Why do colloids show the Tyndall effect?
In true solutions the solute dissolves completely in the solvent at the molecular level, meaning that the solute particles are present at their molecular size - well below the size of a particle required to exhibit light scattering dispersion (the Tyndall effect).
Is there a way to measure particle size?
Yes, there are a number of different methods and instruments that can measure particle size. The method of testing and type of instrumentation required is partly dependent on the form of the sample to be measured for example; sprays, droplets, powders, suspensions.
What is the formula of mean particle size?
Mean particle size=0.94*Lambda/(FWHM*cos(theta)
What is the relationship between porosity bulk density and particle density?
If you were to graph particle size and porosity, it would be a constant slope (horizontal line).Porosity is not affected by particle size.
What is the particle size of gneiss?
1cm
A solution shows a Tyndall effect or soap shows Tyndall effect?
soapy water will give a tyndall effect as it is a colloidal in nature.
Can you give me a sentence with the word tyndall effect?
The Tyndall effect is used commercially to determine the size and density of particles in aerosols.

What is the effect of particle size?
anung sagot?
Is salt solution shows Tyndall effect?
Yes, it does because tyndall effect is caused by scattering of light by small particles in colloidal solutions in transparent medium. (colloid means the mixture of particles less than size of particles in suspension)
Two factors that effect the size of glaciers?
Glacier size is dependent on snowfall and temperature.
What is the effect of particle size on the rate of dissulution of a solute?
Smaller the particle, faster the dissolution. By the way, you spelled dissolution incorrectly.
What is a tyndall effect in chemistry?
The phenomenon of scattering of light by colloidal particles as a result of which the path of the beam becomes visible visible is called Tyndall effect. Causes : The colloidal particles first absorb the incident light and then part of it gets scattered by them. Since the intensity of the scattered light is at right angles to the plane of the incident light, the part becomes visible only when seen in that direction.
What is the difference between particle size and crystallite size?
crystallite is the average size of the particle whereas the particle size denotes the individual size of the particle.
Is there a way to measure particle size?

What is a homogeneous mixture is it soot in water alcohol in water or oil in water?
Soot in water scatters light, demonstrating the Tyndall effect. It is heterogeneous.Alcohol dissolves completely in water and forms a homogeneous mixture.Oil does not dissolve in water to any appreciable extent but if the droplet size is small enough it will form an emulsion. Emulsions demonstrate the Tyndall effect and so, are classified as heterogeneous.
Explain how temperature pressure particle size agitation effect solubility?
The more a solution is agitated, the faster the rate of the solution The smaller the particle size, the faster it will dissolve The higher the temperature, the faster rate of dissolving
