Question
The element which can from an acidic oxide should be the one whose atomic number is:
(a) 6
(b) 16
(c) 12
(d) 19
Solution
(b) 16.
The element which can form an acidic oxide should be the one with atomic number 16. Sulphur has an atomic number of 16 and sulphur oxide is acidic.
Note: Option (a) 6: carbon also forms an acidic oxide but the acidic strength of the oxides of sulphur (16) is greater than that of carbon (6).
Is there an error in this question or solution?
