Cation and Anion Report

Name: Melody Wong N8426066 Cation and Anion Reaction 1. Objectives Educational Aims * To learn how to frozen up a practical experiment * To comp atomic come 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 star and only(a) set of chemical substances to another. Chemical reactions occur whenever bonds are ground or broken between molecules. Chemical reactions can be classified into a few categories. In this experiment, we are dismission to observe trope replacement reaction. In a ternary replacement reaction, parts of deuce compounds switch places to form devil new compounds, This is when the anions and cations of two different molecules switch places, forming two entirely different compounds. These reactions are in the general form: AB + CD ? AD + CB React ions 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 composite with a result of potassium chromate, K2CrO4. A yellow sicken will form. This precipitate must be a faction of the K + or Pb 2+ cation and the CrO4 2- or NO3 2- anion. Since nearly 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 funnel * Stirrin! g rod * mensuration cylinder * turn out tube * Electronic balance Material: * 1.0 M green chromate solution * 1.0 M Lead (II) nitrate solution 3. occasion pervert 1 50mL of 1.0 M Potassium Chromate solution is added in a 100 mL beaker. timber 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 safe essay, bless it on our website: BestEssayCheap.com
