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 ...

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.

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.

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 ...

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 ...
