What is the state symbol for ethanol?
Ethanol, (Symbol C2H5OH) is an organic compound and is the chemical name for alcohol. It is made by fermentation and has a molar mass of 46.06844 g/mol. Ethanol (C2H5OH; drinking alcohol) is an organic compound which is a flammable, volatile liquid. Ethanol is produced from sugar fermentation or petroleum-refining.
Is ethanol a liquid or aqueous solution?
Ethanol: it is a clear, colorless liquid with a characteristic, agreeable odor. In dilute aqueous solution, it has a somewhat sweet flavor, but in more concentrated solutions it has a burning taste.
What is the symbol for aqueous solution?
aq
An aqueous solution forms when a substance dissolves in water. State symbols are useful because they show what a substance is like. For example: H 2O(l) is liquid water but H 2O(g) is steam….State symbols.
| State symbol | Meaning |

| (aq) | Aqueous solution |
How do you know if something is aq?
You can usually tell if something is solid or gas by looking through the problem you are doing (it is normally given) and it is usually marked on the periodic table. You can determine if a solution is aqueous if you see that it is being dissolved in water or if ions/precipitates are involved in a problem.
What is the physical properties of ethanol?
Physical properties Ethanol is a clear, colourless liquid with a characteristic pleasant odour and burning taste. It is highly flammable. Ethanol is used to dissolve other chemical substances and mixes readily with water and many organic liquids.
How is ethanol made by hydration?
Ethanol can also be made by reacting ethene with steam. This process is called hydration. Mixture of ethene and steam is passed over a phosphoric acid catalyst at a temperature of 300°C and 60-70 atmospheres of pressure. The ethanol is condensed as a liquid.
Is ethanol an aqueous?
Ethanol produced either by fermentation or by synthesis is obtained as a dilute aqueous solution and must be concentrated by fractional distillation. Pure ethanol is a colourless flammable liquid (boiling point 78.5 °C [173.3 °F]) with an agreeable ethereal odour and a burning taste.
Is H2O aq or S?
It’s a long phrase, and the abbreviation is (aq). The other states of matter have abbreviations too. Like (s) for solid, (l) for liquid, and (g) for gas. So pure water is liquid, and we say H2O (l).
What does the symbol aq or aqueous mean?
An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. The word aqueous (which comes from aqua) means pertaining to, related to, similar to, or dissolved in, water.
