Acids and Bases. Chapter 7 Acids and Bases. 7.1 The Nature of Acids and Bases. 7.2 Acid Strength. 7.3 The pH Scale. 7.4 Calculating the pH of Strong Acid Solutions. 7.5 Calculating the pH of weak Acid Solutions. 7.6 Bases. 7.7 Polyprotic Acids. 7.8 Acid-Base Properties of Salts. 7.9 Acid Solutions in Which Water
Definitions of acids and bases;; Bronsted's conjugate acid-base pairs concept;; Determination of [H3O+], [OH-], and pH for strong acids and strong bases;; Determination of [H3O+], [OH-], pH, Ka, or Kb, and percent ionization for weak acids and weak bases;; Predicting acid/base properties of salts (ionic compounds) and
perform calculations involving ionic equilibria. • understand the components of buffer solutions and how they work to resist changes in pH. SUGGESTED REVIEW AND EXTERNAL READING. • data analysis review; relevant textbook information on acids, bases, salts, and buffers. BACKGROUND. Weak acids and bases in
Understanding the titration curve. Maximum buffer capacity. [HA] = [A. -. ]. When we have a buffer we can use the Hendersen-Hasselbach equation. This is nice since it is the simplest treatment of the acid-base equilibrium. In the case shown we have pH = pK a . Added [OH. -. ] = 1/2 [HA]. 0
Acids, Bases and Salts. 2. CHAPTER. You have learnt in your previous classes that the sour and bitter tastes of food are due to acids and bases, respectively, . Can you now write the equations for the reactions you have observed? . Metal carbonate/Metal hydrogencarbonate + Acid > Salt + Carbon dioxide + Water.
Acids and Bases. Three Theories; pH and pOH; Titrations and Buffers. Recommended reading. M.S. Silberberg, Chemistry, The Molecular Nature of Matter and Change. Acids and A base reacts with a protonic acid to give water (and a salt) . Calculate the concentration of OH- for an aqueous solution with a pH of 9.60.
Examples of compounds are water, carbon dioxide, sucrose and sodium chloride (and other salts) and inorganic acids and bases such as HCl and NaOH. The formula unit of an ionic compound states the type of different ions present, written with no charge symbol, and the number of each ion, expressed as the ratio of the
We are about to learn that a couple of equally simple equations will provide estimates of pH or pOH for two categories of compounds—and Strong acids: HCl. Weak acids: acetic insoluble salts like sulfides. Strong bases: NaOH. Weak bases: ammonium molecules like CO2. Soluble salts: NaCl. Sparingly soluble salts.
Chapter 16: Acids, Bases, and Salts. Key topics: pH scale BrOnsted Acids and Bases. Acid: proton donor. Base: proton acceptor acid/base reaction: proton transfer. Each side of the reaction has an acid and a base ! Conjugate base: what . Therefore the pH is easy to calculate: the concentration of. [H+] or [OH–] is just
acids, bases or salts. In this unit we shall categorize these substances. We shall study about their characteristic properties. We will also be learning about pH – a .. (white ppt.) If excess of carbon dioxide gas is passed through lime water, the white precipitate of calcium carbonate disappears due to the formation of water
