Here are also some interesting “lab”-based topics/questions from 5 steps: Lab cookies which are also posted on the AP Chem Resources link
Good luck on Monday! I will be rooting for you! Remember to breathe….answer all the questions you know first, answer the questions you know but will take a bit longer next, leave the ones you are not sure about last. Answer ALL the mc questions–narrow down your options and make your best guess if necessary! Answer the free response questions clearly, showing calculations clearly and justifying your answers where necessary.
1. Lab 20G Part 4: Find the Ka of a weak monoprotic acid. To do this, you will need to measure the pH of your weak acid. By doing a titration against NaOH, you will calculate the initial molarity of the weak acid. Fill in your Ka table and find the equilibrium concentrations of all your species. Ta da! Calculate the Ka.
Lab 20G – all parts due next class.
Note: Test coming up soon!
Goal Day is on Tues. May 5. Any incomplete assignments or retests should be completed on/by that day.
1. Go over Worksheet: “Coulombic Attraction” – any Questions?
2. I will be able to explain how the size of the atom, ionization energy, and electron affinity change across the periodic table and down the periodic table. See class scribblings here: Coulombic Attraction student notes and Zeff
3. Finish reading section 8.2 and 8.3 and do Q# 31-39, 45, 51, 53
