What is the MSDS for hydrochloric acid?
Inhalation may cause irritation to nose and upper respiratory tract, ulceration, coughing, chest tightness and shortness of breath. Higher concentrations cause tachypnoea, pulmonary oedema and suffocation . Ingestion may cause corrosion of lips, mouth, oesophagus and stomach, dysphagia and vomiting.
Is potassium hydrogen phthalate hazardous?
May be harmful if absorbed through the skin. Ingestion: May cause irritation of the digestive tract. May be harmful if swallowed. Inhalation: May cause respiratory tract irritation.
Is ethanol considered a hazardous material?
Safety Hazards DOT designates typical fuel ethanol per as a Class 3 Flammable Liquid. The Occupational Safety and Health Administration (OSHA) considers typical fuel ethanol a Class IB flammable product.
Is ethanol the same as ethyl alcohol?
Ethanol, also known as ethyl alcohol, drinking alcohol or grain alcohol, is a flammable, colorless, slightly toxic chemical compound, and is best known as the alcohol found in alcoholic beverages.
What PPE is needed for ethanol?
Wear gloves, eye protection and face protection (as needed to prevent skin and eye contact with liquid). Wash hands or liquid-contacted skin thoroughly after handling. Do not eat, drink or smoke when using this product.
What can you not mix with hydrochloric acid?
And by “damage”, we mean third-degree burns. Messing around with chlorine and mixing it with anything is not recommended. Mixing diluted hydrochloric acid and chlorine creates mustard gas.
How does KHP react with NaOH?
A commonly used primary standard for titration with sodium hydroxide solution is the weak acid potassium hydrogen phthalate or KHP (C8H5O4K). In this reaction as well, one mole of KHP completely reacts with one mole of NaOH. The titration of NaOH with KHP involves adding NaOH from the burette to a known volume of KHP.
Is 70% ethanol toxic?
WARNING! Flammable liquid and moderately toxic by ingestion. Flammable liquid, keep away from all ignition sources. Target organs: Eyes, Liver, Kidneys, Central Nervous System.
What is the most significant hazard for ethanol?
Eye: Causes severe eye irritation.
What are two hazards of concentrated hydrochloric acid?
Hydrochloric acid is corrosive to the eyes, skin, and mucous membranes. Acute (short-term) inhalation exposure may cause eye, nose, and respiratory tract irritation and inflammation and pulmonary edema in humans.
What two chemicals should never be mixed?
Bleach and Ammonia = Toxic Chloramine Vapor. Bleach and ammonia are two common household cleaners that should never be mixed.
What happens when you mix nitric acid and ethanol?
Mixtures of ethanol and nitric acid are potentially explosive. This commonly occurs by gas evolution, although ethyl nitrate can also be formed. Methanol is not liable to explosion but it is toxic.
Can you pour ethanol down the sink?
ETHANOL CANNOT BE DISPOSED OF DOWN THE DRAIN AT ANY CONCENTRATION. It must be collected and disposed of as hazardous waste.
Why does KHP need to be dried?
The KHP and acid samples must be dried so that their measured masses are actually proportional to the number of moles of each acid sample. If they were not dried, they’d be heavier than they should with the excess water.
