1. what is the chemical formula for Aspirin C9H8O4(s) reacting with water to form salicylic acid C7H6O3(s) and acetic acid C2H4O2(aq)?
The chemical equation is as follows:
C9H8O4 + HOH ==> C7H6O3 + CH3COOH
I can't draw the structures on this site but you can Google the subject and see the structural formulas as well as videos of the mechanism. I encourage you to do that.
To determine the chemical formula for Aspirin (C9H8O4) reacting with water to form salicylic acid (C7H6O3) and acetic acid (C2H4O2), we need to balance the chemical equation for this reaction.
The balanced chemical equation can be represented as follows:
C9H8O4 + H2O → C7H6O3 + C2H4O2
To balance the equation, we need to ensure that there is an equal number of atoms of each element on both sides.
Let's break down the number of atoms for each element on both sides of the equation:
On the left-hand side (reactants):
- Carbon (C): 9 atoms
- Hydrogen (H): 8 atoms
- Oxygen (O): 4 atoms
On the right-hand side (products):
- Carbon (C): 9 atoms (C7 + C2)
- Hydrogen (H): 8 atoms (H6 + H2)
- Oxygen (O): 5 atoms (O3 + O2)
To balance the equation, we can adjust the coefficients:
2C9H8O4 + 9H2O → 2C7H6O3 + 9C2H4O2
Now, both sides of the equation have balanced numbers of atoms for each element:
- Carbon (C): 18 atoms on both sides
- Hydrogen (H): 18 atoms on both sides
- Oxygen (O): 18 atoms on both sides
Therefore, the balanced chemical equation for the reaction of Aspirin with water to form salicylic acid and acetic acid is:
2C9H8O4 + 9H2O → 2C7H6O3 + 9C2H4O2
