Information About Chemistry Reaction
What type of reaction is our chemical equation?
Acid + Base → Salt + Water (Neutralization Double Replacement)
How do you do a point yield calculation?
Actual yield: the value you got in the lab Theoretical yield: the value you should have gotten based on calculations The HIGHER the percentage, the better!
What is our chemical equation?
H2SO4 (aq) + Ca(OH)2 (s) → CaSO4(s) + 2H(OH)(l)
Procedure?
Solid Calcium Hydroxide: 1.088 g Dissolve Calcium Hydroxide=aqueous solution Dissolve in a beaker of ice. Exothermic=dangerous Then put into an Erlenmeyer flask. Aqueous Sulfuric Acid: 14.069 ml, Combine and mix; produces water and Calcium Sulfate. Pour on filter paper using a funnel. Let water drip into a beaker. Heat lamp or let dry! 2.00 g of Calcium Sulfate Precipitate should be produced - check using weight and initial filter paper weight
What are the names of the chemicals within our chemical equation?
Sulfuric Acid + Calcium Hydroxide → Calcium Sulfate + Water
