Yes, it is always poisonous.
The main components of antifreezes are:
- Methanol (mainly in windshield antifreeze) - lethal dose is about 6 g/kg body weight. Even before you reach the lethal dose it can kill optic nerves (make you blind) and destroy your liver.
- Propylene Glycol (PG) - main ingredient in "safer" forms of engine antifreeze/ coolants. While it is only about 1/3 as toxic to dogs (who may try to lick up spills because it tastes good to them) the oral LD50 (the dose that will kill 50% of dogs who get that much) of PG in dogs is 22g/k. Consuming PG can result in acidosis, liver damage, and renal insufficiency. Clinical signs of a propylene glycol toxicoses include CNS depression, weakness, ataxia, and seizures. With large ingestion, diuresis and supportive care, such as treatment for acidosis, should be given.
- Ethylene glycol (EG) - the most dangerous form of antifreeze. Most commercial antifreeze products contain between 95-97% ethylene glycol. The minimum lethal dose of undiluted ethylene glycol antifreeze is 4.4-6.6ml/kg in dogs and 1.4ml/kg in cats. The lethal dose in people is about 5 or 6 g/kg. EG can cause metabolic acidosis and acute renal tubular necrosis. In most cases of ethylene glycol poisonings, vomiting is seen within the first few hours and then within 1-6 hours signs of depression, ataxia, weakness, tachypnea, polyuria, and polydipsia occur. By 18-36 hours acute renal failure occurs.
What else can I help you with?
Why cars use of antifreeze in summer?
Antifreeze also raises the boiling point, has lubricants for the water pump, and has corrosion inhibitors in it.
Is boiling antifreeze always a sign of overheating?
Yes unless you are out in space.
What people would want to use antifreeze treatment?
No one, antifreeze is poisonous and is not a treatment for anything other than preventing an engine from freezing.
What can antifreeze do to the boiling point of the water in a car's radiator?
Antifreeze raises the boiling point of water in a car's radiator by reducing the vapor pressure of the coolant mixture. This helps prevent the engine from overheating by allowing the coolant to operate at higher temperatures before boiling.
How does an antifreeze prevent freezing in cold months and overheating and boiling?
It lowers the freezing point and raises the boiling point of water.
What 2 things does antifreeze change?
because.... 333246 is the answer NOT!! :)
What happens when Antifreeze is heated?
When antifreeze is heated, it changes from a liquid to a gas. This process is known as vaporization. If antifreeze is heated beyond its boiling point, it can produce harmful vapors and potentially lead to a dangerous situation due to the toxicity of the chemicals in antifreeze.
What are physical changes of antifreeze when dissolved in water?
will change the boiling and freezing point of the water
Does adding antifreeze to a car radiator increase the boiling point of the water in the radiator?
Yes
How does antifreeze keep the water in your radiator from freezing and overheating?
It changes the freezing and boiling point.
What is the application of Boiling point elevation?
Boiling point elevation is used in various applications such as in cooking to increase the boiling point of water by adding salt, in chemical processes to separate and purify substances based on their boiling points, and in antifreeze solutions to prevent freezing of liquids at lower temperatures.
What temperature does antifreeze and water boil?
Antifreeze, typically made of ethylene glycol or propylene glycol, has a higher boiling point than water. While water boils at 100°C (212°F) at standard atmospheric pressure, a mixture of antifreeze and water can have a boiling point ranging from approximately 107°C to 115°C (225°F to 239°F), depending on the concentration of antifreeze. This elevated boiling point helps prevent overheating in engines and other systems.
