Consider the balanced equation given in the Background.
If you don't add sulfuric acid in your Procedure, you will produce
very little product during the same amount of lab time. What is the
most likely role of the sulfuric acid that you added in the
Procedure?
a. Solvent
b. Catalyst
c. Reactant
d. Product

Write the balanced chemical equation for the reaction between sodium bicarbonate and sulfuric acid (products are sodium sulfate, carbon dioxide, and water). If you used 10 mL of 2.0 M H2SO4 and 2.50 g of NaHCO3 in a similar reaction to what you did in lab, which reactant is limiting? Show all calculations.

Mustrates treat all types of ilnesses. Background Aspirin is a prodrug of salicylic acid, the actual active drug. A compound related to salicylic acid, salicin, was first isolated from willow bark in the mid 1700's, but willow-bark extract was used by the andient Greeks as a treatment for pain and fever. Salicylic acid (and many related phenols) are very hard on your Ho stomach, but when esterified, as aspirin is, they are much better tolerated. Simple esters are...

Questions 1. Why is it necessary to write the balanced chemical equation for the reaction before completing any stoichiometry problems? The balanced equation makes it possible to Convert information about a reactant or product to quantitative data, per the Conservation of matter. 2.

Based on your percent yield, indicate a source of error...

QUESTIONS 1. What is the purpose of the sulfuric acid (yes, it's a catalyst, but why is it a catalyst? What is it doing that makes the reaction possible? Would the reaction just go slower without it, or would the reaction not go at all? Why?) 2. If isobutyl alcohol (2 methyl propanol) is used instead of tert butyl alcohol, a mixture of products is obtained. One the products is the same as the product obtained with the tert butyl...
