Start the following in class:

1. Use the PQ5R or SQ5R method to prepare study guide for text section 11.3 on Reactions in Aqueous Solutions or go to https://socratic.org/chemistry to research the topics brought up in section 11.3 of your text.  Read section 11.3 in your chemistry text, pages 342 through 346, and as you do, create a study guide using the SQ5R or PQ5R method explained in class and on the distributed handout packet. For section 11.3, take notes not only on Net Ionic Equations and on Predicting the Formation of a Precipitate, but also on Table 11.3 [Solubility Rules for Ionic Compounds] on page 344 of your text.  You may record vocabulary entries in the body of your study guide, or you may check them off on the chapter 11 vocabulary list as you think about the meanings of the terms and add any notations to the vocabulary list for clarifications sake.

1b.  Writing in blue or black ink, place your hand in number in a circle followed by your name in the upper right white space of a piece of three holed composition paper in your learning log that hasn’t been written on.  Place the page reference for the problems to be considered to the left of the red marginal line on the first blue line.  Centered on the first blue line, write a descriptive title for the learning activity such as Section [chapter #.section#] Responses.  Before you write your response to each question or problem listed below, write its designation to the left of the red marginal line as listed below, followed by your response in ink to the right of the marginal line.

  • Study Conceptual Problem 11.9 on page 343 and then show your work including tallies of all atoms occurring in the initial and final states for practice problems I11-28 (In chapter 11, problem 28) and I11-29ab.
  • In the Section Assessment 11.3 on page 344, read, analyze, and do practice problems I11-30 and I11-31 and show your work including tallies of all atoms occurring in the initial and final states for practice problems I11-32abcd, I11-33abc and I11-33a’b’c’, I11-34abcde, and I11-35abcd and I11-35-a’b’c’d’. [The prime symbol (‘) after the letter of each sub problem represents the second piece of information required to completely answer each sub problem.
  • After you are finished, check page R91 of the text and check each of those problems that you can by writing in either a check mark (√) or a correction in green ink as we do in class.  Some questions do not have a suggested response given.  For each such question, circle the number of the question in the margin of your notebook paper and check your response with that of your classmates when you come to class.

2.a. In your Journal Notebook write your journal entry on sheets of three holed 8.5 inch by 11 inch ruled paper.

  • In the upper right corner white space of each upward facing page, use a blue or black pen to write your hand in number within a circle followed by your name.
  • To the left of the marginal line, print J94B and circle it.
  • Each journal entry should either be at least a paragraph of exemplary writing and penmanship concerning a single topic, or be a concept map relating chemistry terms. Begin each day’s paragraph with a topic sentence, follow with explained instances, and close with a focused summary statement.
  • Read the handout subtitled How to Construct Net Ionic Equations.  [This handout is toward the end of the larger Chemical Reactions handout packet of which it is a part.]  Label a sheet of paper in your journal notebook with the title, Net Ionic Equations.
  • The required journal focus topic J94A for today is:

a. According to this reading selection, what is a spectator ion?

b. According to this reading selection, what is a net ionic equation?

c. According to this reading selection, how would one go about checking for a balance of charge?

d. According to this reading selection, what is the advantage of writing a net ionic equation?

2.b. In your Journal Notebook write your journal entry on sheets of three holed 8.5 inch by 11 inch ruled paper.

  • In the upper right corner white space of each upward facing page, use a blue or black pen to write your hand in number within a circle followed by your name.
  • To the left of the marginal line, print J94B and circle it.
  • Each journal entry should either be at least a paragraph of exemplary writing and penmanship concerning a single topic, or be a concept map relating chemistry terms. Begin each day’s paragraph with a topic sentence, follow with explained instances, and close with a focused summary statement.
  • Refer to page 342 in your text for an explanation of what a complete ionic equation is.  The required journal focus topics, J94B, for today are:

.              a. What does a complete ionic equation show that the regular formula unit expression does not show?

b. Construct a balanced formula unit expression for the double replacement reaction between lead (II) nitrate aqueous solution and potassium iodide aqueous solution that produces lead (II) iodide precipitate and potassium nitrate aqueous solution.

c. Write the complete ionic equation for the double replacement reaction between lead (II) nitrate aqueous solution and potassium iodide aqueous solution that produces lead (II) iodide precipitate and potassium nitrate aqueous solution.

d. Write the net ionic equation for the double replacement reaction between lead (II) nitrate aqueous solution and potassium iodide aqueous solution that produces lead (II) iodide precipitate and potassium nitrate aqueous solution.

Recommended for those who have time left in their 45 minute study period, but not required of all: 

  1. Download the current ActivInspire unit flipchart by logging on to the MNSD Google Drive and selecting it from the Student Resources > ActivInspire  > Unit 7 > Types of Chemical Reactions > Types of Chemical Reactions.  Generally the flipchart name will begin with a capital U and end in a relatively high version number following the v at the end of the flipchart’s title.
