CHEM 110 Cuyamaca College Limiting Reagent of Solutions Lab Report


I’m studying and demand succor after a while a Chemistry inquiry to succor me attain.

  • Part A
    • Experimental postulates board and fitted results
    • Limiting reagent
    • Balanced equation after a while states
  • Part B
    • Record observations
    • Fill out a delineation of the board on page 37 of the lab manual (delineation in excel).
    • Limiting reagent
    • Balanced equation after a while states
  • Discussion Questions
  • Calculation
  • Moles CaCl2, Na2CO3, limiting reagent plant through caution, speculative moles CaCo3, Objective heap of CaCo3, percent render CaCO3.
    • Sig figs. Beaker versus graduated cylinder for reagents. Avoid rounding hallucination.
    • Percent render=actual*100/theoretical
    • Consistent parts
      • What factors can subscribe to a low percent render?
      • What factor subscribe to a tall percent render?
    • Units are considerable for part segregation.
    • Finding the limiting reagent:
    • Moles reagent*(moles work/moles reagent)=moles work
    • Reagent that leads to the lowest moles work= limiting reagent
    • Finding speculative render (g):
    • Moles work naturalized on limiting reagent 🡪 grams work
    • Finding objective render (g):
    • (Mass of wait glass+filterpaper+precipitate)- (heap of wait glass +percolate tractate)
    • Pay care to molarity when determining the limiting reagent
