Acids and bases powerpoint presentation | Teaching Resources If both the acid and the base are strong,– that is, they both completely dissociate in water – for example, the reaction between nitric acid and sodium hydroxide can be written: HNO3(aq) + NaOH(aq) NaNO3(aq) + H2O(aq) • This can also be written as: H+(aq)+ NO3-(aq) + Na+(aq) + OH-(aq) Na+(aq) + NO3-(aq) + H20(l) • We can remove the spectator ions to leave us with: H20(l) H+(aq) + OH-(aq). tie together concepts of acids and bases and equilibrium weak acids and, Chapter 14: Acids and Bases - . • As water is a weak acid, its conjugate bases is strong, so the position of equilibrium lies very much to the right. With indicators • If a base is insoluble in water, for example copper (II) oxide (CuO), then there will be no reaction with indicators. Definitions of Acids and Bases An acid is a substance that breaks into ions in an aqueous solution.

Key Math Skills . Identifying Acids and Bases Acids have a ph from 0-7 Lower pH value indicates a stronger acid. • The electric field around it is so intense that it attracts any molecule with unshared electrons, such as H2O • The reaction H+ + H2O H3O+ was shown to liberate 1300kJ mol-1. See our Privacy Policy and User Agreement for details. • The most accurate way to determine pH is to use a pH meter 0.1 moldm-3 HCl(aq) pH = 1.0 0.1 moldm-3 CH3COOH(aq) pH = 2.9, Conductivity measurement • Strong acids and strong bases in solution will give much higher readings on a conductivity meter than equimolar (equal concentration) solutions of weak acids or bases, because they contain more ions in solution • Using Universal indicator • Strong acids produce a red colourwith universal indicator weak acids produce orange/yellow colours • Strong bases produce a purple colourwith U.I. jennie l. borders. • For example: HCl(g) H+(aq) + Cl-(aq) HNO3(aq) H+(aq) + NO3-(aq). Acid-Base Equilibrium Chapter 18 Acids and Bases Arrhenius acids: generate H+ in water bases: generate OH- in water Brønsted-Lowry acids: H+ donors bases: H+ acceptors HCl + H2O Cl + H3O+ acid base Conjugate acid-base pairs Conjugate base: remains after H+ is lost acid: HCl conj. Arrhenius definitions. General Properties of Acids and Bases. If the H in a solution is 1 x 10-1 mol/dm3, If the hydrogen ion concentration is 10-7 M, what. What is transferred between a conjugate acid-base, What is the term used to describe a substance, In the reaction NH4 H2O ? general principles of catalysis. toxicology is the study of how natural and man made poisons cause undesirable effects in living, Chapter 18 Equilibria Involving Acids & bases - . Chemistry—Ch. HCl + NH3 Cl- + NH4+ acid base conjugate base conjugate acid, Water as an acid and a base • HCl can donate a proton to water, so that water acts as a base.

The history of acid-base theory • There have been many attempts to define acids and bases. ACIDS AND BASES IONIC EQUILIBRIA - . Metal carbonate + acid salt + water + carbon dioxide Metal hydrogen carbonate + acid salt + water + carbon dioxide • All carbonates and hydrogen carbonates will neutralize acids to produce carbon dioxide andwater. Learning about Acids & Bases . • This is called complete dissociation. It was noted, As work proceeded, doubt was cast on the very existence of, The Lewis definition of a base includes the Brønsted-Lowry, Acids that completely dissociate into ions in aqueous, Experiments to distinguish between strong and weak acids and, Acid – base reactions and Le Chatelier’s principle, If both the acid and the base are strong,– that is, they, The nitrate ions and the sodium ions are ‘spectator, Displacement of ammonia from ammonium salts, The equilibrium lies very much on the right, so a single, The equilibrium lies very much over to the left hand side, Each H2O that dissociates (splits up) gives rise to one H+. Which type of solution is one with a pH of 8? dna rna. • Neutralization of acids • Displacement of ammonia from ammonium salts • With indicators, Displacement of ammonia from ammonium salts NH4Cl(s) + NaOH(aq)NaCl(aq) + NH3(g) + H2O(l) • Ammonia is very soluble in water, so it may be formed in solution, or, if small amounts of sodium hydroxide are added to solid ammonium chloride, it can be collected as a gas.

Chapter 2 - . • OH- • NH3 • H2O • Cl-, The Lewis definition of acids and Bases • There are reactions which appear to us, on common-sense grounds, to be acid-base reactions, and which do not come within the scope of the Brønsted-Lowry definition. It was noted that, while hydrochloric acid conducts electricity, pure hydrogen chloride does not. weak bases produce a blue colour, Observation from reaction • Reacting an acid with a carbonate or a hydrogen carbonate will produce carbon dioxide gas . Acids taste SOUR Lemons, vinegar Compounds that have Hydrogen (H+) as their cation. On the pH scale: • The smaller the pH, the greater the concentration of H+ (aq) • A difference of one pH number means a tenfold difference in acidity, so that pH 2 is ten times as acidic as pH 3 • pH measures alkalinity as well as acidity, because as [H+(aq)] goes up, [OH-(aq)] goes down.
