Case Study Sodium Bicarbonate
a) What other name(s) does this chemical go by? (i.e. synonyms)
Other names for sodium bicarbonate are baking soda, sodium hydrogen carbonate, and carbonic acid sodium.
(b) What is the type(s) of hazard associated with this chemical? (i.e. poisonous, biohazardous, ...)
According to the Globally Harmonized System (GHS) of Classification and Labeling of Chemicals, sodium bicarbonate has not been categorized as hazardous.
(c) What should you do if this chemical splashes in your eyes or is spilled on your skin?
If the chemical splashes in the eyes, immediately remove contact lenses (if any). Next, splash the eyes thoroughly with water for 15 minutes, while regularly raising the upper and lower eyelids. It is also important to immediately seek …show more content…
Two health issues that could be caused by this chemical are that when inhaled, excessive dust may irritate the respiratory tract and also if contacted with eyes, the chemical may cause slight irritation. If sodium bicarbonate is inhaled, symptoms may include coughing and sneezing.
(j) Are there any environmental concerns with this chemical?
There are not any environmental concerns with this chemical.
(k) Describe how you would decompose sodium bicarbonate. In your description include a temperature at which NaHCO3 would decompose.
Sodium bicarbonate will start decomposing when heated at a temperature of 80°C. This process and reaction is called thermal decomposition.
(l) Describe the expected behaviour during/after reaction.
The thermal decomposition of sodium bicarbonate would result in the following being produced: carbon dioxide, water, and sodium carbonate. When this decomposition progresses, water will condense on the sides of the test tubes as a physical description and result of the reaction. The sodium bicarbonate will eventually turn into sodium carbonate (baking powder) when heated towards higher temperatures (200°C); which can be further decomposed or
