Q1.Is the path of light visible in a Suspension? Give reason.Q2. Differentiate between Suspension and Solution.Q3. Which among the following is/are suspension: Flour+ water, Salt +Water, Sand+water, Turmeric+water.Q4. Write three properties of Suspension.
Answers
Answer:
Answer: Flour+water, sand + water , turmeric +water. Explanation: They all are suspensions are they remain ...
Answer:
1.The particles in suspension scatter the beam of light making it clearly visible and this property is known as tyndall effect.
2.SOLUTIONS:
It is a homogeneous mixture.
the size of it's particles is less than 1 nm.
It does not show tyndall effect.
SUSPENSIONS:
Suspension is a heterogeneous mixture.
the size of particles is more than 100 nm.
It shows tyndall effect until the particles settle down at the bottom.
3. All are suspensions since they show tyndall effect and are insoluble in water so they don't mix and remain suspended. SALT+WATER is a true solution but until it settles down / dissolves in water completely it is called a suspension.
4. properties of suspension:
it is a heterogenous mixture.
the particles of a suspension can be seen with a naked eye.
it is unstable.
