Answer 1

Answer:

Explanation:

The hydrogen ion in aqueous solution is no more than a proton, a bare nucleus. ... There is a lone pair of electrons on the oxygen giving it this shape. ... M. (1999) The nature of the hydrated excess proton in water;

Answer 2

The correct answer is option (1) H₉O₄⁺.

• The hydronium ion is an important factor when dealing with chemical reactions that occur in aqueous solutions.
• The hydronium ion or hydronium is the name given to the H₃O⁺cation, derived from the protonation of water.
• Its concentration relative to hydroxide is a direct measure of the pH of a solution.
• In aqueous solution the hydronium ion is further hydrated to five species like H₅O₂⁺, H₇O₃⁺and H₉O₄⁺.
