True solution, colloid, Suspension,experiment – യഥാർത്ഥ ലായനി, കൊളോയിഡ്, സസ്പെൻഷൻ, പരീക്ഷണം

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 …

Classification of mixtures and examples – മിശ്രിതങ്ങളുടെയും ഉദാഹരണങ്ങളുടെയും വർഗ്ഗീകരണം

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 …

Factors that influence solubility – ലയിക്കുന്നതിനെ സ്വാധീനിക്കുന്ന ഘടകങ്ങൾ

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 …

Saturated solution and Unsaturated solution -പൂരിത ലായനിയും അപൂരിത ലായനിയും

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 …

Corrosion of metals – ലോഹങ്ങളുടെ നാശം

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 …
