question 23

No Plagiarism Please! Could someone please Create 2 different acids Models I wrote the formula But do not know how to turn it into a model like the Picture below Popular acid models are Arrhenius model and Bronsted-Lowry model. Arrhenius model According to Arrhenius concept an acid is defined as a substance that contain hydrogen atom and releases hydronium ion in aqueous solution as only cation.         For example HCl is an acid according to Arrhenius concept, as it releases H3O+ ion as cation.          HCl (aq) +H2O (l)---> H3O+(aq) + Cl- (aq) According to Arrhenius concept a base  is defined as a substance that releases hydroxyl ion in aqueous solution as only cation.For example NaOH is a base according to Arrhenius concept, as it releases OH- ion as anion.     NaOH (aq) ----> Na+(aq) + OH-(aq)   Bronsted-Lowry concept  According to this concept an acid is defined as a species that releases proton in aqueous solution and forms it's conjugate base.  According to this concept a…

Identify Bronsted-Lowry acid and base

Calculate the values of [H+] and [OH−] using the pH=3 for Vinegar. An increase in pH ofone unit represents how much decrease in hydrogen ion concentration?
