VSEPR Chemistry Invaders vs CloudLabs Ions Equilibrium

VSEPR invaders in an arcade-style shooter app that helps students learn the various molecular geometries as a result of electron repulsion. First, users learn various different VSEPR configurations. These include: Linear, Trigonal Planar, Tetrahedral, Trigonal Bipyramidal, and Octahedral. Next, the user starts the game and has a certain amount of time to shoot as many geometry models as possible. Each ten-second segment of the game selects a certain molecular geometry and the student must target these models in order to score five points. If the user shoots the incorrect model during the ten second period, they lose 1 point. Once, the timer has reached ninety seconds, the game stops and the user's score is reported. This app provides a fun and interactive experience to help learn molecular geometry in an innovative and new manner. The free version of the app features games that last 1 to 2 minutes and the In-App purchase provides extended game length from 3 to 8 minutes.

In this laboratory you will have a bottle with deionized water, a bottle with iron (II) nitrate, a bottle with potassium thiocyanate, a bottle with sodium hydroxide, two test tubes, a rack and four pipettors. The objective of the practice is to determine the amount of sodium hydroxide that can reduce the initially produced concentration of iron nitrate, potassium thiocyanate and water, in addition to finding the equilibrium constant of the reaction.
