Give four major unfavourable effects of acid rain. (4 marks) Give four ways in which acid rain and the problems associated with it could be solved or at least helped (4 marks) 13.45 mL of 0.200 M NaOH is required to titrate 25.0 mL of a solution which is known to have HCl. Calculate the original [HCl].
To form an acid anhydride, a water molecule is lost in a condensation reaction between two carboxylic acids. This is why acid anhydrides are called anhydride – lack of water. Reactions of Acid Anhydrides. Acid anhydrides react in a similar way to acyl chlorides, but they are less reactive.
Chapter 4 Practice Worksheet: Reactions in Aqueous Solutions. List the three general classes of chemical reactions: precipitation, acid-base neutralization, and redox reactions. How can you identify each of the three reaction types above (e.g., what characteristic defines each one?)?
Classify each formula as an acid anhydride, basic anhydride, strong acid, weak acid, strong, or weak base. For each formula write an equation to show how it reacts with water.
Reactions of Acid Anhydrides The chemistry of acid anhydrides is similar to that of acid chlorides, although anhydrides react more slowly. Thus, acid anhydrides react with water to form acids, with alcohols to form esters, with amines to form amides, and with LiAlH 4 to form primary alcohols.
CHEM1102 Worksheet 8: Acids and Bases. Model 1: pH. Water is able to act as both an acid and a base and it is possible for water to react with itself in an acid-base reaction called the autoprotolysis or autoionization of water: H2O(l) + H2O(l) H3O+(aq) + OH-(aq)
Lesson 1: Arrhenius Acids and Bases. 1. Use Table K and Table L to help you identify the rules for determining whether a substance is an acid, a base, or a salt based on the formula. Underline all the acids, circle bases, and box in salts purple. Leave the covalent substances alone.
