turn: 1
modality: image
input: Please generate a concise chemical laboratory bench scene: A substance is contained in a <watch glass>. The substance must have the following observable appearance: <white, solid, crystalline, opaque>. The background should be a <laboratory environment: bench surface, basic equipment outlines only, avoid clutter and text labels>.
output: evaluation_points: 1. The generated container is correct, specifically a watch glass.

2. The target substance's color and appearance (white, solid, crystalline) conform to the described morphological features.

3. The substance is appropriately contained on the watch glass in a suitable quantity.

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 has a high melting point above 800°C. 2. Its aqueous solution conducts electricity. 3. It is highly soluble in water.>, which of the following substances is it most likely to be?

Options:
A. Copper(II) sulfate pentahydrate (blue crystals)
B. Sodium chloride (white crystalline solid)
C. Sulfur powder (yellow powder)
D. Calcium carbonate (white powder)
E. None of the above
output: answer: B

turn: 3
modality: text
input: The substance you identified in the previous context is commonly used as the main active ingredient or core functional component in which of the following household products?

Options:
A. Dishwashing liquid (core component: surfactants for grease removal)
B. Table salt (core component: seasoning and preservative)
C. Bleach (core component: sodium hypochlorite for disinfection and whitening)
D. Baking soda (core component: sodium bicarbonate for leavening and cleaning)
E. None of the above
output: answer: B

turn: 4
modality: image
input: Please generate a real-life scene: using the household product corresponding to the correct option from the previous question (table salt) to treat <a piece of raw meat (e.g., a chicken breast)>. The scene should naturally show an observable change "before and after treatment" or "during the treatment process" that can be directly seen.
output: evaluation_points: 1. The generated scene conforms to the described 'real-life kitchen scene', with a reasonable setting and target object (raw meat).

2. The scene correctly features table salt, and its application method (sprinkling/rubbing onto the meat surface) conforms to common usage for curing/preserving.

There is a clear observable change during the process: visible salt crystals adhering to the moist surface of the meat, and potentially a slight darkening or moisture extraction on the meat's surface over time (simulating the curing effect). The salt crystals should appear as a white, solid, crystalline substance, consistent with the appearance of the substance in the watch glass from Turn 1.

turn: 5
modality: text
input: Based on the life phenomenon shown in the input image (using salt on meat) and your previous judgment, which of the following chemical reaction equations describes the core process occurring?

Options:
A. NaCl(s) → Na⁺(aq) + Cl⁻(aq) (Dissolution in meat moisture, creating a hypertonic environment)
B. NaCl + H₂O → NaOH + HCl (Requires electrolysis)
C. 2NaCl + 2H₂O → Cl₂(g) + H₂(g) + 2NaOH(aq) (Electrolysis reaction)
D. NaCl + AgNO₃ → AgCl(s) + NaNO₃ (Precipitation reaction)
E. None of the above
output: answer: A
