turn: 1
modality: image
input: Please generate a concise chemical laboratory bench scene: A substance is contained in a <correct and appropriate laboratory container type>. The substance must exhibit the following observable characteristics: <color + physical state (solid/liquid/gas) + form (powder/lump/crystal/solution, etc.) + optional luster/transparency; the name, chemical formula, or element symbols of the substance are prohibited>. The background should be a <laboratory environment: bench surface, outlines of basic equipment, avoid clutter and text labels>.
output: evaluation_points: 1. The container generated in the image is correct and is indeed a <brown glass reagent bottle with a ground glass stopper>.

2. The color and appearance (powder/crystal/lump/solution, etc.) of the target substance conform to '<dark purple-black, solid, metallic luster, crystalline>'. The crystals should be clearly visible.

3. The substance is correctly contained in the bottle, with an appropriate amount filling part of the bottle's volume.

4. The background is a simple laboratory bench scene.

turn: 2

input: Based on the appearance of the substance in the input image, and given that this substance is known to have the following properties: 1) It sublimes readily at room temperature, producing a violet vapor. 2) It is only slightly soluble in water but dissolves well in organic solvents like ethanol or carbon tetrachloride, forming colored solutions. 3) It reacts with certain metals, such as aluminum, in the presence of a catalyst like water to form salts.

Which of the following substances is it most likely to be?

Options:
A. Potassium permanganate crystals (KMnO4)
B. Sulfur powder (S)
C. Iodine crystals (I2)
D. Copper(II) sulfate pentahydrate (CuSO4·5H2O)
E. None of the above
output: answer: C

turn: 3
modality: image
input: We will now refer to the substance you identified in the previous question as the 'target substance'. The target substance can undergo the following reaction: <Describe the reaction system and key conditions in one sentence, e.g., 'reacts with dilute hydrochloric acid to release gas', 'decomposes upon heating to produce gas', 'forms a precipitate upon reaction with a certain solution'; the name or chemical formula of the target substance is prohibited>. Please generate the state of the experiment on the bench during this normal reaction (the experimental apparatus, the state of the substances, and the reaction phenomena should all be reasonable and self-consistent).
output: evaluation_points: 1. The selection, connection, and use of the experimental apparatus are correct and match the <reaction of iodine with aluminum>.

2. The target substance is generated in the correct form (dark purple-black crystals) at the correct location in the image, with its color and state conforming to the characteristics of '<iodine crystals>'.

The target substance is generated in the correct form (dark purple-black crystals) at the correct location in the image, with its color and state conforming to the characteristics of 'dark purple-black, solid, metallic luster, crystalline' as described in turn 1.

The <aluminum powder or foil> is correctly depicted in the image with its correct color (silvery-gray), state (solid powder or foil), and location (mixed with or in contact with the target substance).

The reaction phenomenon conforms to '<vigorous reaction producing heat and purple vapor, with the formation of a white to grayish solid product visible>'. The vapor should be illustrated.

input: If, in the normal reaction described above, the experimental setup is incorrectly modified by <describing 'only the one wrong change' in one sentence, e.g., 'the delivery tube is not equipped to prevent suck-back', 'water is poured into concentrated acid', 'heating a flammable solvent near an open flame', 'heating in a sealed container leading to increased pressure'; the name or chemical formula of the substance is prohibited>, what is the most likely accident to occur?

Options:
A. Violent ejection of hot contents due to rapid pressure buildup.
B. Toxic gas leakage leading to inhalation exposure.
C. Fire or explosion due to ignition of flammable vapors.
D. Corrosive liquid splash causing chemical burns.
E. None of the above
output: answer: B

turn: 5
modality: text
input: Regarding the laboratory accident described in the previous question, what is the most correct course of action?

Options:
A. Immediately evacuate the area, alert others, and ensure the laboratory ventilation system is operating at maximum capacity. Do not attempt to handle the source until the area is clear of vapor.
B. Use a fire extinguisher (CO2 or dry chemical) to suppress any visible reaction and then approach to clean up.
C. Pour water over the reaction vessel to cool it down and dilute any spilled chemicals.
D. Use a wet cloth to cover the reaction vessel to smother any vapor production.
E. None of the above
output: answer: A
