Final answer:
For 6.0 M nitric acid, the applicable GHS pictograms are 'Corrosive' and 'Oxidizing' due to its ability to burn skin and eyes, as well as intensifying combustion. Option 1,2 are correct.
Step-by-step explanation:
The student has asked which GHS pictograms apply to 6.0 M nitric acid. There are several possibilities, but based on its properties, the appropriate GHS pictograms for nitric acid are:
Corrosive—due to its ability to cause severe skin burns and eye damage upon contact, as well as being very damaging if inhaled.
Oxidizing—because nitric acid can release oxygen and cause or intensify the combustion of other materials.
Nitric acid is not generally classified under the explosive, flammable, or toxic hazard categories for the purposes of GHS labeling at this concentration and form, although it is indeed harmful and should be handled with care.
Nitric acid is a corrosive acid and a powerful oxidizing agent. It is classified as Corrosive, Oxidizing, and Toxic. The GHS pictogram phrases that apply to 6.0 M nitric acid are:
Corrosive: Chemicals with this label can burn your skin and eyes and burn holes in your clothes.
Oxidizing: Nitric acid is a powerful oxidizing agent, meaning it can react strongly with other substances.
Toxic: Concentrated nitric acid can cause chemical burns and is toxic to living organisms.
