Water: The Universal Solvent

One of the most valuable properties of water is its ability to dissolve. An individual water molecule has a bent shape with a H-O-H bond angle of approximately 105 degrees. Water is polar thus having positive & negative partial charges on its ends. Water: The Universal Solvent.

Chapter 4

Chapter 4. You must become familiar with: 1.) the precipitation diagram (fig. 4.3) before you can write precipitation reactions. Chapter 4. 2.) The charges of the transition metal ions in solution (figure 4.2). 3.) Strong acids and bases (figure 4.1) if you are to write acid-base equations.

Chapter 4 Reactions in Aqueous Solutions

Chapter 4 Reactions in Aqueous Solutions. Many chemical and almost all biological reactions occur in the aqueous medium Substances (solutes) that dissolve in water (solvent) can be divided into two categories: Electrolytes Non-Electrolytes. Three Major Types of Reactions.

Double Replacement Reactions

Double Replacement Reactions. Double Replacement Reactions. Double Replacement Reactions occur when a metallic ion replaces another metallic ion in a compound and a nonmetal replaces a nonmetal in a compound, or when an acid reacts with a base. Compound + compound ? new compound+ new compound

Net Ionic Equations

Net Ionic Equations. Just the important stuff. Precipitation Reactions. This concept applies to any reaction with an aqueous reactant, but it's easiest to see in precipitation reactions. Let's start with an example one: NaCl (aq) + AgNO 3 (aq) ? AgCl (s) + NaNO 3 (aq).

Double Replacement Reactions

Double Replacement Reactions. In detail. Ionic Compounds in Water. Because the ions in ionic compounds are attracted (not connected) to each other ionic compounds can dissociate in water. We can write the dissociated ions like this: Na + + Cl - + K + + NO 3 - ?
