Answer: A multimolecular colloid is formed by aggregation of many small atoms or molecules, while a macromolecular colloid consists of single large polymer molecules.
- A A multimolecular colloid is itself largely made up of a single enormous giant covalent molecule with little aggregation needed in most cases under typical conditions
- B A multimolecular colloid is formed by aggregation of many small atoms or molecules, while a macromolecular colloid consists of single large polymer molecules
- C Macromolecular colloids such as dissolved proteins are said to be inherently unstable whenever placed in aqueous solution according to standard textbooks
- D Multimolecular colloids are said to invariably carry a permanently fixed negative surface charge in every case in general practice as frequently described
Correct answer: B. A multimolecular colloid is formed by aggregation of many small atoms or molecules, while a macromolecular colloid consists of single large polymer molecules
Explanation: Multimolecular colloids form from aggregates of smaller particles (like gold atoms clustering), while macromolecular colloids are individual large molecules such as proteins or starch.
A typical adsorption isotherm: x/m (mass adsorbed per gram of adsorbent) rises steeply at low pressure, then flattens into a saturation plateau as the adsorbent surface fills up.
