TA cannot find the magnesium strips, they should check the cart, the hood, and the box containing the other items needed for the demonstration.</span></p>

<p class="MsoNormal"><span style="font-family:"Buckeye Sans 2";color:#212121">Solid reagents will be handed out from the lab support windows. These are provided in class sets and should be picked up by the TA before lab starts. Do not give out partial sets
at the start of lab. We’ll be using the vacuum ports for this experiment; the TAs do not need to do anything with the vacuum pump. We will also be using the ovens; they open by pulling the bottom of the handle up towards the ceiling- no rotating required.
We strongly encourage TAs and students to keep the oven doors closed as much as possible. This helps prevent significant heat loss. When doing lab readiness checks, please verify that a box of P5 filter paper is present on the reagent cart. If not, grab one
from the window.</span></p>

<p class="MsoNormal"><span style="font-family:"Buckeye Sans 2";color:#212121">Be prepared to direct students to the window cart for burets, pipets, pipet pumps, and blue stoppers. Please refill the window cart when things start to get low- this goes for all
items on the window cart, not just the items being used for LLT. The 0.44 M NaOH carboy should be kept on the special carboy spill tray. Blue square carboys of 0.44 M NaOH should be swapped out during the lab readiness checks by those completing them. When
swapping out the blue carboys, check the fill level of the spill tray. Let us know if it’s more than half full. Partially filled bottles of lemon and lime juice should be placed in the fridge. We will periodically combine these. When doing a gather, please
check the fridge first for full bottles of lemon and lime juice. If you need more than what is available in the fridge, please grab new bottles from aisle 28.
<i>No partial bottles of lemon or lime juice should be left in aisle 28.</i></span></p>

salt for their ice baths. Keep a close eye on the 25-mL test tubes. If they need refilled, more are available behind the marker boards.</span></p>

in the window. Fill out a broken equipment sticker with as much detail as possible, and place it on the returned unit. One of the prep lab staff members will look at the “broken” kit. The students will be sanding the oxidation layer off the electrodes with
emery paper/cloth. This should be done on the provided cardstock; the card stock should be placed on the provided black plastic tray. The whole sanding procedure should be done under a snorkel. Each room has been provided with 7 trays since they only have
7 snorkels. <i><u>Students should not be sanding directly on the lab bench.</u></i></span></p>
