Shahid Khan In the realm of science and everyday language, we often encounter terms that appear to be interchangeable but, in fact, have distinct meanings and properties. Such is the case with “fluid” and “liquid.” While these two terms might sound similar and occasionally overlap in casual conversation, they hold unique positions in the world of matter. … Read more
The accuracy of titration results depends on several factors, including the quality of the equipment used, the technique of the experimenter, and the properties of the chemicals involved. In this article, I will discuss some tips that can help improve the accuracy of acid-base titration. Choose Appropriate Equipment The first step in achieving accurate titration … 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
Written by Adeel Abbas Acid-base titration is an important technique used in chemistry to determine the concentration of an unknown acid or base. The titration involves slowly adding a standardized solution of either an acid or a base to the unknown solution until the reaction is complete. To determine the end-point of the reaction, an … Read more

Isotopes are atoms of the same element that have the same number of protons but a different number of neutrons. This means that isotopes have the same chemical properties, but they may have different physical properties, such as mass and radioactivity. Hydrogen, carbon, oxygen, nitrogen, chlorine, iron, uranium, potassium, iodine, and lead all have isotopes. … Read more
Sugar water, vinegar, gasoline, salt water, brass, milk, and Jell-O are some examples of homogeneous mixtures. Also Read: Examples of Heterogeneous Mixtures What are Homogeneous Mixtures? A homogeneous mixture is a mixture in which the components are evenly distributed throughout. These components are so evenly mixed that they cannot be distinguished from each other. This … Read more
Examples of sublimation include dry ice transforming from a solid to a gas without melting, naphthalene balls shrinking as they release vapor, camphor crystals disappearing into vapor, and the disappearance of icicles as they sublimate into water vapor in cold conditions. Examples of Sublimation Here are a few Examples of Sublimation in daily life: 1. Dry … Read more
Written By Adeel Abbas If someone drinks isopropyl alcohol, commonly known as rubbing alcohol, it can have serious health consequences and should be treated as a medical emergency. Isopropyl alcohol is not intended for consumption and can be highly toxic when ingested. What happens when rubbing alcohol enters the body? When isopropyl alcohol enters the … 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
