Which one is the most acidic among these Cao, na2o, mgo, al2o3
Answers
Answer:
(C) Al2O3
Explanation:
higher the oxidation state of a metal higher is it's acidic nature. oxidation state is directly proportional to acidic nature.
Na2O oxidation state of Na = +1.
Mgo oxidation state of mg = +2.
Al2O3 oxidation state of Al = +3.
cao oxidation state of call = +2
Answer:
The Correct Answer would be Al₂O₃. Aluminium Oxide or Al₂O₃ is the most acidic compound among all.
Explanation:
An acidic oxide is an oxide that both produces an acidic solution upon addition to water, or acts as an acceptor of hydroxide ions efficiently functioning as a Lewis acid. Acidic oxides will commonly have a low pKa and can be inorganic or organic. A typically encountered acidic oxide, carbon dioxide produces an acidic solution (and the generation of carbonic acid) while dissolved.
The acidity of an oxide may be moderately assumed via way of means of its accompanying constituents. Less electronegative elements generally tend to shape fundamental oxides which include sodium oxide and magnesium oxide, while extra electronegative factors generally tend to provide acidic oxides as visible with carbon dioxide and phosphorus pentoxide. Some oxides like aluminium oxides are amphoteric.
