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 ...

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 ...

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 ...

(Higher tier) Strong acids completely ionise in water. They break up completely to produce a high concentration of hydrogen ions in the solution.

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 ...
