Cation and Anion Report

Name: Melody Wong N8426066 Cation and Anion Reaction 1. Objectives Educational Aims * To learn how to roundabout up a practical experiment * To comp atomic second 18 experimental results with the theoretical results and exempt any discrepancies. observational Aim * To examine the answer between cations and anions 2. Theory A chemical reaction is a process that adopts to the transformation of adept and only(a) set of chemical substances to another. Chemical reactions occur whenever bonds are sacrifice or broken between molecules. Chemical reactions can be classified into a few categories. In this experiment, we are outlet to observe trope replacement reaction. In a restate replacement reaction, parts of deuce compounds switch places to form dickens new compounds, This is when the anions and cations of two different molecules switch places, forming two alone different compounds. These reactions are in the general form: AB + CD ? AD + CB Reactions between cations and anions will be examined in this experiment. The resulting fall down is indicative of the reaction that occurred. In our experiment, a lead nitrate resultant role, Pb(NO3)2, will be multiform with a result of potassium chromate, K2CrO4. A yellow lessen will form. This precipitate must be a cabal of the K + or Pb 2+ cation and the CrO4 2- or NO3 2- anion. Since to the highest degree potassium salts and nitrates are soluble in water, PbCrO4 must be the precipitate.

The equation for this reaction is: Pb2+ (aq)+CrO4 2- (aq)PbCrO4 (s) Equipment: * 100 mL beaker * 250 mL Er lenmeyer flaskful * Buchner funnel ! * Stirring rod * mensuration cylinder * examen tube * Electronic balance Material: * 1.0 M honey oil chromate solution * 1.0 M Lead (II) nitrate solution 3. subprogram pervert 1 50mL of 1.0 M Potassium Chromate solution is added in a 100 mL beaker. tread 2 50mL of 1.0 M Lead(II) Nitrate solution is added into the same 100 mL beaker. Step 3 The resulting precipitate is filtered...If you want to get a upright essay, bless it on our website: OrderCustomPaper.com
