Precipitation reactions often produce brilliant colors. Look at the photographs of each precipitation reaction and write molecular, complete ionic, and net ionic equations for each one.
(a) The precipitation reaction that occurs when aqueous iron(III) nitrate is added to aqueous sodium hydroxide.
(b) The precipitation reaction that occurs when aqueous cobalt(II) chloride is added to aqueous potassium hydroxide.
(c) The precipitation reaction that occurs when aqueous AgNO3 is added to aqueous sodium iodide.
th th Chapter 7 from “Introductory Chemistry” by Zumdahl and Decoste, 7 /8 edition *Majority of the chemical reactions that take place in our bodies occur in aqueous solutions Ex: oxygen dissolving into blood stream Pg 137. PREDICTING IF A REACTION WILL HAPPEN Driving Force: “changes that make reactions go in the direction of the arrow,” the cause of the product Most common driving forces: 1. Forms a solid 2. Forms of water 3. Transfers electrons 4. Forms a gas -if two or more chemicals are joined together and any of these happened, there most likely is a chemical reaction REACTION: SOLID FORMS Precipitation: process by which a solid is formed Precipitate: the solid formed
