STRENGTH VS CONCENTRATION

==Strong & Weak Acids== [image:http://i.imgur.com/C1eKMPs.png] '''Strong Acids''' Strong acids dissociate fully in water. This means that virtually all of the acid particles split into the ions they're made of. Strong acids release a larger number of H+ ions (protons) making the solution more acidic. '''Weak Acids''' Weak acids do not dissociate fully. Only some of the acid particles split into the ions they're made of. Weak acids release fewer H+ ions (protons) forming more weakly acidic solutions. ==Concentration== [image:http://i.imgur.com/kGLbUr4.png?1] Concentration is the amount of solute (something that dissolves) that is dissolved in a certain amount of solvent (usually water) Dissolving more of the substance into a given volume increases the concentration. Adding more of the solvent (e.g.) water reduces the concentration, making the solution more dilute. Concentration should not be confused with amount. Imagine you were making juice from a concentrate (powder or syrup). The instruction might suggest you add one packet to a litre of water. If you used more than one litre of water the drink would be more dilute (less concentrated). If you add more than one packet to a litre the drink would be more concentrated. Once you have made up the drink, whether you pour someone a small glass or a large glass doesn't change the concentration. In this way you can see the difference between concentration and the amount of a solution. [image:http://i.imgur.com/MeQ16Tx.png?1]
