About

Serious Solids

This educational game challenges players to identify the correct combinations of cations and anions to form solid precipitates. It's designed to help users learn to predict the products of common precipitation reactions through interactive experimentation.

Highlights
  • Predict precipitation reactions
  • Combine cations and anions
  • Form solid precipitates
  • Experiment with ion symbols
  • Earn points by swiping spectator ions

Read full description

The goal of the game is to select the correct ratios of cations (+) and anions (-) that combine to form solid precipitates at 0.1M ion concentrations, neutral pH, and 25 degrees C. Experiment with the interface by clicking the ion symbols multiple times. When the name and formula looks good to you, submit your solid by clicking the button at the bottom of the screen. Swipe spectator ions away from the screen to remove them and to earn extra game points. Good luck! We sincerely hope this game helps you learn how to predict the product of common precipitation reactions. This app was created and developed at Tennessee Tech University by instructor Janet Coonce, student Evgeny Vasilyev, and student Rodney Mitchell, in collaboration with TTU's iCube.

  • Interactive chemical simulations
  • Educational chemistry practice
Features
Read full description

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.
