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 ...

Properties of Acids and Bases: This article is a foundational guide for students to understand acids and bases along with their properties. Here you will learn about the acid and base definition, pH, ...

Pour desired household chemicals into separate 50 mL beakers. Add a few drops of universal indicator OR about 25 mL of red cabbage indicator and mix. Compare colors to standard solutions in lighted ...

A new study has been regarded as "very important" because it offers a new framework for understanding reactions in organic chemistry. In their study, the team addressed the cooperative role of ...

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 ...

Acids are chemical compounds that will ionize in water having a hydrogen ion (H+) active greater than that of water. Acids can give up a proton and they are of two types, it is strong acids and weak ...

Electrons can spur the chemical reaction between an acid and a base, according to new results in Science, a finding that may help researchers precisely control reactions in areas from biology to ...

It is useful to know the colour of some compounds commonly reacted with acids to work out if a colour change has occurred.
