The best metal for electrical conductivity is silver. Silver is the most conductive metal, with a conductivity of 63 x 10^6 siemens per meter (S/m) at room temperature. This means that electricity can easily flow through silver, making it an excellent choice for electrical applications. However, silver is expensive and can tarnish easily, so it … Read more
A separating funnel is a laboratory apparatus that is commonly used to separate two immiscible liquids that have different densities. Here are some examples of mixtures that can be separated using a separating funnel: 1: Oil and water Oil and water are immiscible liquids that have different densities, making them easy to separate using a … Read more

Written By Adeel Abbas A fundamental aspect of our world is that chemical changes take place. They transform one substance into another. All these changes can be observed in a variety of natural and human-made processes, from the rusting of iron to the burning of fossil fuels. The list of chemical changes in this chapter … Read more
Written by Adeel Abbas Condensation is a natural process that occurs when a gas or vapor transitions into a liquid state. We often see this happen in nature, from dew forming on the grass in the morning to fogged car windows. In this article, we will explore ten examples of condensation and how they occur. … Read more
Chromatography is a powerful separation technique that is widely used in a variety of fields, including chemistry, biochemistry, pharmaceuticals, and forensics. A chromatography method for separating mixtures into their individual components. In this method, a mixture is separated into its different components based on their different interactions with a stationary phase and mobile phase. These … Read more
Written By Adeel Abbas Distillation is a common method of separating mixtures. It involves heating a mixture to vaporize one or more of its components and then cooling and condensing the vapor. Here are 20 examples of mixtures that can be separated by distillation. Examples of mixtures that can be separated by distillation 1: Ethanol … Read more
Written By Adeel Abbas What is Thin Layer Chromatography? Thin layer chromatography (TLC) is a widely used separation technique in analytical chemistry that is used to separate and identify different compounds present in a mixture. TLC is a quick and easy-to-use method that is used for qualitative and quantitative analysis of a wide range of … Read more
Written by Adeel Abbas A mole is a unit of measurement in an International system unit (SI) that represents a specific amount of substance. 6.02 × 1023 Particles make up one mole, simply just like twelve eggs make a dozen. The number 6.02 × 1023 is known as Avogadro’s number and is represented as NA. … Read more
