Step-by-step explanation:
Water is H20 which is 2 hydrogen atoms plus a oxygen atom
Oxygen (O²¯) is a anion, meaning it has a negative 2 charge (two extra electrons)
Hydrogen (H+) is a cation, it has one less electron in its atom
In water theres 2 H+ ions (2+ charge in total ) and 1 O²¯ ions (2- charge) , making the charges balance out and become neutral
Even though H20 is a neutral charged molecule, oxygen has higher electronegativity than hydrogen, making hydrogen comparatively positive to its oxygen atom
