What is glacial acetic acid and how does it differ from acetic acid?
Glacial acetic acid is a trivial name for water-free acetic acid. Usually acetic acid containing usually less than 1 percent of water Glacial acetic acid is anhydrous form of acetic acid in which it exists in dimmer form. It's known as Glacial because on freezing it forms needle shape crystals
Act as solvent: -Glacial acetic acid is a poor nucleophile, which indicates a relatively low possibility of causing unwanted substitution reactions. -Glacial acetic acid is a polar solvent which can solve polar acetanilide. -Glacial acetic acid is concentrated acetic acid. We can dilute it to whatever degree we want, which is convenient. -Glacial acetic acid provides acid environment that would not neutralize nitric acid.
Glacial acetic acid is a trivial name for water-free acetic acid, which is the more common name for (a solution of) ethanoic acid (CH3COOH). So in its most purest liquid state. Especially the food grade, 4% to 10%, acetic acid solution is called "vinegar" and is of natural oxidative alcoholic fermentation origin.
If 15.0 of glacial acetic acid is diluted to 1.40 with water what is the of the resulting solution the density of glacial acetic acid is 1.05?
You are leaving out some vital information here. Numbers have no applicability to chemical problems unless they have units attached. So, you could have 15.0 milliliters of glacial acetic acid, or 15.0 moles of glacial acetic acid, or 15.0 grams of glacial acetic acid, but you can't have 15.0 of glacial acetic acid, it doesn't mean anything. You have three different numbers in the above question, with no units attached to any of them. Numbers…
Acetic acid is the chemical that gives vinegar its characteristic smell and taste. "Glacial" means water-free (no H2O). Glacial acetic acid is simply "pure" acetic acid. It is very strong and will burn the skin. Normal vinegar is mostly water with about 5% acetic acid. Glacial acetic acid should be a safe additive in food as long as the final concentration is less than 25%.
