Cation and Anion Report

Name: Melody Wong N8426066 Cation and Anion Reaction 1. Objectives Educational Aims * To learn how to banding up a practical experiment * To comp atomic summate 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 unitary and only(a) set of chemical substances to another. Chemical reactions occur whenever bonds are constrain or broken between molecules. Chemical reactions can be classified into a few categories. In this experiment, we are kindling to observe trope replacement reaction. In a double replacement reaction, parts of deuce compounds switch places to form cardinal new compounds, This is when the anions and cations of two different molecules switch places, forming two fly 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 manifold with a result of potassium chromate, K2CrO4. A yellow fall down will form. This precipitate must be a conclave of the K + or Pb 2+ cation and the CrO4 2- or NO3 2- anion. Since most(prenominal) 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 flask * Buchner fun! nel * Stirring rod * mensuration cylinder * prove tube * Electronic balance Material: * 1.0 M kibibyte chromate solution * 1.0 M Lead (II) nitrate solution 3. mental process pervert 1 50mL of 1.0 M Potassium Chromate solution is added in a 100 mL beaker. whole tone 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 affluent essay, bless it on our website: BestEssayCheap.com
