Document Summary

Electrolytes dissolve in water forming an anion and cation. Strong acids like hcl and nacl dissociate completely in water. Something which dissociates in water and gives up h+ is an acid it donates a h. A base dissociates into oh- and accepts the proton. In above: naoh is the base because it dissociated into oh and accepted a proton. The hcl dissociated into the h which was given to the oh. The result is forming water and ionic salt. Organic acids tend to be weak acids and do not dissociate completely. They exist in equilibrium between their dissociated and non-dissociated forms. We can use the dissociation equation to determine the relative strength of acids based on how much they dissociate. The higher the dissociation value, the stronger the acid. An indicator that an organic compound is an acid is the presence of carboxylate (cooh) or phosphate (po4).
