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.

Acid/base indicators are described and used to identify substances as acids or bases. Indicators and the pH Scale: Acid/base indicators are described and used to identify substances as acids or bases.

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 ...

in 1909 S.P.L Sorenson, a Danish biochemist devised a scale known as pH to represents the H + ion concentration of an aqueous solution. The pH value of any solution is a number that simply represents ...

Watch this video to see how a salt can be produced in the lab by neutralising sulfuric acid with a metal carbonate, in this case copper carbonate. Here are some ways neutralisation is used: Farmers ...

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 ...

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 ...

Acids and alkalis are not only found in chemistry labs, they are actually very common. We use acids and alkalis in our daily lives for things like cleaning, cooking and you even eat and drink some ...
