Strong and weak acids and bases
Today we finished the PowerPoint on the last blog post and we discussed ka chart in our data booklets are organized- see notes below.

Acids and bases begin!!
During the first block today was the solubility unit exam.
Block 2 we started unit 4 - the acids and bases unit!
The link below will guide you to the introduction powerpoint for this unit

pollution precipitations
Today's notes on pollution precipitation
http://db.tt/icSjDRAL
IMPORTANT!! -- The solubility unit exam will be on WEDNESDAY, APRIL 18TH -- NOT TUESDAY. There is a grad assembly on Tuesday afternoon during block 3 so I had to move the exam!! I know this will make many of you happy.
Monday we will finish the unit -- please work on the solubility titration problems for Monday's class.

The solubility product and precipitates forming
Today we went over these solubility product notes and discussed whether precipitates will form or not.
Quiz on ksp on Wednesday !!
Solubility lab on wednesday!! Read through lab handout 12C below. Important note in the lab is to watch for ratios of ions!! Not all are 1:1!

Dissociation, net ionic & Qualitative analysis
Dissociation reaction practice and net ionic equations due tomorrow - evens only. See worksheet below.
Today we looked at qualitative analysis as a means to identify precipitates in reactions. We will do a lab on this tomorrow.
This lab will be a group lab -- one lab report submitted per group.

Titration races
We discussed ionic and net ionic solutions. See notes below.
Yesterday's class was a review of grade 11 titration exercises. Groups were in contest to see who could perform the most accurate titration based on the colour of the titrate
And the winner was:
