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.

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 ...

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.

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 ...

Welcome to science world. Now everyone loves a wee bag of chips, don’t they? Maybe a wee pasty or a battered sausage and if you’ve any sense you’ll cover it in a bit of vinegar. But did you know that ...

IN MANY ways, litmus paper is the perfect scientific sensor. It is cheap, requires no power or skill to use and delivers instant results. Blue paper turns red in acids. Red paper turns blue in alkalis ...
