Difference Between Acetone and Water

What is Acetone?

Acetone is the simplest ketone, also known as dimethyl ketone or propanone. Its chemical formula is C3H6O. The acetone is a colorless, highly flammable liquid with a specific odor.

Acetone is produced by the moderate oxidation of 2-propanol in the presence of a copper catalyst.

It can be dissolved in water, ethanol, ester, and other solvents.

The most common use of acetone is in domestic nail polish cleaner. It is also used in the production of plastics, film strips, acetate silk, synthetic rubber, smokeless gunpowder, some medicines, etc. As a good solvent for many polar and non-polar organic compounds, it is used to clean contaminated surfaces, as a solvent for paints, varnishes, various organic synthetic reactions, etc. Many of the plastics dissolve or swell in acetone.

Acetone occurs in animals, plants, vehicle exhaust, forest fires, volcanic gases, etc.

Acetone occurs in the human body in small quantities. After prolonged starvation or diet the stock of carbohydrates in the body is depleted and the fat is decomposed, which leads to the production of acetone. As a result, the so-called “acetone breath” occurs. More severe cases result in ketoacidosis, which is also one of the symptoms of diabetes.

Inhaled acetone vapor causes dizziness and intoxication. Acetone dissolves fats very well, so it causes dry and cracked skin.

The molecular weight of acetone is 58.08 g/mol. Its vapors are two times heavier than air. The density of acetone related to water is 0.8 (water = 1). It is stable under the recommended storage conditions.

Acetone’s boiling point is 56°C, and its melting point is -95°C. Auto-ignition occurs at 465°C.

 

What is Water?

Water is an inorganic compound with a chemical formula H2O. At room temperature, it is a transparent, odorless, and colorless liquid.

In general, the water is derived from the available natural sources. However, alternative water extraction technologies are developed for dry areas where no water sources are available. For example in Morocco is built the world’s largest system for extracting water from the air by fog condensation, covering over 600 square meters.

In Europe about 42% of utilized water is used in agriculture, 32% for industrial needs, 18% for energy production, and 8% for domestic purposes. In the US about 70% of the utilized water is used in agriculture, around 22% for industrial needs and power production, and about 8% – for domestic purposes.

Water covers about 71% of the surface of the Earth, mostly in oceans and seas. About 1.7% of the water occurs as groundwater and 1.7% of it is frozen in glaciers and the ice caps.

In the human body, there are about 70 – 75% of water. The amount may slightly vary and the following general dependencies are observed:

  • Babies and children have a higher percentage of water than adults;
  • Women have a smaller percentage of water than men;
  • Overweight people have a smaller percentage of water than those of normal weight.

All life processes in the human body are connected with water. Water dissolves nutrients, removes waste products. It provides metabolism and is the environment in which all biochemical processes take place.

The water is one of the least toxic compounds. However, if it is being consumed in a high quantity without adequate electrolyte intake water intoxication can occur.

The molecular weight of the water is 18.02 g/mol. Its vapors are lighter than air.

Water’s boiling point is 100°C, and its melting point is 0°C. Water is a stable compound. It is not combustible and cannot be ignited.
