Examples of homogeneous mixture in the following topics:
-
- The composition of homogeneous mixtures is constant.
- Often separating the components of a homogeneous mixture is more challenging than separating the components of a heterogeneous mixture.
- Distinguishing between homogeneous and heterogeneous mixtures is a matter of the scale of sampling.
- In practical terms, if the property of interest is the same regardless of how much of the mixture is taken, the mixture is homogeneous.
- Mixtures are described as heterogeneous or homogeneous.
-
- The equilibrium constants for homogeneous and heterogeneous solutions need to be calculated differently.
- The former are called homogenous reactions, and the later are called heterogeneous reactions.
- A homogeneous equilibrium is one in which all of the reactants and products are present in a single solution (by definition, a homogeneous mixture).
- Reactions between solutes in liquid solutions belong to one type of homogeneous equilibria.
- The chemical species involved can be molecules, ions, or a mixture of both.
-
- A solution is defined as a homogeneous mixture of both a solute and solvent.
-
- Homogeneous catalysis is a class of catalysis in which the catalyst occupies the same phase as the reactants.
- Catalysts can be classified into two types: homogeneous and heterogeneous.
- Typically, heterogeneous catalysis involves the use of solid catalysts placed in a liquid reaction mixture.
- Acid catalysis, organometallic catalysis, and enzymatic catalysis are examples of homogeneous catalysis.
- An advantage of homogeneous catalysis is that the catalyst mixes into the reaction mixture, allowing a very high degree of interaction between catalyst and reactant molecules.
-
- Diffusion results in the gradual mixing of materials, and eventually, it forms a homogeneous mixture.
-
- Heterogeneous catalysis is a type of catalysis in which the catalyst occupies a different phase than the reaction mixture.
- Catalysts can be divided into two types, homogeneous or heterogeneous, depending on the reaction phase that they occupy.
- Homogeneous catalysts are those that occupy the same phase as the reaction mixture (typically liquid or gas), while heterogeneous catalysts occupy a different phase.
- Generally, heterogeneous catalysts are solid compounds that are added to liquid or gas reaction mixtures.
- For one, heterogeneous catalysts can be separated from a reaction mixture in a straightforward manner, such as by filtration.
-
- An alloy is a mixture or metallic solid solution composed of two or more elements.
- An alloy is a mixture or metallic-solid solution composed of two or more elements.
- Partial solutions give two or more phases that may or may not be homogeneous in distribution, depending on thermal history.
- Partial solutions give two or more phases that may or may not be homogeneous in distribution, depending on thermal history.
- However, for most alloys, there is one particular proportion of constituents, known as the "eutectic mixture," at which the alloy has a unique melting point.
-
- In fact, it was with a gas mixture—ordinary air—that Boyle, Gay-Lussac, and Charles performed their early experiments.
- The mole fraction is a way of expressing the relative proportion of one particular gas within a mixture of gases.
- We do this by dividing the number of moles of a particular gas i by the total number of moles in the mixture:
- The partial pressure of one individual gas within the overall mixtures, pi, can be expressed as follows:
- A mixture of 2 mol H2 and 3 mol He exerts a total pressure of 3 atm.
-
- Mole fraction is the number of molecules of a given component in a mixture divided by the total number of moles in the mixture.
- In a mixture of ideal gases, the mole fraction can be expressed as the ratio of partial pressure to total pressure of the mixture.
- A mixture of gases was formed by combining 6.3 moles of O2 and 5.6 moles of N2.
- What is the mole fraction of nitrogen in the mixture?
- What is the mole fraction of hexane in this mixture?
-
- As noted earlier, chiral compounds synthesized from achiral starting materials and reagents are generally racemic (i.e. a 50:50 mixture of enantiomers).
- Reaction of a racemate with an enantiomerically pure chiral reagent gives a mixture of diastereomers, which can be separated.
- The following diagram illustrates this general principle by showing how a nut having a right-handed thread (R) could serve as a "reagent" to discriminate and separate a mixture of right- and left-handed bolts of identical size and weight.
