1.6 Energy changes in chemical reactions
... Chemists deal with matter on a macroscopic scale in the laboratory, but explain its behaviour in terms of atoms and molecules. This requires a wide range of distances (see Figure 1.4). You will need to become familiar with the multiplication prefixes in Table 1.3 used to describe lengths on atomic a ...

... A neutral solution must have [H+] = = 7.00 The pH of solution is the negative logarithm of the hydronium ion concentration. That is: pH = - log[H+] Hence if H+ concentration is 1 x 10-3 then pH = 3 Acidic solutions are defined to have pH < 7 Basic (alkaline) solutions are defined to have pH > 7 Neut ...
