Answer 3

Potential Acute Health Effects: Hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, of inhalation
(lung irritant).
Potential Chronic Health Effects:
Slightly hazardous in case of skin contact (sensitizer).

The substance may be toxic to upper respiratory tract, skin, eyes.
Repeated or prolonged exposure to the substance can produce target organs damage.

Products of Combustion: Emits Na2O fumes when heated to decompositon.
Special Remarks on Fire Hazards:
Sodium carbonate can ignite and burn fiercely in contact with fluoride.
Sodium Carbonate in contact with fluorine decomposed at ordinary temperature with incandescence.
Special Remarks on Explosion Hazards:
Reacts explosively with red-hot aluminum metal.
Sodium carbonate + ammonia in arabic gum solution will explode.
Conditions of Instability: Incompatible materials, moisture
Incompatibility with various substances:
Reactive with acids.
Slightly reactive to reactive with moisture.

Hygroscopic. Combines with water with evolution of heat.
Incompatible with phosphorus pentoxide, lithium, fluorine, fluoride, ammonia + silver nitrate, 2,4,6-trinitrotoluene,
ammonia, acids, sodium sulfide + water, hydrogen peroxide, red hot alumium metal, sodium sulfide, zinc, calcium
hydroxide.
Sodium Carbonate is decomposed by acids with effervescence.
Reacts violently with F2, Lithium, and 2,4,6-trinitrotoluene.

Special Remarks on Corrosivity: Hot concentrated solutions of sodium carbonate are mildly corrosive to steel.
Chronic Effects on Humans: May cause damage to the following organs: upper respiratory tract, skin, eyes.

Special Remarks on Chronic Effects on Humans: May cause adverse reproductive effects based on animal test data
Special Remarks on other Toxic Effects on Humans:
Acute Potential Health Effects:
Skin: Causes skin irritation with possible burns depending on the concentration, site (abraded or intact skin), and
duration of exposure.
Eyes: Causes eye irritation and possible burns. Concentrated solutions may cause permanent corneal injury
(permanent corneal opacity).
Ingestion: Sodium carbonate ingestion may cause irritation of the digestive tract resulting in nausea, vomiting,
diarrhea, thirst, abdominal pain depending on concentration and amount ingested. May also affect the
cardiovascular system .
Inhalation: Dust may cause respiratory tract and mucous membrane irritation with coughing and shortness of
breath (dyspnea), pulmonary edema.
Chronic Potential Health Effects:
Chronic inhalation may result in decreased pulmonary function, nasal congestion, nosebleeds, perforation of the
nasal septum. Other effects of chronic exposure are skin (dermatitis and ulceration), and gastrointestinal
complaints. However, the effects of chronic exposure seem to be reversible if exposure is decreased.
