10.6 End-of-Chapter Material
Chapter Summary To ensure that you understand the material in this chapter, you should review the meanings of the bold terms in the following summary and ask yourself how they relate to the topics in the chapter. The earliest chemical definition of an acid, the Arrhenius definition, says that an acid is a compound that Read more »
10.4 The Strengths of Acids and Bases
Learning Objectives Describe the difference between strong and weak acids and bases. Describe how a chemical reaction reaches chemical equilibrium. Define the pH scale and use it to describe acids and bases. Acids and bases do not all demonstrate the same degree of chemical activity in solution. Different acids and bases have different strengths. Strong Read more »
10.3 Water: Both an Acid and a Base
10.3 Water: Both an Acid and a Base Learning Objective Write chemical equations for water acting as an acid and as a base. Water (H2O) is an interesting compound in many respects. Here, we will consider its ability to behave as an acid or a base. In some circumstances, a water molecule will accept a Read more »
10.2 Brønsted-Lowry Definition of Acids and Bases
10.2 Brønsted-Lowry Definition of Acids and Bases Learning Objectives Recognize a compound as a Brønsted-Lowry acid or a Brønsted-Lowry base. Illustrate the proton transfer process that defines a Brønsted-Lowry acid-base reaction. Ammonia (NH3) increases the hydroxide ion concentration in aqueous solution by reacting with water rather than releasing hydroxide ions directly. In fact, the Arrhenius Read more »
10.1 Arrhenius Definition of Acids and Bases
10.1 Arrhenius Definition of Acids and Bases Learning Objective Recognize a compound as an Arrhenius acid or an Arrhenius base. One way to define a class of compounds is by describing the various characteristics its members have in common. In the case of the compounds known as acids, the common characteristics include a sour taste, Read more »
9.2 Concentration
9.2 Concentration Learning Objectives Express the amount of solute in a solution in various concentration units. Use molarity to determine quantities in chemical reactions. Determine the resulting concentration of a diluted solution. To define a solution precisely, we need to state its concentration: how much solute is dissolved in a certain amount of solvent. Words Read more »
8.5 End-of-Chapter Material
Chapter Summary To ensure that you understand the material in this chapter, you should review the meanings of the following bold terms in the following summary and ask yourself how they relate to the topics in the chapter. A phase is a certain form of matter that has the same physical properties throughout. Three phases Read more »
6.6 End-of-Chapter Material
Chapter Summary To ensure that you understand the material in this chapter, you should review the meanings of the following bold terms in the following summary and ask yourself how they relate to the topics in the chapter. Chemical reactions relate quantities of reactants and products. Chemists use the mole unit to represent 6.022 × Read more »
6.5 Mole-Mass and Mass-Mass Problems
Learning Objectives Convert from mass or moles of one substance to mass or moles of another substance in a chemical reaction. We have established that a balanced chemical equation is balanced in terms of moles as well as atoms or molecules. We have used balanced equations to set up ratios, now in terms of moles Read more »
5.7 End-of-Chapter Material
Chapter Summary To ensure that you understand the material in this chapter, you should review the meanings of the following bold terms in the following summary and ask yourself how they relate to the topics in the chapter. Scientific laws are general statements that apply to a wide variety of circumstances. One important law in Read more »
