Romashka [77]

Answer:

The correct answer is d. hydronium ion.

Explanation:

Hydronium ion is a positively charged molecule that has three hydrogen atom bonded with an oxygen atom. Hydronium ion is formed when the water molecule gains an extra H+ ion from somewhere.  

This H+ ion easily form bonds with one of the lone pairs present on the water molecules. H2O is also a polar molecule and has a partially positive charge due to which the extra H+ ions get attracted to the negative pole of water and make hydronium ion. Therefore the correct answer is d.
