Any Q’s? Check your answers to the worksheets either from this website (Acid #1 WS) or from the internet (i.e. AP Scoring Guidelines)
Prelab 20D and more! Make a GIANT table with the columns: acid, base, salt, relative pH, hydrolysis equation. Copy the salts from Lab 20D in the lab manual into the “salt” column. What acid and base did the salt form from? Predict whether the salt will be acidic or basic. Write out a hydrolysis equation that supports your prediction. See copy of lab here: Lab 20D
Stories around the “Campfire”
Over Christmas break: Download as many AP Exams as you can so you have them handy. Download any useful AP Resources:
a) Under “Updates”, there is a tab labeled “AP Chem Resources” where you will find a list of websites, practice exams, etc…
Students wrote a mid-chapter Qu-est on sections 16.1-16.5, and 16.11.
More review of Ka and Kb calculations –> you can do more questions from the textbook OR try the sample AP questions from 2009 (Q#1) and 2014 (Q#2). You may not be able to answer all the parts to the question as we have not finished the unit on acids and bases yet!
Test on sections 16.1-16.5, 16.11 on Monday. Main topics covered are properties of acids and bases, Arrhenius, Bronsted-Lowry, and Lewis acids and bases, conjugate acid-base pairs, strengths of acids and bases, ionization of water, Kw, [H3O+], [OH-], pH, pOH calculations. Format: mc
I will be able to use the Ka and/or Kb constant to find the [H3O+], [OH-], pH, pOH. I will be able to compare the Keq constants to determine which acid or base is stronger.
