What is extensive and intensive property |
| Answer» Intensive Properties :Intensive properties are bulk properties, which means they do not depend on the amount of matter that is present. Examples of intensive properties include: Boiling point, Density, State of matter ,Color, Melting point, Odor, Temperature ,Refractive Index ,Luster, Hardness, Ductility, Malleability .Intensive properties can be used to help identify a sample because these characteristics do not depend on the amount of sample, nor do they change according to conditions.\xa0Extensive Properties: Extensive properties do depend on the amount of matter that is present. An extensive property is considered additive for subsystems.Examples of extensive properties include: Volume, Mass, Size ,Weight, Length.The ratio between two extensive properties is an intensive property. For example, mass and volume are extensive properties, but their ratio (density) is an intensive property of matter. While extensive properties are great for describing a sample, they aren\'t very helpful identifying it because they can change according to sample size or conditions. | |

Which salt is used for carbonate test |
| Answer» Carbonate ions, CO32- can be detected whether in a solid compound or in solution. An acid, such as dilute hydrochloric acid, is added to the test compound. Carbon dioxide gas bubbles if carbonate ions are present. Limewater is used to confirm that the gas is carbon dioxide. It turns from clear to milky when carbon dioxide is bubbled through. One can use cadmium carbonate,sodium carbonate e.t.c to detect carbonate...Any salt that contains carbonate can be used to carry carbonate test. | |
