turn: 1
modality: image
input: Please generate a concise chemical laboratory bench scene: A <correct and appropriate laboratory container type> contains a substance. This substance must exhibit the following observable appearance: <color + physical state (solid/liquid/gas) + form (powder/lump/crystal/solution, etc.) + optional luster/transparency>. The background should be a <laboratory environment: bench surface, basic equipment outlines, avoiding clutter and text labels>.
output: evaluation_points: 1. The container generated in the image is correct and is indeed a conical flask (Erlenmeyer flask) or beaker.

2. The color and appearance of the target substance conform to the description 'a colorless, transparent, viscous, oily liquid'.

3. The substance is contained in the flask/beaker in an appropriate amount, filling no more than half of the container's volume.

4. The background is a simple laboratory bench scene, consistent with the description 'a laboratory environment: bench surface, basic equipment outlines, avoiding clutter and text labels' from the turn 1 input text.

turn: 2
modality: text
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 a strong diprotic acid. 2. It has a very high affinity for water and releases a significant amount of heat when dissolved in water. 3. It is denser than water. Please select from the following options the substance it most likely is:

A. Concentrated Nitric Acid (HNO3)
B. Concentrated Sulfuric Acid (H2SO4)
C. Concentrated Phosphoric Acid (H3PO4)
D. Glacial Acetic Acid (CH3COOH)
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'. When <preparing a dilute solution of the target substance by mixing it with water> the laboratory instrument <glass rod> is used. Please generate an image depicting the correct use of this instrument in this reaction scenario. The background is a simple laboratory bench.
output: evaluation_points: 1. The image correctly depicts the laboratory instrument <glass rod>, and its placement (stirring within a beaker) is reasonable.

2. The reaction substances and conditions shown in the image (concentrated acid being added to water in a beaker, with stirring) conform to the described reaction 'dilution of a concentrated acid'.

3. The use of the <glass rod> conforms to correct usage, placement norms, and safety standards: it is used for gentle stirring to ensure uniform mixing and heat dissipation, not for vigorous agitation.

4. The background is a simple laboratory bench scene, consistent with the description 'a laboratory environment: bench surface, basic equipment outlines, avoiding clutter and text labels' from the turn 1 input text.

turn: 4
modality: text
input: Based on the instrument and operational scene in the input image, determine which of the following statements about this instrument and its usage norms are correct:

A. It is primarily used for transferring solid reagents.
B. When diluting concentrated acids, it should be used to stir the mixture to promote uniform heat distribution.
C. It is typically made of materials resistant to chemical corrosion, such as glass or certain plastics.
D. It can be used to directly measure the volume of a liquid.
E. After use, it should be rinsed with an appropriate solvent (like water) and allowed to air dry or be wiped clean.
F. It is acceptable to use it to vigorously break up solid chunks at the bottom of a beaker.
G. None of the above are correct.
output: answer: B, C, E
