Want to refresh your memory on named chemical reactions before an exam or a group meeting? Get all the details with ReactionFlash(R) as a great way to learn named reactions, understand their mechanisms and view examples published in peer-reviewed literature. Designed and developed in consultation with Professor Dr. Erick M. Carreira of ETH Zürich, the app covers 1'266 named chemical reactions, by far the largest collection of Named Reactions. Professor Carreira has helped ensure that we have all the fundamental reactions that should be part of every chemist’s toolkit: from the best-known ones to the ones only Nobel Prize winners remember! The app is designed like a set of flash cards so it can be used as a learning tool as well as a reference. Each ‘card’ shows the reaction, its mechanism and examples from peer-reviewed, published literature. It also has a quiz mode that lets you test your knowledge. Linking into Reaxys enables you to find the most recent examples of each reaction, many with experimental details. Reaxys delivers experimental facts from the literature, enabling researchers to find the best synthetic routes and conditions.

Explore 150 chemicals in a virtual lab in the BEAKER app. Add in chemicals, heat it up, and shake your device to start reactions. Pour them out to clean it up. Or team up with your friends to pour chemicals between each other via AirMix™. Use virtual Match, Lid and Burner to assist your experiment. Or get the extra five tools - Blender, Cooler, Separator, Filter and Meter to do even more complex operations. Start (tap or hold on chemicals to add) - CaO + H2O - K + H2O (fire) - Na + H2O (fire) - Al + Br2 (fire) Ignite (swipe your finger and hold, like striking a match) - Ignite Mg, C, Al - Ignite H2 + O2 (explosion) Heat Up (swipe in from the lower right corner to turn on Burner) - Boil Water (H2O) - Heat Fe + HNO3 (color transformation) Shake (shake to accelerate reactions) - CuSO4 + H2O + Mg (color transformation) - AgNO3 + H2O + Cu (precipitation) - AgNO3 + H2O + NaCl (precipitation) AirMix* (nearby BEAKERs will pair automatically) - Pour Na into Cl2 (fire) - Pour CH3COOH into NaHCO3 + Blue (bubbles) - Pour NaCl + H2O into AgNO3 + H2O (precipitation) * AirMix requires an Internet connection and geolocation services.
