Exams are looming. Try last year’s paper tonight. Either print out and do or use paper to answer directly.
The end of Unit test for this topic will be on Friday. The basic knowledge you need for this part of the course can be found in the videos
The notes
The Zn/Cu electrochemical cell
Go into the holidays knowing that you can do this stuff.
Tackle the following revision questions.
Head up homework with the date. Copy the table below into your book. Imagine mixing a solution from the left hand column with a solution from the top row. If a precipitate forms when the solutions are mixed write the name of the precipitate on the grid. If no precipitate results write “no precipitate” on the grid.
Use the solubility rules from your book or from the previous post.
The first example is done for you:
mixing copper nitrate and sodium hydroxide solutions.
step 1 write the word equation and switch the names around
copper nitrate + sodium hydroxide ——-> copper hydroxide + sodium nitrate.
Step 2 are any of the products insoluble
All hydroxides apart from sodium and potassium are water insoluble. Copper hydroxide is insoluble and a precipitate is formed.
write on the grid in the first space copper hydroxide precipitates.
