  Lab: Using Qualitative Analysis to Identify Household Compounds Mark as Favorite (64 Favorites)

  In this lab, students will be introduced to common laboratory techniques, safety procedures, lab reagents, and terminology, all while identifying unknown household substances. Students will learn how to use qualitative analysis techniques as a systematic way to identify unknown materials. As part of this process, they will practice careful observation and documentation, as well as identifying relevant physical and chemical properties and changes, including solubility, color change, gas formation, and precipitation of solids.

  Lab: A Comparison of Two Chemical Reactions Mark as Favorite (47 Favorites)

  In this lab, students will perform two chemical reactions, one between acetic acid and sodium bicarbonate and the other between the citric acid and the sodium bicarbonate in an Alka-Seltzer tablet when dissolved in water. Both reactions will produce gas while reacting in a closed plastic sandwich bag, causing it to inflate. Students will observe the reactions and analyze the results in order to understand indicators of chemical changes, heat flow, and factors that affect reaction rates
