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 ...

Two types of acid-base titration stand out: alkalimetry and acidimetry. Each method provides a precise means to measure compounds based on their acid or basic content, depending on the type of the ...

Neutralisation is the reaction of an acid with a base that results in the pH moving towards 7. It is a useful process that occurs in everyday life such as in the treatment of acid indigestion and 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 ...
