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 ...

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 the complete titration procedure used to investigate how well a buffer resists changes in pH. Prepare a buffer solution by accurately calculating and measuring the required amounts ...

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 ...

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 ...

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 ...

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.

Discover which foods are acidic or alkaline and the science behind the alkaline diet. Learn about their health impacts and the dietary recommendations for various foods.

Introduction You might have done experiments with well-labeled acids and bases in school, but have you ever wondered whether a certain food or chemical around the house is an acid or a base? You can ...

Vinegar is acidic because of its low PH. Consuming it doesn’t affect your body’s natural pH levels, which stay stable unless you have an underlying medical condition. Vinegars are versatile liquids ...
