To probe the acid–base chemistry of both sides of the water surface, Colussi and co-workers monitored the deprotonation of a carboxylic acid (RCOOH, with R = C 5 H 11; Fig. 1a): the aqueous ...

In this review, we report ascorbic acid-catalyzed reactions in organic synthesis. Several examples are included in this review to demonstrate that ascorbic acid is a versatile catalyst for the ...

A solution with a pH between 5 and 7 is neutral, 8 or higher is a base, and 4 or lower is an acid. Lime juice, lemon juice and vinegar are acids, so they should have turned the indicator solution ...

Label a piece of paper Acid, Base, and Control. Break off a few leaves of the cabbage. Then the leaves up and put them into a zip-closing plastic bag. Add about 1 cup of water, get as much air out as ...

Adding an acid increases the concentration of H 3 O + ions in the solution. Adding a base decreases the concentration of H 3 O + ions in the solution. An acid and a base are like chemical opposites.

For SQA National 5 Chemistry, learn about the properties of acids and bases and how to tell them apart with this BBC Bitesize Scotland revision guide.

The pH scale . The pH scale shows how acidic a substance is. Learn what pH means and how it is measured in this KS3 chemistry guide from BBC Bitesize.

This article explains whether vinegar is an acid (acidic) or base (alkaline) and whether it matters. While it's known that vinegars are acidic, some people claim that certain types have an ...

Diagnosis of Acid-Base Disorders. Your doctor may order blood tests to measure the pH and carbon dioxide levels in your blood. The blood sample is usually taken from an artery in your wrist.
