The pH is a negative logarithmic scale, which measures the molar concentration of hydrogen ions from 1 to 10 14 ions. It therefore has no unit of measurement. Numbers on a negative logarithmic scale ...

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 hydroxycarboxylic acids form very stable complexes with metal ions. In alkaline solution, both the carboxylic and the alcoholic hydroxyl groups take part in complex formation. For the calculation ...

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 ...

Water molecules can break down into hydrogen ions and hydroxide ions. \(H_{2}O(l)\rightleftharpoons H^{+}(aq)+OH^{-}(aq)\) This is a reversible reaction. A small proportion of water molecules break up ...

New computer calculations have revealed that a century-long assumption in chemistry is wrong. At the crux of the matter is the movement of the hydroxide ion, OH –, in water. Hydroxide ions and protons ...

During the London Olympics, significant information came to light that is important in terms of our health and athletic performance. Exercise Induced Metabolic Acidosis or EIMA, focuses on excess ...

Make an acid-base indicator. Dr Yan uses some very colourful science to find out what's acidic in his kitchen. Take 1/4 red cabbage. Finely slice the cabbage. Put all the chopped-up cabbage into a ...

Introduction Did you know that the juices in your stomach are nearly as acidic as lemon juice? Fortunately, your stomach has special cells that act as a barrier to the acid, preventing it from ...
