A colloid is a mixture of two substances, one of which is finely divided and dispersed evenly throughout the other. Examples of colloids include fog, whipped cream, and paint. A suspension is a mixture of two substances, one of which is larger and more dense than the other, and which settle out of the mixture …
Mixtures are substances that are made up of two or more components that are not chemically combined. Mixtures can be classified into two broad categories: homogeneous mixtures and heterogeneous mixtures. Homogeneous Mixtures: These mixtures have a uniform composition throughout and form a single phase. Examples include air, salt water, and alloys. Heterogeneous Mixtures: These mixtures …

To grow a crystal, you need a supersaturated solution of the desired material. To make this solution, the material must be dissolved in a solvent, such as water, until no more can be dissolved. The solution is then heated to encourage further dissolution and then cooled slowly while stirring until the material precipitates out in …
1. Temperature: Increasing temperature generally increases solubility, as more molecules of a solute can be dissolved in a solvent at higher temperatures. 2. Pressure: Increasing pressure can increase the solubility of a gas in a liquid. 3. Nature of the Solvent: The polarity of the solvent can affect the solubility of a solute. Polar solvents …

Super saturation is a term used to describe a solution that contains a higher solute concentration than is able to be held in the solvent. This means that the solution is in a state of imbalance and that the solute is likely to precipitate out of the solution. A common example of super saturation is …
Saturated solution A saturated solution is a solution that contains the maximum amount of solute that can be dissolved in a given solvent at a given temperature. This occurs when the chemical potential of the solute and solvent are equal. Saturated solutions are in a state of dynamic equilibrium and further addition of solute will …

The concentration of a solution is a measure of how much of a solute is dissolved in a given amount of a solvent. It is usually expressed as a mass or volume fraction, or as moles of solute per liter of solution. The concentration of a solution can be changed by adding more solute or …
Suggest different methods to prevent corrosion of iron ? Painting/Coating: Applying a protective coating such as paint, plastic, or other materials to iron can help to prevent corrosion. Galvanizing: This is a process of coating iron with zinc to form a protective layer. This helps to prevent corrosion and rusting. Cathodic Protection: This involves connecting …
Corrosion is the gradual destruction of material, usually metals, by chemical reaction with its environment. In the most common use of the word, this means electrochemical oxidation of metals in reaction with an oxidant such as oxygen. Rusting of iron experiment Fill four test tubes with water. Place an iron nail in each test tube …
