@VernierST In AP Chemistry we use the flat pH sensors and Spectrovis+ for many of our experiments. The Go direct temp and pressure sensors make studying boiling point depression under vacuum and cinch.
Last day of Chemists Celebrating Earth Week 😢 Oh wait, I can do that every day. #GetAChargeOutofChemistry. Zinc Electroplating a Penny. Student AP Chemistry One-Pager on Electrochemistry. #CCEW
It's a half-life sort of day. Thanks to Spectrum Techniques' @ORNL isotope generator and @VernierST 's radiation probe, you can watch several half-lives of Ba-137m in under 10 minutes. I can live with 4.3% error.
We have @VernierST platinum-cell conductivity probes, so I said come back in flex. He did! The data beautifully shows the consumption of our I- catalyst but then the regeneration of our I- catalyst. Chemistry- where the textbook comes to LIFE!
After discussing the kinetics of reaction mechanisms with catalysts and seeing a picture in the textbook (@pearson) of the decomposition of H2O2 catalyzed by NaBr, a student asked if we could measure the concentration of the ion catalyst.
