Do you need a quicker lab for your students to observe LeChatelier's Principle? I've written one up that you can do in under 45 minutes! This lab consists of 5 stations around the room. Students rotate through each station, perform a mini experiment, and answer questions on a handout along the way.
This product includes teacher instructions, a student lab sheet (with procedures) and an answer key. These items are in WORD format, so they're fully editable.
*You do need the following materials:
1-2 Petri dishes, small amounts of dilute KSCN solution, solid KSCN, dilute Fe(NO3)3 solution, solid KNO3, solid NaH2PO4, bromthymol blue, dilute HCl, dilute NaOH, dilute CuSO4 solution, concentration ammonia (in fume hood), dilute NH3, carbonated water (soda water), bromcresol green indicator, dropper bottles, a large syringe without the needle, and basic lab equipment.
