turn: 1
modality: image
input: Generate a concise chemical laboratory bench scene: A substance is contained in a <correct and appropriate laboratory container type>. The substance must exhibit <observable appearance description of the target substance: must include color + physical state (solid/liquid/gas) + form (powder/lump/crystal/solution, etc.) + optional luster/transparency; the name, chemical formula, or element symbols of the substance are prohibited>. The background should be a <laboratory environment: bench surface, outlines of basic equipment, avoid clutter and text labels>.
output: evaluation_points: 1. The container generated in the image is correct and is indeed a brown glass reagent bottle with a ground glass stopper.

2. The color and appearance (powder/crystal/lump/solution, etc.) of the target substance conform to 'colorless, clear, transparent liquid solution'.

3. The substance is stored in the container in the correct manner (the bottle is tightly stoppered), and the fill level is appropriate.

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 has the following properties: 1) It is highly soluble in water, and its concentrated aqueous solution has a strong, pungent odor. 2) It is a weak base that can react with acids to form salts. 3) It is volatile at room temperature. Please select the substance it most likely is from the following options:

Options:
A. Concentrated Sulfuric Acid (H2SO4)
B. Sodium Hydroxide Solution (NaOH, aq)
C. Ammonia Solution (NH3·H2O)
D. Ethanol (C2H5OH)
E. None of the above
output: answer: C

input: We will subsequently refer to the substance you identified in the previous text as the 'target substance'. The target substance can undergo <a reaction with dilute hydrochloric acid, producing a gas>. Please generate the state of the laboratory 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 the experimental apparatus are correct and match the <reaction of ammonia solution with dilute hydrochloric acid>.

2. The target substance is generated in the correct form (colorless liquid) at the correct location in the image, and its color, state, etc., conform to the characteristics of 'ammonia solution, a colorless liquid'. It is shown in a container like a beaker or flask.

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

4. The reaction phenomenon conforms to 'bubbles of a colorless gas evolving from the reaction mixture'. The reaction is typically demonstrated by bringing a moist red litmus paper near the mouth of the container, which should turn blue.

5. The image background is a laboratory bench.

input: If, in the above normal reaction, the experimental setup is incorrectly modified such that <the gas delivery tube is inserted directly into the dilute hydrochloric acid solution without a proper funnel or safety bulb to prevent backflow>, the most likely accident to occur is:

Options:
A. The reaction mixture catches fire.
B. Back-suction of the liquid into the ammonia solution container, potentially causing it to crack or leading to a violent secondary reaction.
C. The apparatus explodes due to a rapid pressure increase.
D. Toxic chlorine gas is released.
E. None of the above
output: answer: B

input: Regarding the experimental accident described in the previous question, the most correct course of action is:

Options:
A. Immediately add water to dilute the mixture.
B. Evacuate the area and call emergency services, as a toxic gas leak is suspected.
C. If safe to do so, first disconnect or clamp the tubing to stop the backflow, then carefully assess the situation (check for container damage, spills) while wearing appropriate PPE (gloves, goggles, lab coat).
D. Attempt to neutralize the mixture by adding a strong base.
E. None of the above
output: answer: C
