The dispersed phase in colloidal iron (III) hydroxide and colloidal gold is positively and negatively charged respectively.
When two solutions are mixed, they will affect mutual coagulation. This is because the charge on one sol is neutralized by the opposite charge on the other sol. Hence, statement A is not correct.

Explanation:

Mixing the sols has no effect:
- When colloidal iron (III) hydroxide and colloidal gold are mixed, they do not coagulate or show any significant interaction.
- This statement is correct because mixing the sols typically does not have any effect on their individual stability or properties.

Coagulation by electrophoresis:
- Both colloidal iron (III) hydroxide and colloidal gold can be coagulated by electrophoresis, as the positively and negatively charged particles can be brought together by the applied electric field, leading to coagulation.

Magnesium chloride and sodium sulphate solutions:
- Magnesium chloride solution can coagulate the gold sol more readily than the iron (III) hydroxide sol due to specific interactions between the ions in the solution and the charged particles in the sols.
- Sodium sulphate solution can cause coagulation in both sols through different mechanisms, such as neutralization of charges or the formation of complexes with the colloidal particles.
In conclusion, the correct statement among the given options is that mixing the sols has no effect, as it is typically true for most colloidal systems unless specific interactions or conditions are present to induce coagulation.

Similar Class 12 Doubts

Read the passage given below and answer the following questions:The amount of moisture that leather adsorbs or loses is determined by temperature, relative humidity, degree of porosity, and the size of the pores. Moisture has great practical significance because its amount affects the durability of leather, and in articles such as shoes, gloves and other garments, the comfort of the wearer. High moisture content accelerates deterioration and promotes mildew action. On the other hand, a minimum amount of moisture is required to keep leather properly lubricated and thus prevent cracking. The study indicates that adsorption of moisture by leather is a multi- molecular process and is accompanied by low enthalpies of adsorption. Further at 75-percent relative humidity, the adsorption is a function of surface area alone. Untanned hide and chrome- tanned leathers have the largest surface areas. The leathers tanned with vegetable tanning materials have smaller surface areas since they are composed of less hide substance and the capillaries are reduced to smaller diameters, in some cases probably completely filled by tanning materials. This process of tanning occurs due to mutual coagulation of positively charged hide with negatively charged tanning material. The result of the study indicated that untanned hide and chrome-tanned leather absorb the most water vapour.In these questions a statement of Assertion followed by a statement of Reason is given. Choose the correct answer out of the following choices.Assertion (
