360Science™: Identify Unknowns Through Stoichiometry
Concepts: Stoichiometry, ideal gas law, acid–base titrations, limiting reagents
Outcomes: Students should become comfortable with stoichiometry calculations and how that information can be useful in determining the unknown identities of different compounds. Both techniques used in this lab help students understand the importance in being precise and accurate when making measurements. When using the mass loss of carbon dioxide to determine the identity, the outcome is heavily dependent on careful measurements. The mass of CO2 lost is small and can be obscured by poor measurements. With titrations there needs to be care in not overshooting the endpoint, as that can lead to inaccurate calculations that could in turn affect the identification of the unknown metal carbonate.

What is Flinn 360Science™?
We’re introducing a whole new way to teach experiential science! We’ve taken a hard look at science study from all perspectives and, thanks to the feedback of thousands of teachers nationwide, we’ve created a way to make it easier to provide personalized instruction while delivering the kind of lab experiences your students truly need.
Our new and comprehensive learning solutions are designed to bring science to life by giving you all the tools you need to incorporate more (and effective) hands-on learning in your classroom or lab. 360Science allows you to provide your students with the support they need to make real-world connections to key scientific principles and help make those abstract concepts concrete.
Every 360Science lab solves the most common challenges educators face in bringing more hands-on science to their students—from not having enough time to matching the right level of challenge for students’ abilities to providing appropriate background content, safety techniques, assessments and more.
Enable student-driven, blended learning through a unique combination of leveled lab instructions supporting prescriptive, guided- and open-inquiry lab exercises (see PDF resource for specific details) with robust digital content, such as videos and carefully curated Open Educational Resources (OER)—along with virtual reality and simulation exercises. From editable, digital instructions to assessments and alignment with Next Generation Science Standards (NGSS), we have everything you need to improve mastery, remove the intimidation factor and foster your students’ natural curiosity.
