Post-Lab Questions
Please provide solutions and explanations thank you!
Table 1: 10 mL Undiluted (1.0-2.0%) IKI and 5 mL 3% H2O2 mL water displaced Time...
Reaction 1 (10 mL undiluted 1.0% IKI and 5 mL undiluted 3% H2O2) Reaction 2 (10 mL diluted 0.5% IKI and 5 ml undiluted 3% H2O2) Reaction 3 (10 mL undiluted 1.0% IKI and 5 mL diluted 2.25% H2O2) 13. Answer the following. ( a) How many moles of H2O2 are present in Reactions 1 and 2? Show your work (include units). Hint: The initial H2O2 solution is 3% m/v (mass/volume) hydrogen peroxide in water. That means that 3 g...
PLease help!! Reaction 1 (10 mL undiluted 1.0% IKI and 5 mL undiluted 3% H2O2) Reaction 2 (10 mL diluted 0.5% IKI and 5 ml undiluted 3% H2O2) Reaction 3 (10 mL undiluted 1.0% IKI and 5 mL diluted 2.25% H2O2) How many moles of I3K are present in Reactions 1 and 3? Show your work (include units). Hint: The initial I3K solution is 1% m/v (mass/volume) potassium triiodide in water. That means that 3 g H2O2 are present in...
Trial 1 : 10 mL 1% I3K and 5 mL 3% H2O2 Trial 2: 10 mL .05% I3K and 5 mL 3% H2O2 trial 3: 10 mL 1% I3K and 5 mL 2.25% H2O2 1. (a) How many moles of H2O2 are present in rxn 1 and 2? (b) what is the total volume? 22mL of water used 2. How many moles of I3K are present in rxn 1 and 3?
