Question

an element Y reacts with oxygen to form an oxide yo2 whose solution in water turns blue litmus red.is Y a metal or non metal ? give reason for your answer. it is urgent

Answer 1

Reaction :

Y + O₂ → YO₂ 

# It is given that it turns a blue litmus paper into red 
then literally it is an acid 

# As we know oxides of Non Metals are acidic in nature 
Then absolutely it is a Non Metal .

# Non-metallic oxides dissociate into their constituent ions in water, they give H+ ions in their aqueous solutions forming acids
For example:

CO₂ + H2O → H₂CO₃ .
