Crystal methamphetamine (‘ice’, ice drug) is a stimulant drug, which means it speeds up the messages travelling between the brain and the body. It’s stronger, more addictive and therefore has more harmful side effects than the powder form of methamphetamine known as speed.

The meaning of pure The word ‘pure’ is used in chemistry in a different way from its everyday meaning. In chemistry: a pure substance consists only of one element or one compound. a mixture consists of two or more different substances, not chemically joined together.

Here are a few more examples:

• Smoke and fog (Smog)
• Dirt and water (Mud)
• Sand, water and gravel (Cement)
• Water and salt (Sea water)
• Potassium nitrate, sulfur, and carbon (Gunpowder)
• Oxygen and water (Sea foam)
• Petroleum, hydrocarbons, and fuel additives (Gasoline)

It contains a number of compounds that are physically combined and are now in a uniform state which is solid. A sample of that butter will always have the same abundance of the compounds that comprise it. Therefore, butter, though a colloid, is a type of mixture and to be more specific, a homogenous mixture.

Pure substances contain only one type of particle. These substances are characterized by a certain atomic ratio and are referred to as chemical compounds. Pure compounds for example are water (H2O), carbon dioxide (CO2), acetone (C3H6O) or cementite (Fe3C).

Acetone is one of the ketone bodies, and is used as a solvent in many pharmaceutical and commercial preparations. Acetone is an organic compound with the formula (CH3)2CO. In medicine, dermatologists use acetone with alcohol for skin treatments for acne.

Acetone is a weak Lewis base that forms adducts with soft acids like I2 and hard acids like phenol.

Your body makes small amounts of acetone. You can be exposed to a small amount of acetone by breathing air, drinking water, and eating food with acetone. You can also be exposed by contact with household chemicals with acetone.

Breathing moderate to high amounts of acetone for a short amount of time can irritate your nose, throat, lungs and eyes. It can also cause headaches, dizziness, confusion, a faster pulse, nausea, vomiting, effects on the blood, passing out and possible coma, and a shorter menstrual cycle in women.

If you smell acetone in your home, it’s a sign that there could be a refrigerant leak. While this ruins the effectiveness and efficiency of your HVAC system, it can also pose a health hazard and even a fire hazard if it’s exposed to an open flame.
