Acids and Bases fully solved graded A+ 2023/2024

Acids and Bases... - correct answer Acids have the following general properties: Sour taste Ability to dissolve many metals Ability to turn listmus paper red Ability to neutralize bases ... - correct answer Picture is of carboxylic acid chemical group, acids that contain this chemical group are considered carboxylic acids. ex: citric acid, acetic acid, Malic Acid ... - correct answer Bases have the following general properties: bitter taste slippery feel turns listmus paper blue ability to neutralize acids ... - correct answer ARRHENIUS DEFINITION OF ACIDS AND BASES Acid: A substance that produces H+ ions in aqueous solution Base: A substance that produces OH- ions in aqueous solution ... - correct answer HCl is an acid according to the arrhenius definition because when placed in water it ionizes completely to form H+ ions and Cl- ions. In an aqueous solution the H+ ion binds to a water molecule ... - correct answer A water molecule that takes on a hydrogen ion is called a hydronium ion (H3O+) ... - correct answer NaOH is a base according to the Arrhenius definition because it produces OH- ions. When NaOH is added to water, it dissociates into component ions. ... - correct answer Under the arrhenius definition, acids and bases come together to form water, neutralizing each other in the process H+ (aq) + OH- (aq) -- H2O (l) ... - correct answer [Bronsted-Lowry Definition of Acids and Bases] Acid: Donates a H+ ion Base: Accepts a H+ ion ... - correct answer Bronsted Lowry works better for bases that do not have OH- groups (such as ammonia) but accept hydrogen ions. ... - correct answer According to the Bronsted Lowry definition, some substances can act as acids or bases (are called amphoteric) For example: NH3 + H2O --- NH4+ + OH- (base) (acid) Reverse Reaction: NH4+ + OH- --- NH3 + H2O (acid) (Base) In this reaction the the base (NH3) in the forward reaction becomes an acid in the reverse reaction which is an example of a conjugate acid-base pair (two substances related to eachother by the transfer of a proton and must be the same type of acid or base) a conjugate acid is any base to which a proton has been added. A conjugate base is any acid from which a proton has been removed ex
