Name Date Period Single Replacement Reactions Introduction: This Lab teaches the concepts of basic single replacement reactions in an inorganic solution system. The primary concept for this lab is the interaction of cations and anions in aqueous solution, using the general formula AX +B ---> BX + A, as determined by the rules of solubility and activity level of the Ionic compounds (AX) + metal cations (B) involved. The new combination of cations and anions in a chemical reaction yield products that may be a precipitate or gas. Look for a color change in the aqueous solution or the formation of a precipitate or gas. The Activity Series of the metals is an invaluable aid to predicting the products of replacement reactions. Pre-laboratory: Read the relevant pages of your textbook and notes. (single replacement reactions) Then answer the questions that follow. 1. What is a single replacement reaction? Give an algebraic example of one. 2. Define aqueous ions. 3. What evidence indicates that a single replacement reaction has occurred between the aqueous ionic compound and the metal? 4. List the metals found in the activity series from most reactive to least reactive Create a data table: 1. 2. 3. 4. For all reactions label the columns and rows by symbols Six by ten table Lab results label NR = no reaction, or R = reaction Unknown metal X for the second day of lab Single Replacement Reactions Activity series of Metals Metal Lithium Potassium Barium Strontium Calcium Sodium Magnesium Aluminum Manganese Zinc Chromium Iron Cadmium Cobalt Nickel Tin Lead (Hydrogen) Copper Mercury Silver Platinum Gold Metal Ion Li+ K+ Ba+ Sr2+ Ca2+ Na+ Mg2+ Al3+ Mn2+ Zn2+ Cr2+, Cr3+ Fe2+, Fe3+ Cd Co2+, Co3+ Ni2+, Ni3+ Sn2+, 4+ Pb2+ H+ Cu2+ Hg2+ Ag+ Pt2+ Au+, Au3+ Reactivity Most Reactive Least Reactive Single Replacement Reaction Predictions 1.
