When an acid is dissolved in water (H2O), what element separates from the acid to bond with water to create H3O+?

1. Cl

2. Na

3. H

4. O

Answer: 3 H

An acid consists of a hydrogen {positive radical} and a halogen or negative radical. When it is dissolved in water, the ionic bond is broken and ions are separated. The free H + radical gets attracted to Hydrogen of water H2O and so it forms H3O+. The ionic bond gets weaker in water as electromagnetic forces are weak in water as water is dielectric medium.

I think the answer is number 4-O.

I’m not sure tho ...
