Do not proceed to schedule a custom demo unless you have already conferred with the lecture demonstrator about it.Lead(II) nitrate is an inorganic compound with the chemical formula Pb( NO 3) 2. The custom demos section of the website is used by UO chemistry instructors to schedule demonstrations that are not listed in the database.

"Do not do demos unless you are an experienced chemist!" Please read the following disclaimer carefullyīy continuing to view the descriptions of the demonstrations you have agreed to the following disclaimer. explain what causes the aqueous copper(II) sulfate solution to be blue and why the blue color fades as the reaction proceeds explain why zinc is a more active metal when compared to copperĤ. identify what is being oxidized and wht is being reducedģ. write the oxidation half-reaction and the reduction half-reactionĢ. Purdue University's chemistry demonstration web site has an excellent "movie" of this lecture demonstrationĪfter viewing the demonstration and the computer animation at the particle level (molecular scenes), students should be able toġ. A new HTML5 based computer simulation of this activity is planned to be developed. This is an OLD FLASH-based computer simulation developed by Tom Greenbowe and his chemistry education research group. ©2010 Greenbowe Chemistry Education Instructional Resources. Based on observations, write the the oxidation-reduction half-reactions. Option to view a computer animation at the particle level of the interaction of the M 2 +ion with the metal electrode. Build an activity series of meals based upon observations of whether or not a metal reacts with a M 2 +aqueous solution. Select various metals to test in aqueous M 2 + solutions. A set Power Point slides attempting to infuse some active learning in the presentation of this demonstration is posted on the menu to the right.Īctivity Series of Metals Computer Simulation The effectiveness of the demonstration is increased when 1) students are led through a guided-inquiry instructional sequence, 2) students view a computer animation representing what occurs at the atom level: the oxidation of zinc and the reduction of Cu 2 + ions, and 3) students work the activity sheet that accompanies the demonstration and computer simulation. Use a series of well crafted questions, visualizations and a POGIL-ish tutorial to guide your students to understanding under what conditions single displacement reactions will occur. Please consider not lecturing to your students. This demo can also be used when discussing single-replacement reactions, redox reactions, or electronegativity. This is a great demo to present at the beginning of a unit on electrochemistry because it can be followed later in the unit by the zinc/copper cell demo.
