A Mixture of sulphur and carbon disulphide is
(a) Homogenous and show tyndall effect
(b) Heterogeneous and show tyndall effect
(c) Homogenous and does not show tyndall effect
(d) Heterogeneous and does not show tyndall effect
A mixture of sulphur and carbon disulphide is an example of colloid. it does not form uniform composition. uniform composition mean, a mixture of uniform composition is one in which molecules of all the components are arrange uniformly throughout the mixture. it is not possible to recognizes them. but in case of mixture of sulphur and carbon disulphide, it does not form uniform composition.
Now, if we talk about properties of this mixture, properties of the mixture are totally different throughout the solution. it mean, properties are different of both the items (sulphur and carbon disulphide). Due to this reason, we can say that this mixture form heterogeneous colloid and it show tyndall effect.
It show the tyndall effect, the main reason is that, sulphur remains suspended in water. it mean, sulphur (solid) is easily spread throughout the liquid (carbon disulphide – it is colourless volatile liquid) without the dissolving in it. after spreading of sulphur (solid) in liquid, they settles down slowly as a bottom layer in carbon disulphide. so, the suspended particles can show this tyndall effect.
If we talk about tyndall effect. The scattering of light by colloidal particle. due to scattering of light we are sometimes able to see the path of light, this phenomenon is called tyndall effect. Scattering of light is depends upon size of particles. If the size of particles is large then it gives better scattering of light but if the size of particles is small then it gives poor scattering. the main reason is that, the large particle size scatter all colours whereas small particle size scatter only blue colour.
Tyndall effect is the special type phenomenon where the light is scattered by colloid (sulphur + carbon disulphide). but sometimes, the source of light is not completely pass through by individual particle of colloid. it is absolutely true and it is possible when the individual particles of colloid when keep in front of light source. tyndall effect activities is not show (occur) in individual particle of colloid. because, the main reason is that, do not allow the source of light or path of light to completely pass through it. it will not visible source of light or path of light in individuals colloid.
Tyndall effect depend upon following terms, such as
- Depend upon proper scattering of light.
- Depend upon particle size in colloidal solution.
- Depend upon properly scattered for all colour.
These are the basic reson for the mixture of sulphur and carbon disulphide is heterogeneous and show tyndall effect. it mean if scattering of light (scattered all colour) is proper then show tyndall effect and then it is visible to show source of light in colloidal solution. Otherwise it is not visible and not show tyndall effect (source of light) in colloidal solution.
According to above information, we can say that the correct answer is option (b).
- It is a form homogenous colloid but actually it is a heterogeneous colloid.
- Particle size range from 1 to 1000 mm.
- Separation of particle from solution is difficult.
- It is very difficult of separation of particle from colloid by filtration.
- Light scatter (show tyndall effect).
- Not visible through the naked eye.
A Mixture of Sulphur and Carbon Disulphide is – homogeneous or heterogeneous?
A mixture of sulphur and carbon disulphide is, a homogeneous but they are actually heterogeneous. because a colloid is a mixture in which solid particles are easily spread throughout the liquid without dissolving in it. in othe words, one substance is distressed in another substance. According to this, the best examples of colloid is milk.
You know that, milk is one type of colloid solution, milk show Tyndall effect. When a source of light is directed, at a glass of milk, the source of light is clearly scattered. due to this, they show activities of tyndall effect. this is the great examples for tyndall effect.
Tyndall effect depend upon scattering of light, if source of light is scattered properly, it show tyndall effect otherwise they dont show tyndall effect. for example, “glass of water” When a source of light is directed, at a glass of water, the source of light is not scattered. Due to this, we will not able to see the path of light in a water solution. due to this reason, they can’t show tyndall effect.
Scattered of light also depend upon particles size of colloid. big particles are scattered all colour where as small particles scatter only blue colour. In this mixture of solution has big particle size and scattered properly. and show tyndall effect.
therefore, we can say that, a mixture of sulphur and carbon disulphide is heterogeneous. and show tyndall effect.
A mixture of sulfur and carbon disulfide can have various properties depending on the proportions of the two substances and the conditions under which they are mixed.
Let’s explore a few possibilities:
- Homogeneous Solution: If sulfur and carbon disulfide are mixed in the right proportions and conditions, they can form a homogeneous solution. In this case, the sulfur would dissolve in the carbon disulfide to create a single phase solution.
- Suspension: If the proportion of sulfur is relatively high compared to carbon disulfide, the sulfur may not fully dissolve and instead form a suspension. This means that solid sulfur particles would be dispersed throughout the liquid carbon disulfide, giving it a cloudy appearance.
- Separate Phases: If the proportion of sulfur is significantly higher than the solubility limit in carbon disulfide, the two substances may separate into distinct phases. Sulfur would precipitate out as a solid, and a layer of sulfur would form at the bottom of the container, while the remaining carbon disulfide would be present as a liquid layer on top.
The specific properties and behavior of the mixture would depend on the concentrations of sulfur and carbon disulfide, temperature, pressure, and other factors.
It is important to note that both sulfur and carbon disulfide are hazardous substances, so handling them should be done with caution and following appropriate safety protocols.
Explain the Separation technique of the mixture of carbon and sulphur?
Sepration techniques – the mixture of carbon and sulphur is separated by using a solution of carbon disulphide.
You know that, sulphur is soluble in water whereas carbon is insoluble in water. therefore, sulphur is easily dissolve in solution whereas carbon is undissolved.
Undissolved carbon will remove by applying filtration methods whereas sulphur obtain by using evaporation methods. and in other words, undissolved carbon is separated by filtration technique whereas the dissolved sulphur can be separated by using evaporation technique.
Suspended solids refers to small solid particles which remain in suspension in water as a colloid or due to motion of the water. suspended solids can be removed by sedimentation because of their comparatively large size. It is used as one indicator of water quality.
Removal of suspended solids
this is generally achieved through the use of and water filters. By eliminating most of the suspended solids in a water supply, the significant water is usually rendered close to drinking quality.
