Assignment:
Salicylic acid, used in the manufacture of aspirin, contains only the elements carbon, hydrogen and oxygen. Each molecule of the acid contains only one acidic hydrogen. When 1.00g of salicylic acid undergoes complete combustion, 2.23g CO2 and 0.39 g of H2O are formed. When 1.00g of salicylic acid is titrated with 0.100M NaOH, 72.4mL of base is needed for a complete reaction.
a. What is the empirical formula for salicylic acid?
b. What is the molecular formula for salicylic acid?
c. Write a balanced chemical equation for the neutralization of salicylic acid by sodium hydroxide.
Provide complete and step by step solution for the question and show calculations and use formulas.
