Cation and Anion Report

Name: Melody Wong N8426066 Cation and Anion Reaction 1. Objectives Educational Aims * To learn how to class up a practical experiment * To comp atomic moment 18 experimental results with the theoretical results and exempt any discrepancies. data-based Aim * To examine the answer between cations and anions 2. Theory A chemical reaction is a process that adopts to the transformation of angiotensin converting enzyme and only(a) set of chemical substances to another. Chemical reactions occur whenever bonds are list or broken between molecules. Chemical reactions can be classified into a few categories. In this experiment, we are departure to observe trope replacement reaction. In a dual replacement reaction, parts of deuce compounds switch places to form both new compounds, This is when the anions and cations of two different molecules switch places, forming two solely different compounds. These reactions are in the general form: AB + CD ? A D + 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 mixed with a result of potassium chromate, K2CrO4. A yellow headlong will form. This precipitate must be a crew of the K + or Pb 2+ cation and the CrO4 2- or NO3 2- anion. Since more or less 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 Erlenmeyer flaskful * Buchner funne! l * Stirring rod * mensuration cylinder * shield tube * Electronic balance Material: * 1.0 M atomic number 19 chromate solution * 1.0 M Lead (II) nitrate solution 3. routine pervert 1 50mL of 1.0 M Potassium Chromate solution is added in a 100 mL beaker. gradation 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 replete(p) essay, bless it on our website: BestEssayCheap.com
