Active listening occurs whenever you are attentive to the verbal and nonverbal information being shared by a speaker.

REMINDER:  For review purposes, make quick notes of terms and facts, using pen and paper only. You do not have time to write full questions and answers. If you attempt to take pictures of the screen and/or do screen captures, it will cause you to have no grade for the quiz and a grade reduction on Test 4. REMINDER 2:  This, along with notes you make from reading and from the PowerPoint is your only review for Test 4. This quiz and review is designed to help you have review materials from these chapters. Reminder 3:  The following provide some answers following some questions, but not all. Answer ‘True’ and move forward.

Review feminine and masculine communication styles, and the term genderlect.

Which of the following salt compounds will have increased solutility under acidic conditions? Hint:  Consider the acid-base properties of the salts. 

Consider the titration of 20 mL of 0.30 M butanoic acid, HC4H7O2, Ka = 1.5 x 10−5.  What is the pH of the solution after adding 20 mL of 0.25 M NaOH?

Which of the following titrations would produce a solution with a neutral pH at the equivalence point?

A solution contains 2.0 × 10⁻³ M Pb²⁺ and 1.2 × 10⁻³ M I⁻.  Will a precipitate of PbI₂ form in this solution? Hint:  Ksp of PbI₂ = 8.5 × 10⁻⁹

A solution prepared in the lab contains 3.5 × 10⁻⁴ M Sr²⁺ and 0.0010 M F⁻. Will a precipitate of SrF2 form in this solution? Hint:  Ksp of SrF₂ is 4.3 × 10⁻⁹

Consider the following titration curve graphs: Which of the titration curves best represents the results for a strong acid titrated with a strong base?

What is the pH of a buffer made from 0.15 mol of HF and 0.55 mol of KF in 2.0 L of solution? Hint: The Ka of hydrofluoric acid, HF, is 6.8 × 10⁻4.
