Chemistry 20 BOOTSTRAP EXAMPLE

Since you completed your CHECKLIST for Unit 2 Lesson 3, you are ready to prove to one of the classmates an outcome that no one else has shown yet.

To receive full marks follow the following procedure:

a) Post a new forum and indicate which outcome (found in the bottom) you are showing that no one else has done yet. (1 mark)

b) Make up a question about this outcome (1 mark)

c) Show the detail solution with explanations of each step to obtain your final solution (5 marks)

You can submit this to the class either through any of the following format: video/text/paper & pencil.

d) Once you are done your post, you need to comment on another student in the class and observe if they completed the solution correctly and if it is correct the solution state this, but if it is not then correct their solution (3 marks).

-Recall International Union of Pure and Applied Chemistry (IUPAC) nomenclature of acids and bases

-Recall the empirical definitions of acidic, basic and neutral solutions determined by using indicators, pH and electrical conductivity-Calculate H3O+ (aq) and OH– (aq) concentrations and the pH and pOH of acidic and basic solutions based on logarithmic expressions; i.e., pH = –log[H3O+ ] and pOH = –log[OH– ]
-Use appropriate Système international (SI) units to communicate the concentration of solutions and express pH and concentration answers to the correct number of significant digits; i.e., use the number of decimal places in the pH to determine the number of significant digits of the concentration
-Compare magnitude changes in pH and pOH with changes in concentration for acids and base
-Explain how the use of indicators, pH paper or pH meters can be used to measure H3O+ (aq)
-Define Arrhenius (modified) acids as substances that produce H3O+ (aq) in aqueous solutions and recognize that the definition is limited
-Define Arrhenius (modified) bases as substances that produce OH– (aq) in aqueous solutions and recognize that the definition is limited
-Define neutralization as a reaction between hydronium and hydroxide ions
-Differentiate, qualitatively, between strong and weak acids and between strong and weak bases on the basis of ionization and dissociation; i.e., pH, reaction rate and electrical conductivity
Identify monoprotic and polyprotic acids and bases and compare their ionization/dissociation.
