Looking Good Reaction Stoichiometry And Percent Yield Lab
Ø Prepare potassium aluminum sulfate by reacting aluminum with hydroxide and sulfuric acid.
Reaction stoichiometry and percent yield lab. What is the mole ratio of the reactants to one another and what is the mole ratio of Al metal to Cu Metal. Write the balanced equation for the reaction of aluminum with copperII sulfate solution2Als 3CuSO4aq -- Al2SO43aq 3Cus 2. To predict the amount of product generated from a double displacement reaction.
In the lab chemists usually produce less reactants than anticipated. Predict and calculate the theoretical maximum amount of product produced in a precipitation reaction using stoichiometry. Percent Yields Calculate the theoretical yield of NaCl for the reaction using stoichiometry.
The formula for percent yield is percent yield 100 x absolute value actual yield predicted yield. Explain differences between theoretical and actual yield in a controlled experiment. There may be other reactions involving the same reactants that compete with the expected reaction.
CHEM 1105 Experiment 7 1 EXPERIMENT 7 Reaction Stoichiometry and Percent Yield INTRODUCTION Stoichiometry calculations are about calculating the amounts of substances that react and form in a chemical reaction. Khan Academy Single Replacement Reaction u0026 Stoichiometry u0026 Percent Yield Experiment 4. Students were able to calculate the moles of CuSO4 Al and determine the limiting reactant.
Percent Yields Calculate the theoretical yield of NaCl for both reactions 73 and 74 via standard mass-to-mass stoichiometry. Give an example other than the ones listed in this experiment of redox and metathesis reactions. Perform a precipitation reaction and measure the precipitate to calculate percent yield.
This lab will take 2-3 days to complete and will act as your summative assessment for this unit. Single Replacement Reaction Stoichiometry Student Name Date Data Activity 1 Write the balanced equation for the reaction of aluminum with copper II sulfate solution 2. Chemistry questions and answers.
