Hey there!
The answer you are looking for
is polarity
Hydrogen (even though has one electron is positive)
Oxygen is negative (needs two to complete)
due to the oxygen hydrogen now experiences electronegativity
the need to want to bond
but ordinarily
Hydrogen wants to lose
but it is with this special scenario where if a compound like salt is in place
the Hydrogen dissolves the Chlorine and Oxygen to the Sodium
So its all polarity
