Solution Steps

Step 1: Identify the Reactant in Solid Form

To determine which reactant is a solid that is weighed out before the start of the synthesis reaction, we need to identify the physical state of each listed compound.

Step 2: Analyze Each Compound
  • Acetic anhydride: This is a liquid at room temperature.
  • Salicylic acid: This is a solid at room temperature.
  • Acetic acid: This is a liquid at room temperature.
  • Sulfuric acid: This is a liquid at room temperature.
  • Acetylsalicylic acid: This is a solid at room temperature.
Step 3: Determine the Correct Solid Reactant

Among the listed compounds, salicylic acid is a solid that is typically weighed out before the start of a synthesis reaction, such as in the synthesis of acetylsalicylic acid (aspirin).

Final Answer

\(\boxed{\text{salicylic acid}}\)
