The correct Answer is:
To determine the size of colloidal particles, we can categorize particles based on their size into three groups: true solutions, colloids, and suspensions. Here’s a step-by-step explanation: ### Step 1: Understand the Categories of Particle Size Particles can be classified into three categories based on their size: - **True Solution**: Particles are smaller than 10^-7 cm. - **Colloidal Particles**: Particles range from 10^-5 cm to 10^-7 cm. - **Suspensions**: Particles are larger than 10^-5 cm. ### Step 2: Identify the Size Range for Colloidal Particles From the classification: - The size of colloidal particles is specifically between 10^-5 cm and 10^-7 cm. ### Step 3: Conclusion Thus, the size of colloidal particles is variable and falls within the range of 10^-5 cm to 10^-7 cm. ### Final Answer The size of colloidal particles is between **10^-5 cm and 10^-7 cm**. ---

Correct the following statements by changing the underlined part of the sentence (Do not change the whole sentence) The size of the colloidal particles is of the order of ul("0.1 nm -1 nm.")

Assertion (A) An ordinary filter paper impregnated with collodion solution stops the flow of colloidal particles. Reason (R) Pore size of the filter paper becomes more than the size of colloidal particle. (a)Assertion and reason both are correct and the reason is correct explanation of assertion. (b)Assertion and reason both are correct but reason does not explain assertion. (c)Assertion is correct, but reason is incorrect. (d)Both assertion and reason are incorrect.

The size of the colloid particles is :

Assertion :- Filtration of colloidal particles is not possible by filter paper. Reason :- Size of colloidal particle is less than filter paper pores.

Assertion: Colloidal solution exhibit Tyndall effect while true solution particles. Reason: Because the size of the colloidal particles is large enough to scatter light as compared to size of the true solution particles.

Collidal solution is a heterogeneous solution which contains particle of intermediate size, i.e., (diameter between 1 and 1000 nm) colloidal is not a substance but it is a state of a substance which depends upon the molecular size. Colloidal solutions are intermediate between ture solution and suspensions. The size of the colloidal particles lies in the range
