Teaching chemistry necessitates hands-on activities to help students deeply understand chemistry concepts and relate scientific principles to daily life. However, constraints in accessing laboratory ...

An acid–base titrator connected to the Internet was developed for conducting remote investigative experiments. The experiment was broadcasted in a high school senior classroom, with the presence of a ...

Is it an acid, base, or neutral? Make your own acid-base indicator from red cabbage, then test various household substances. Acids and bases are classes of materials that have different properties.

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 ...

Colourful indicators from flower petals at the House of Science. Photo: SUPPLIED This week we conclude our home chemistry series with a lovely colourful experiment. The background Acid-base chemistry ...

A crash course on the basic differences between acids and bases. A crash course on the basic differences between acids and bases, complete with a classroom-friendly experiment demonstrating the ...

When titrated by a strong base such as 0.1 M NaOH solution, a solution of citric acid traverses a buffer region during which the pH of the solution climbs gradually then more steeply. From about one ...

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 ...

Nearly everything at [HAD] is at least based on science in some way or another. If, however, you would like to do some actual scientific experiments with stuff around the house, [Observationsblog] ...

ABSTRACT: This study investigated a natural indicator for acid-base titration which is extracted from guinea corn leaves popularly called “waakye leaves” in Ghana. Four types of acid-base titration ...
