Domain: Chemistry / lab_accident

turn: 1
modality: image
input: Generate a concise chemical laboratory bench scene: A substance is contained in a crucible. The substance must have the following observable appearance: black, solid, fine powder, opaque. The background should be a laboratory environment: a bench with basic equipment outlines, avoiding clutter and text labels.
output: evaluation_points: 1. The generated container is correct and is indeed a crucible.

2. The color and appearance (fine powder) of the target substance conform to 'black, solid, fine powder'.

3. The substance is appropriately contained in the crucible, with a suitable amount.

4. The background is a simple laboratory bench scene.

turn: 2
modality: text
input: Based on the appearance of the substance in the input image, and given that this substance has the following properties: (1) It is insoluble in water. (2) It reacts with dilute sulfuric acid to form a blue solution. (3) It is thermally stable and does not decompose upon heating in air. Which of the following substances is it most likely to be?

Options:
A. Iron(III) Oxide (Fe2O3, reddish-brown powder)
B. Copper(II) Oxide (CuO, black powder)
C. Sodium Chloride (NaCl, white crystalline solid)
D. Calcium Carbonate (CaCO3, white powder)
E. None of the above
output: answer: B

turn: 3
modality: image
input: We will subsequently refer to the substance you identified in the previous text as the 'target substance'. The target substance can react with dilute sulfuric acid to form a blue solution. Please generate the state of the laboratory bench during this normal reaction (experimental apparatus, state of substances, and reaction phenomena should all be reasonable and self-consistent).
output: evaluation_points: 1. The selection, connection, and use of experimental instruments are correct and match the reaction of the target substance with dilute sulfuric acid.

2. The target substance is generated in the correct form (black powder) at the correct position in the diagram, with color and state conforming to the characteristics of 'Copper(II) Oxide powder'.

3. The reactant, dilute sulfuric acid (a colorless liquid), is generated with the correct color, state, and location in the diagram.

4. The reaction phenomenon conforms to 'the black powder dissolves to form a clear blue solution'.

5. The image background is a laboratory bench.

turn: 4
modality: text
input: If, in the above normal reaction, the dilute sulfuric acid were mistakenly replaced with concentrated sulfuric acid, what is the most likely accident to occur?

Options:
A. Violent boiling and splattering of hot acid due to rapid, exothermic dissolution.
B. No reaction occurs; the black powder remains unchanged.
C. The solution turns green instead of blue.
D. A flammable gas is produced, creating a fire hazard.
E. None of the above
output: answer: A

turn: 5
modality: image
input: Please generate the scene of the experimental accident described in the previous question and show the correct way to handle this accident.
output: evaluation_points: 1. The diagram correctly shows the phenomenon and state after the accident occurs: splatters of hot, concentrated acid on the bench.

2. The diagram shows the correct accident handling method: a laboratory technician is carefully and slowly diluting the spilled concentrated acid with copious amounts of water, wearing appropriate PPE (gloves, goggles, lab coat).

The background and other irrelevant elements remain consistent with the laboratory bench scene generated in turn 1, with no significant changes.

The image is clearly modified from the reaction scene generated in turn 3, not a completely newly generated image.
