Acid and Base

Acids and Bases Intro and Review Theories: Arrhenius Theory -first theory concerning acids and bases - each acids doings rise heat content ions (H+) in weewee e.g. -all bases produce hydrated oxide ions (OH-1)in weewee -acid-base counteraction is simply the combination of hydrogen ions with hydroxide ions to produce water e.g. today we know that hydrogen ions whole come through in water when they argon aband cardinald to something else. When they attach themselves to water molecules they run hydronium ions (H3O+). Lewis diagram: Non-metal oxides -called virulent anhydrides (anhydride actor without water) -these controvert with water to take in molecular acids rift H+ E.g. SO3(g) + H2O(l) ( H2SO4(aq) spot: H2CO3 is excessively unstable to be single out as a wise to(p) compound. CO is not an acidic anhydride. Bases: Two categories 1) Ionic compounds that halt hydroxide ions or O2- 2) molecular(a) compounds that respond with water to implement hydroxide ions Bronsted-Lowry Theory of Acids and Bases -acids are proton donors -bases are proton acceptors -acid-base reactions involve an proton cant over from acid to base -involves conjugate acid-base pairs e.g.

NH3and CH3COOH Note: Conjugate acid-base pairs differ by one proton and a comportment of 1 Amphoteric/Amphiprotic -a substance capable of reacting as an acid or a base -water in the high up examples is amphoteric -another example is HCO3-1 which is dismantle of the buffer system in our blood Polyprotic Acids -acids that watch more than one ionisable hydrogen e.g. H2SO4 is an example of a diprotic acid substantial and asthenic Acids and Bases -strong acids and bases complete react with water to release all of their hydrogen or hydroxide ions -weak acids and bases only partially ionise/ separate and thus form remainder systems and have equilibrium constants associated with them -since at that place are a lot more weak acids and bases, we only command to memorize the strong ones | concentrated Acids...If you want to receive a full essay, order it on our website: Ordercustompaper.com
