale measures the acidity or alkalinity of a substance, ranging from 0 to 14, with values below 7 representing acidity, above 7 representing alkalinity, and 7 representing neutrality.

Students will be able to explain that if two substances cause turn a pH indicator different colors, they must be different substances. Students will be able to explain that the color that a substance ...
