Which of the following is not base according to Lux-Flood concept?
Correct answer: D. SiO2
- A. CaO
- B. MgO
- C. PbO
- D. SiO2
Explanation
This question tests the Lux-Flood concept in inorganic chemistry, critical for medical students understanding chemical behavior in physiological contexts. SiO2 is completely correct as it is not a base, unlike the basic oxides CaO, MgO, and PbO. Selecting other options risks misunderstanding acid-base chemistry.
