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

2. The color and appearance (cubic/granular crystals) of the target substance conform to the description 'white, solid, cubic or granular crystals'.

3. The substance is appropriately contained in the beaker with a suitable quantity.

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 has a high melting point above 800°C. 2. Its aqueous solution conducts electricity. 3. It is highly soluble in water.>, please select the substance it most likely is from the following options:
Options:
A. Sodium Chloride (NaCl)
B. Calcium Carbonate (CaCO₃)
C. Sulfur (S)
D. Ethanol (C₂H₅OH)
E. None of the above
output: answer: A

turn: 3
modality: image
input: We will subsequently refer to the substance you identified earlier as the 'target substance'. The target substance can undergo <a precipitation reaction when its aqueous solution is mixed with a silver nitrate (AgNO₃) solution>. 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 experimental instruments are correct and match the precipitation reaction between sodium chloride and silver nitrate.

The target substance (sodium chloride) is generated in the correct form (a clear, colorless solution in a beaker), with its color and state conforming to its characteristics. The background should be a simple laboratory bench scene, consistent with the background in the Turn 1 output image.

3. The reactant (silver nitrate solution) is correctly depicted in the image with its color (colorless), state (solution), and location.

4. The reaction phenomenon conforms to 'the formation of a white, curdy precipitate'.

5. The image background is a laboratory bench.

modality: text
input: If, in the above normal reaction, the experimental procedure is incorrectly altered by <using concentrated sulfuric acid (H₂SO₄) instead of silver nitrate solution to test for chloride ions>, the most likely accident to occur is:
Options:
A. Violent reaction producing toxic hydrogen chloride gas
B. Formation of a harmless white precipitate
C. Spontaneous combustion of the mixture
D. Explosion due to rapid pressure build-up
E. None of the above
output: answer: A

turn: 5
modality: text
input: Regarding the laboratory accident described in the previous question, the most correct course of action is:
Options:
A. Immediately evacuate the area, ensure ventilation, and alert others to the toxic gas release.
B. Add water to the mixture to dilute the acid.
C. Attempt to neutralize the acid with a sodium hydroxide solution.
D. Cover the reaction vessel with a wet cloth to contain the gas.
E. None of the above
output: answer: A
