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 ...

When an acid is neutralised, it forms a salt. Making salts Acids react with metals, bases and carbonates to produce salts. Neutralisation is the reaction between an acid and a base. Titration and ...

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 ...

Sodium hydroxide is added to a cylinder of aluminum nitrate, precipitating out aluminum hydroxide. When additional base is added, the precipitate dissolves. The reactions can then be reversed with the ...

This reaction is shown below. In this reaction the ferric ion (Fe 3+) is acting as a Lewis Acid and the oxalate anion (C 2 O 4 2-) as a Lewis Base. A Lewis Acid is an electron pair acceptor and a ...
