Question

There are several hazards associated with the chemicals in the qualitative analysis experiment. for each chemical, identify the associated hazards. (select all that apply.) hazard 0.1 m ag+ 0.1 m ba2+ 0.1 m fe3+ 6 m hcl 6 m h2so4 6 m hno3 7.5 m nh3 corrosive irritating vapors toxic if ingested causes staining on skin flammable none listed

Answer 1

You can determine the hazards of these chemicals by looking at their material data safety sheets (MSDS). 

1. 0.1 M Ag⁺: Silver compounds are absorbed by skin causing bluish pigmentation. Thus, it causes staining on skin. Also, liquid vapor may be irritating to skin and also moderately toxic when ingested.

2. 0.1 M Ba²⁺: This is mildly toxic when ingested causing stomach irritation, muscle weakness, swelling of organs like brain, liver, kidney and heart.

3. 0.1 M Fe³⁺:Iron is corrosive, has irritating vapor especially to the eyes, and toxic if ingested.

4. 6 M HCl: This is a concentrated strong acid, so it is corrosive, has irritating vapors, flammable and toxic when ingested.

5. 6 M H₂SO₄: This is also a concentrated strong acid. Moreover, it is a strong oxidizing agent. So, its hazards include: corrosive, has irritating vapors, toxic when ingested and causes staining on skin.

6. 6 M HNO₃: This is a concentrated strong acid, so it is corrosive, has irritating vapors, flammable and toxic when ingested.

7. 7.5 M NH₃: This is a weak base. It is characterized for its pungent odor. This is corrosive, has irritating vapors, toxic if ingested, and flammable.
