This mixture of a weak acid (HA) and it's conjugate base (A^-) acts as a buffer. A buffer is a solution with a highly stable pH. On addition of small amounts of either a strong acid ...

Use Brady's Reagent (2,4-DNPH) to test for the presence of the C=O bond in a carbonyl compound. The formation of a yellow precipitate indicates a positive test result. Then determine the melting point ...

This is the minimum amount of energy reacting particles must have to undergo a chemical reaction.

In order for a reaction to occur, particles must 1. COLLIDE with each other 2. with sufficient KINETIC ENERGY (energy greater than or equal to the ACTIVATION ENERGY). This is known as Collision Theory....
