Answer and Explanation: Volume is not an additive property because volume is a physical property that depends on the interactions of molecules. For example, in liquids, each component's contribution to the volume is given by a quantity known as molar partial volume.
When the molecules of ISO-propyl alcohol or methanol slip between the water molecules, the volume decreases as the molecules in the mixed liquid become more compacted.
Molecular interactions and molecular forces play a vital part and depending on the nature of these interactions, the solute can decrease or increase the volume. Thus, the proper way of preparing the solution is to dissolve the solute into the solvent and then fill to the mark, as posted earlier in this thread.
Concept: The total mass of substances does not change during a chemical reaction. When one volume of liquid is mixed with another volume of liquid that is less dense than the first, the total volume of the two liquids will not be the sum of the two individual liquids.
So, the answer is: Strong intermolecular interactions between acetone and water molecules are the cause of decrease in volume when they are mixed at room temperature. For more detailed and science behind this subject and related formulations and models, I refer the readers to physical chemistry books.
strictly speaking, No, the volume of the solution is not equal to the sum of the volume of the two components in the solution (solute and solvent). If the solution is an ideal solution and if the two components are both liquid then and only then will the total volume be the sum of the two component volumes.
Volume is not additive because it depends on the interactions of the liquids' molecules. Volume is not additive because it depends on the interactions of the liquids' molecules. Each component's contribution to the volume is given by a quantity called molar partial volume.
The ratio of two extensive properties is always an intensive property. They do no depend upon size or amount of matter. They are not additive in nature. For eg : Density and Pressure.
There is no general law of conservation of volume for example. The initial volume of the hydrogen and oxygen is far greater than the final volume of the water. The fact that mass is conserved really is a deep discovery about the checks and balances that exist in our Universe.
When you mix the rubbing alcohol with water, the latter's molecules make hydrogen bonds with the water molecules. The alcohol dissolves in the water to form a homogenous solution, so you cannot distinguish the alcohol and the water anymore. This occurs because the marker ink is more soluble in the rubbing alcohol.
Water (H2O) is polar because of the bent shape of the molecule. The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule. This is an example of polar covalent chemical bonding.
At the microscopic level, a complete mixing of alcohol and water would entail the two molecules coming together at random to form a single liquid phase without interacting with one another. This means entropy for an alcohol-water solution should substantially increase over the entropy for pure acohol.
Fractional distillation is a method for separating a liquid from a mixture of two or more liquids. For example, liquid ethanol can be separated from a mixture of ethanol and water by fractional distillation. This method works because the liquids in the mixture have different boiling points.
If you mix 50 ml of water with 50 ml of ethanol, the total volume actual equals less than 100 ml. The reason the mixture does not add up to 100 ml is because the molecules that make up ethanol are smaller than the molecules that make up water. So, the ethanol molecules cram themselves between the water molecules.
In a chemical reaction the total mass of all the substances taking part in the reaction remains the same. Also, the number of atoms in a reaction remains the same. Mass cannot be created or destroyed in a chemical reaction.
Ethanol and water, after mixing, can very easily become a homogeneous mixture, because the two liquids are miscible, soluble in all proportions. Ethanol and water, after mixing, can very easily become a homogeneous mixture, because the two liquids are miscible, soluble in all proportions.
When two liquids combine to form a new liquid, we call the liquids “miscible.” When two liquids do not mix together and instead form layers, we call them “immiscible.” The chemical properties of the liquids will determine if they will mix or not. Oil and water are good examples of immiscible liquids.
Intensive properties are properties that do not depend on the quantity of matter. For example, pressure and temperature are intensive properties. Energy, volume and enthalpy are all extensive properties. Their value depends on the mass of the system.
Physical properties are properties that can be measured or observed without changing the chemical nature of the substance. Some examples of physical properties are: boiling point (intensive): the temperature at which a substance boils. melting point (intensive): the temperature at which a substance melts.
It depends on the body's mass distribution and the axis chosen, with larger moments requiring more torque to change the body's rotation rate. It is an extensive (additive) property: for a point mass the moment of inertia is just the mass times the square of the perpendicular distance to the rotation axis.
An extensive property is a property that depends on the amount of matter in a sample. Mass and volume are examples of extensive properties. Color, temperature, and solubility are examples of intensive properties.
Intensive properties are used to identify a substance and do not depend upon the amount of substance (density). Extensive properties depend on the quantity of the substance (mass, volume). Chemical matter properties include flammability and reactivity.
Concentration is an intensive property. The value of the property does not change with scale. Concentration (including molarity) - ratio of amount of solute (mass, volume, or moles) to amount of solution (mass or volume usually) Density - ratio of mass of a sample to the volume of the sample.
An intensive property is a property of matter that does not change as the amount of matter changes. It is a bulk property, which means it is a physical property that is not dependent on the size or mass of a sample. Examples of extensive properties include mass and volume.
Pressure does not depend on the number of particles being measured. Pressure can also be classically defined as Force per unit Area. The ratio of two extensive properties is an intensive property. Force is an extensive property because F = m*a, and mass is extensive (as it depends on the number of particles).
