turn: 1
modality: image
input: Please generate a concise chemical laboratory bench scene: A substance is contained in a <beaker>. The substance must have the following observable appearance: <white solid powder, opaque, no visible crystals>. The background should be a <laboratory environment: bench surface with basic equipment outlines, avoid clutter and text labels>.
output: evaluation_points: 1. The container generated in the image is correct and is indeed a <beaker>.

2. The color and physical form (powder/crystalline/lump/solution, etc.) of the target substance conforms to '<white solid powder>'.

3. The substance is appropriately contained in the beaker (no special storage requirements needed here), and the quantity is suitable.

4. The background is a simple laboratory bench scene.

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 is soluble in water, and its aqueous solution is alkaline. 2. It decomposes upon heating to release carbon dioxide gas. 3. It reacts with acids to produce effervescence.>, please select from the following options the substance it most likely is:

A. Sodium Bicarbonate (NaHCO3)
B. Calcium Carbonate (CaCO3)
C. Sodium Carbonate (Na2CO3)
D. Sodium Chloride (NaCl)
E. None of the above
output: answer: C

turn: 3
modality: text
input: Based on the substance you identified in the previous context (we'll call it the 'target substance'), which of the following household products is it commonly used as the main active ingredient or core functional component?

A. Laundry Detergent (for water softening and stain removal)
B. Baking Soda (for leavening in baking)
C. Table Salt (for seasoning and food preservation)
D. Drain Cleaner (for clearing clogs via strong alkali action)
E. None of the above
output: answer: A

turn: 4
modality: image
input: Please generate a real-life scene: Using the household product corresponding to the correct option from the previous question (Laundry Detergent), treat <a white cotton T-shirt with a prominent, fresh red wine stain>. The scene should naturally show an observable change 'before/after treatment or during the treatment process'.
output: evaluation_points: 1. The scene depicted in the image conforms to the described '<household laundry scenario>', with a reasonable setting and target object (stained T-shirt).

The scene correctly features <laundry detergent> (the main active ingredient of which is Sodium Carbonate (Na2CO3), as identified from the previous context) and its usage (e.g., being applied to or dissolved near the stain) aligns with common practice.

3. There is a clear observable change during/before/after treatment: <The intensity and area of the red wine stain visibly diminish or the stain becomes lighter/fades>.

turn: 5
modality: text
input: Based on the household phenomenon shown in the input image and your previous judgments, determine which of the following chemical reaction equations describes the process occurring?

A. Na2CO3 + 2HCl → 2NaCl + H2O + CO2↑
B. CaCO3 + 2HCl → CaCl2 + H2O + CO2↑
C. Na2CO3 + H2O → NaOH + NaHCO3
D. NaHCO3 + CH3COOH → CH3COONa + H2O + CO2↑
E. None of the above
output: answer: A
