Oxide is soluble in water. The aqueous solution of oxide does not change color of red litmus solution but reacts with an aqueous solution of sodium hydroxide. This indicates that the oxide is acidic oxide. Hence, the options B and D are correct answers.
Correct option is
B
Phosporous
D
Sulphur
The highly reactive element is either S or P. It reacts with oxygen of air even at room temperature to give an oxide .
S+O2→SO2
P4+5O2→P4O10
Oxide is soluble in water. The aqueous solution of oxide does not change color of red litmus solution but reacts with an aqueous solution of sodium hydroxide. This indicates that the oxide is acidic oxide. Hence, the options B and D are correct answers.
