Bacterial ID Virtual Lab vs CloudLabs Ions Equilibrium

Learn about the science and techniques used to identify different types of bacteria based on their DNA sequences. Not long ago, DNA sequencing was a time-consuming, tedious process. With readily available commercial equipment and kits, it is now routine. The techniques used in this lab are applicable in a wide variety of settings, including scientific research and forensic labs. This app is geared for high school biology students and anyone interested in the biological sciences. The Bacterial ID Virtual Lab was first released in 2000 as a browser-based interactive lab. Since its inception, it and the other HHMI Virtual Labs have won several awards, including the Pirelli INTERNETional Award's top prize in 2002. The Howard Hughes Medical Institute (HHMI) is a nonprofit medical research organization that ranks as one of the nation’s largest philanthropies. HHMI plays a powerful role in advancing biomedical research and science education. HHMI brings the latest biomedical research into the classroom with the award-winning BioInteractive website and the Holiday Lectures on Science. BioInteractive features free resources for science education, including animations, videos, interactive features, and classroom materials. The Holiday Lectures on Science feature world-class scientists who bring their leading-edge research to the classroom.

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.
