Mixtures and Solutions
Words to Know
Mixture / The act or process of mixing
Solute / what is being dissolved
Solution / A homogeneous mixture of two or more substances, which may be solids, liquids, gases, or a combination of these.
Solvent / the dissolver

What is the difference between a mixture and a solution?
A solution is a homogeneous mixture. So a solution is a specific type of mixture while a mixture doesn't tell you the type.
ANSWER
A homogeneous mixture does not scatter light and its particles can not be separated by filtration. Its particle size is about109cm. Its particles are very difficult to differentiate even under a microscope. A homogeneous mixture shows the properties of its components and does not show the Tyndall effect. It is also called a solution. The mixture is very stable, i.e., its particles do not settle, or separate. The definition of homogenous strongly depends on the context used. For example, in geology a homogeneous rock could be made from microscopic grains of several minerals which show strongly varying properties. In chemistry, a homogeneous suspension of material means that per volume the same amount of material is suspended in the substance, although it might be possible to see the particles under a microscope. A homogeneous solution has one phase (liquid) although the solute and solvent can vary, for example salt water. In Chemistry, another homogeneous substance is the surrounding air around you. It is equally suspended, and the particles and gases and liquids cannot be analyzed separately or pulled apart; simply, it is very consistent.in finaly we can conclude mixtures are two or more subatances mix together without considering any ratios.& no chemical reaction were occour.
A heterogeneous mixture is a mixture of two or more compounds. Examples are: mixtures of sand and water or sand and iron filings, a conglomerate rock, water and oil, a salad, trail mix, and concrete (not cement). During the sampling of heterogeneous mixtures of particles, the variance of the sampling error is generally non-zero. Gy's sampling theory [1] quantitatively defines the heterogeneity of a particle as: h_i = \frac{(c_i - c_\text{batch})m_i}{c_\text{batch} m_\text{aver}} . where hi, ci, cbatch, mi, and maver are respectively: the heterogeneity of the ith particle of the population, the mass concentration of the property of interest in the ith particle of the population, the mass concentration of the property of interest in the population, the mass of the ith particle in the population, and the average mass of a particle in the population. In chemical kinetics, a heterogeneous reaction is one that takes place at the interface of two or more phases, i.e. between a solid and a gas, a liquid and a gas, or a solid and a liquid. In heterogeneous catalysis the catalyst is in a different phase from the substrate.
