Chemical property

A chemical property is any of a material's properties that becomes evident during a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity. Simply speaking, chemical properties cannot be determined just by viewing or touching the substance; the substance's internal structure must be affected for its chemical properties to be investigated.

Chemical properties can be contrasted with physical properties, which can be discerned without changing the substance's structure. However, for many properties within the scope of physical chemistry, and other disciplines at the border of chemistry and physics, the distinction may be a matter of researcher's perspective. Material properties, both physical and chemical, can be viewed as supervenient; i.e., secondary to the underlying reality. Several layers of superveniency are possible.

Chemical properties can be used for building chemical classifications.

Examples of chemical properties

For example hydrogen has the potential to ignite and explode given the right conditions. This is a chemical property.

Metals in general do they have chemical properties of reaction with an acid. Zinc reacts with hydrochloric acid to produce hydrogen gas. This is a chemical property.

Question:What properties do the share? What properties could you use to distinguish between salt and sugar?

Answers:How about physical property of being a solid. How about white. How about sugar will burn ( a chemical property). Both disolve in water ( a physical property). Salt will not melt but sugar will ( a physical change ). Yeast will act on sugar to from carbon dioxide and ethonal ( a chemical change and booze to boot). Sugar is sweet and salt is not ( physicla property. Salt is an ionic substance and sugar is not, it is a covalent bonded substance. This is a chemical property. Ionic means the molecules of salt are held together by and ionic bond, they give or take electrons. Covalent bonds share electrons.


Answers:Physical: color, weight/mass. Chemical: sucrose is water-soluble and copper isn't, sucrose shatters when struck and copper is malleable, which is the result of bonding types.

Question:Classify each of the following as a physical or chemical property. a.Iron and oxygen from rust. b.Iron is more dense than aluminum. c.Magnesium burns brightly when ignited. d.Oil and water do not mix. e.Mercury melts at -39 C.

Answers:I would say (a) and (c) are chemical properties, as they both represent chemical changes the materials are undergoing. (b), (d), and (e) would be physical properties.

Question:Tell which the words are physical property of chemical property 1. Sodium hydroxide dissolves in water. 2. Hydrochloric acid reacts with sodium hydroxide to produce a salt, water and heat 3. A pellet of sodium is sliced in two. 4. Water is heated and changed to steam. 5. Potassium chlorate decomposes to potasslum chloride and oxygen gas 6. Iron rusts. 7. Ice melts. 8. Acid on limestone produces carbon dioxide gas. 9. Milk sours 10. Wood rots
