What is the formula of mean particle size?
The formula for mean particle size is calculated by summing the individual particle sizes and dividing by the total number of particles. Mathematically, it is expressed as mean particle size = (Σ particle sizes) / total number of particles.
Why doesn't starch dissolve in water?
if we dissolve a starch in water it forms a colloidal solution and the particle size is much larger to completely dissolve in water
Principle behind the process of solution and filtration as a mean of seeparation?
Solution and filtration are methods of separation based on the differences in solubility and particle size, respectively. In solution, components are dissolved in a solvent, and can be separated based on their solubility through techniques like crystallization or evaporation. Filtration, on the other hand, involves passing a mixture through a filter to separate components based on their particle size, with smaller particles passing through the filter while larger ones are retained.
Is chalk in water a suspension?
yes,it is a suspension because it is a heterogeneous mixture which is given in the question so it can not be a true solution. in the case of suspension the chalk powder in water is insoluble and the particle size is more than 2000 but in colloidal solution both in dispersed phase and dispersed medium the particles are soluble. so, it is a suspension.generally chalk powder in water is insoluble
How big is a particle?
Particles can vary in size depending on the type of particle. For example, an atom is about one angstrom in size, while a typical virus particle can range from 20 to 400 nanometers. In contrast, a dust particle might be around 10 micrometers in size.
In a colloid solution or suspension particles are dispersed throughout the mixture. What is the order of these three types of mixtures from the smallest particle size to the largest?
The order from smallest particle size to largest particle size is: solution (smallest), colloid, suspension (largest).
How can a mixture be classified as a solution suspension or a colloid?
based on size of its largest particle
What is the relationship between the solution particle size and its impact on the overall effectiveness of the solution?
The smaller the particle size of a solution, the greater its overall effectiveness. Smaller particles increase surface area, allowing for better interaction with other substances and faster absorption or reaction rates.
What is the purpose of adding sodium hexametaphosphate solution to the soil suspension during particle-size analysis?
Sodium hexametaphosphate solution is added to soil suspension during particle-size analysis to disperse soil particles and prevent them from clumping together. This dispersion ensures accurate measurement of particle sizes and prevents errors that could occur if particles were to aggregate during analysis.
What information would you need to know about a sample of air before you classify the sample as a solution suspension or a colloid?
the size of its largest particle
What is the difference between particle size and crystallite size?
Particle size refers to the overall size of the individual particles in a material, while crystallite size specifically refers to the size of the crystalline regions within a material. Crystallite size is related to the arrangement of atoms within a material, while particle size is a more general measure of the physical dimensions of the particles.
What affects Bed load particle size?
what is bed load particle size
How do the mass and size of an alpha particle compare with mass and size of beta particle?
The mass and size of an alpha particle compare with the masa and size of beta particle in the sense that the alpha particle is significantly larger in both size and mass that the beta and gamma particles. This is why it is called the alpha particle.
What is the formula of mean particle size?
The formula for mean particle size is calculated by summing the individual particle sizes and dividing by the total number of particles. Mathematically, it is expressed as mean particle size = (Σ particle sizes) / total number of particles.
Is it true or false that particles have a fixed size?
False. Particles do not have a fixed size, as their size can vary depending on the type of particle and its environment. At the quantum level, particles can exhibit wave-particle duality, meaning they can behave both as particles and waves with differing characteristics.
How particle size affect solubility?
Particle size affects solubility. When particle size is small, the surface area per unit volume is larger, thus the solubility is increased.
