Acid Base Reactions Acid An acid is a substance which donates proton in water solution. They turn litmus red and form salts when they react with bases.They have PH less than 7. Examples: Nitric acid Nitrous acid Sulphuric acid Base A substance which accepts proton in water solution is called base. Bases turn litmus red and form salts when react with acids. They have PH greater than 7. Examples: Sodium Hydroxide Sodium bicarbonate Magnecium hydroxide Acid Base Reaction A chemical reaction that happens between an acid and base is called acid base reaction. The OH(-) anion of base when combines with H(+) of acid, a salt is formed. The compound that formed by the reaction of anion and cation…show more content…
Arrhenius Theory The Arrhenius theory of acids and bases was initially suggested by the Swedish chemist Svante Arrhenius in 1884. He recommended classifying specific compounds as acids or bases based on what kind of ions made when the compound was added to water. Arrhenius Acid Any species that rises the protons and concentration H(+) ions in aqueous solution called Arrhenius acid. For example, the dissociation reaction of HCl in water: HCl → H+ + Cl- When an aqueous solution of hydrochloric acid is made, HCl dissociates into H+ and Cl- ions, resulting in an increase in the concentration of H+ ions in solution so HCl is an Arrhenius acid Arrhenious Base It is defined as any species that increases the concentration of hydroxide ions, in aqueous solution. Highly soluble sodium hydroxide is the Arrhenius Base. Sodium hydroxide dissociates in water as follows: In water, sodium hydroxide completely dissociates to form H+ and OH- ions resulting in increase in the concentration of hydroxide ions. Therefore, NaOH is an Arrhenius base. Common Arrhenius bases contain other Group 1 and Group 2 hydroxides like LiOH and
