Examine these two MSDS from different manufacturers for sodium hydroxide (NaOH). Compare and contrast the following aspects: chemical names, chemical properties, order of components, health hazards, and proper disposal. Click on each of the links to examine two MSDS reports from different sources. Sodium Hydroxide Version 1 Sodium Hydroxide Version 2

In #1) Chemical Name: Sodium hydroxide, Chemical Formula: Na OH, Synonyms: Caustic soda, Sodium hydrate. General: Corrosive to metals and tissue. Noncombustible solid. Soluble in water. When in contact with water, may generate sufficient heat to ignite combustible materials.Health Hazard: Strong corrosive action on contacted skin. Causes eye and skin burns. Causes digestive and respiratory tract burns. Reactivity: Water, acids, flammable liquids, metals such as aluminum, tin, and zinc.Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider the material's impact on air quality, potential migration in soil or water, effects on animal and plant life, and conformance with environmental and public health regulations.  

#2) Product Name: Sodium hydroxide, pellets

Chemical Name: Sodium Hydroxide

Synonyms: Lye, Caustic soda, Soda lye

Health Hazard: Causes severe burns to eyes, skin, and mucus membranes.

Target Organs: Eyes, skin, respiratory system

Hazard Summary: When dissolved in water or neutralized with acid, it liberates substantial heat, which may be sufficient to ignite combustible materials. Sodium hydroxide is very corrosive.

Waste Disposal: Waste must be disposed of in accordance with federal, state, and local environmental control regulations.

Explanation:

I just did this by stating what I observed then copy and pasted the info it asked for the only one I didn't get was order of compounds. Anyways hope this helps.

water pollution kills aquatic life. aquatic life includes algae and other plant life that use photosynthesis. photosynthesis takes   c02 out of the air.  

c02is a greenhouse gas.
