1. What we will do What we will learn 10N 26 Mahuru 2017
Quick quiz and preliminaries
How to start well
Revisit the chemical formulae and names of the three main acids used in school labs
What they are and how to write them (both ways)
Revisit the results for an acid & a metal
reacted – (many of them) to see the pattern, starting with the one we did in the lab
How to find a pattern and then use it to make the memory work smaller
Examine solubility, insolubility, solutions
and precipitates
Why some “mixes” make “solid snow”

9. Incompatible Ions.
There are times when we mix two ionic solutions together and this causes two ions that were not together to become mixed. For some combinations of ions, these become insoluble and form solids that settle out of solution. These settled solids are called precipitates (because they “fall out” like rain and snow “fall out”)
