Experiment 6 Chemical Periodicity DATA TABLES: Please fill in and upload as a PDF where indicated Use the video to fill in the table below: Reactivity of Metals A. REACTIVITY WITHIN THE METALS Metal Observations when added to water Li movement, bubble production, fizzing slightly and dissolving and reacting with water Na vapors, loud sizzling sounds K It became very red, rapid movement, loud crackles, produced vapors immediately B. REACTIVITY WITHIN THE NONMETALS For this part, please watch the video and look at the pictures as well. Reactivity of Nonmetals: Halogen Replacements Cl₂ Br₂ I₂ Data for the table below Preliminary Observations Solution Color of initial halogen Cl₂ clear/milky Br₂ orange I₂ purple Use the pictures below to fill out the table: Br₂ + KCl Br₂ + KI Br₂ + KBr Cl₂ + KI Cl₂ + KBr I₂ + KCl I₂ + KI I₂ + KBr Test for halogen replacement reactions Reaction Initial Halogen Color of Final Halogen Final Halogen Reaction? (yes or no) Less reactive halogen More reactive halogen Br₂ + KCl Br₂ orange Br₂ no Br₂ Cl₂ Br₂ + KI Br₂ purple I₂ yes I₂ Br₂ Cl₂ + KBr Cl₂ orange Br₂ yes Br₂ Cl₂ Cl₂ + KI Cl₂ purple I₂ yes I₂ Cl₂ I₂ + KCl I₂ purple I₂ no I₂ Cl₂ I₂ + KBr I₂ purple I₂ no I₂ Br₂
