High School Chemistry Experiment Infographic
Seven-section chemistry experiment infographic: I. Experimental Principles — Chemical equations for bromobenzene preparation via substitution reaction and verification (hydrolysis to phenol, FeCl3 color test). II. Experimental Apparatus — Realistic setup with round-bottom flask, thermometer, separating funnel, condenser, receiving flask. III. Experimental Steps — Six numbered illustrated steps from adding benzene to washing with Na2CO3. IV. Substitution Reaction Verification — Five numbered steps showing hydrolysis, acidification, and purple color reaction. V. Purification of Bromobenzene — Six numbered steps from crude product through filtration and distillation. VI. Safety Precautions — Five warning items with yellow triangles covering toxic bromine, corrosive FeBr3, temperature control. VII. Results & Conclusions — Three checkmark items confirming pure bromobenzene preparation and reaction verification.
