The annotation, d a°C/b°C, indicates density of solution at temperature a divided by density of pure water at temperature b known as specific gravity. When temperature b is 4 °C, density of water is 0.999972 g/mL.
Filtering your water is an “extra level of assurance” that your water is safe, Kauffman says. But the type of filter you choose matters, John Rumpler , clean water director and senior attorney ...
The eyes are also directly affected and this can cause blindness which is found in many people exposed to high levels of methanol." So far, five of the six who have died have been women .
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
What is methanol? Methanol, a colourless liquid with a faintly sweet pungent smell, completely mixes with water. It’s very similar to ethanol – the pure form of alcohol in alcoholic drinks.
Methanol and its vapours are flammable. Moderately toxic for small animals – Highly toxic to large animals and humans (in high concentrations) – May be fatal/lethal or cause blindness and damage to the liver, kidneys, and heart if swallowed – Toxicity effects from repeated over exposure have an accumulative effect on the central nervous system, especially the optic nerve – Symptoms may ...
The deaths of five tourists after apparently drinking tainted drinks highlight the wider issue of bootleg alcohol.
