AIIMS 2018 Chemistry Oxides of Nitrogen MCQ Question
Which of the following statement is incorrect?
On prolonged dialysis colloid becomes stable.
in excess KI forms negative colloid.
in excess KI forms positive colloid.
Medicines work best in colloidal form because of greater surface area
Correct Answer
Detailed Explanation
In the solid state, N₂O₅ exists as a molecular compound that can be represented as [NO₂⁺][NO₃⁻], indicating the presence of nitronium ions (NO₂⁺) and nitrate ions (NO₃⁻) due to its ionic character in the solid phase. This structure arises from the dimerization of nitrogen pentoxide, where the molecular interactions lead to the formation of these ionic species. Other options are not applicable as they do not provide relevant information or alternatives regarding the nature of N₂O₅ in solid form, making them irrelevant to the question. Understanding this ionic representation helps clarify the behavior of N₂O₅ in different states and its reactivity in various chemical processes.
