homogeneous solution
(noun)
A solution composed of matter that all exists in the same state.
Examples of homogeneous solution in the following topics:
-
Homogeneous versus Heterogeneous Solution Equilibria
- 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 phases may be any combination of solid, liquid, or gas phases, and solutions.
-
Molality
- Molality is a property of a solution that indicates the moles of solute per kilogram of solvent.
- Molality is an intensive property of solutions, and it is calculated as the moles of a solute divided by the kilograms of the solvent.
- It is easy to calculate molality if we know the mass of solute and solvent in a solution.
- This is true for all homogeneous solution concentrations, regardless of if we examine a 1.0 L or 10.0 L sample of the same solution.
- With this information, we can divide the moles of solute by the kg of solvent to find the molality of the solution:
-
Osmotic Pressure
- A solution is defined as a homogeneous mixture of both a solute and solvent.
- Solutions generally have different properties than the solvent and solute molecules that compose them.
- Some special properties of solutions are dependent solely on the amount of dissolved solute molecules, regardless of what that solute is; these properties are known as colligative properties.
- If a solution consisting of both solute and solvent molecules is placed on one side of a membrane and pure solvent is placed on the other side, there is a net flow of solvent into the solution side of the membrane.
- Discuss the effects of a solute on the osmotic pressure of a solution

Introduction to The Four Fundamental Spaces
- Another fundamental subspace associated with any matrix $A$ is composed by the solutions of the homogeneous equation $A\mathbf{x} = 0$ .
- Well, take any two such solutions, say $\mathbf{x}$ and $\mathbf{y}$ and we have

Homogeneous Catalysis
- 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.
- Acid catalysis, organometallic catalysis, and enzymatic catalysis are examples of homogeneous catalysis.
- Most often, homogeneous catalysis involves the introduction of an aqueous phase catalyst into an aqueous solution of reactants.
- However, unlike with heterogeneous catalysis, the homogeneous catalyst is often irrecoverable after the reaction has run to completion.
-
Alloys
- An alloy is a mixture or metallic solid solution composed of two or more elements.
- Complete solid solution alloys give single solid phase microstructure.
- Partial solutions give two or more phases that may or may not be homogeneous in distribution, depending on thermal history.
- Complete solid solution alloys give single solid phase microstructure.
- Partial solutions give two or more phases that may or may not be homogeneous in distribution, depending on thermal history.

Applications of Second-Order Differential Equations
- Examples of homogeneous or nonhomogeneous second-order linear differential equation can be found in many different disciplines, such as physics, economics, and engineering.
- Therefore, we end up with a homogeneous second-order linear differential equation:
- A solution of damped harmonic oscillator.
- Identify problems that require solution of nonhomogeneous and homogeneous second-order linear differential equations
-
Nonhomogeneous Linear Equations
- When $f(t)=0$, the equations are called homogeneous second-order linear differential equations.
- Examples of homogeneous or nonhomogeneous second-order linear differential equation can be found in many different disciplines such as physics, economics, and engineering.
- In general, the solution of the differential equation can only be obtained numerically.
- However, there is a very important property of the linear differential equation, which can be useful in finding solutions.
- Linear differential equations are differential equations that have solutions which can be added together to form other solutions.
-
Substances and Mixtures
- Mixtures take the form of alloys, solutions, suspensions, and colloids.
- 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 Chi-Square Distribution: Test for Homogeneity
- A different test, called the Test for Homogeneity, can be used to make a conclusion about whether two populations have the same distribution.
- To calculate the test statistic for a test for homogeneity, follow the same procedure as with the Test of Independence.
- We cannot use the Test for Homogeneity to make any conclusions about how they differ.
