Given the equation:

HCl(g) + H2O(l)--> X(aq) + Cl--(aq)

Which ion is represented by X?

(1) hydroxide (3) hypochlorite

(2) hydronium (4) perchlorate

Verified Answer :

IwAsSoMeGuY

X will be hydronium (H3O)

Answer: The correct answer is Option 2.

Explanation:

For the given options:

Option 1: Hydroxide ion

The chemical formula for this ion is \(OH^-\)

Option 2: Hydronium ion

The chemical formula for this ion is \(H_3O^+\)

Option 3: Hypochlorite ion

The chemical formula for this ion is \(ClO^-\)

Option 4: Perchlorate ion

The chemical formula for this ion is \(ClO_4^-\)

For the given chemical reaction:

\(HCl(g)+H_2O(l)\rightarrow H_3O^+(aq.)+Cl-(aq.)\)

The ion represented by X is hydronium ion.

Hence, the correct answer is Option 2.
