What is the correct chemical formula for the ions formed when acids dissolve in water?H+OH+OH–H–

When acids dissolve in water, they dissociate to form ions. The primary ion that results from this dissociation is the hydrogen ion (H⁺).

1. Understanding Acid Dissociation: Most acids will release H⁺ ions when they dissolve in water. This H⁺ ion is often associated with water molecules to form hydronium ions (H₃O⁺).

2. Role of Hydroxide Ions: The other component here is hydroxide ions (OH⁻), which can form as a result of water dissociation but is not produced directly from the dissociation of acids.

3. Ion Formation Summary: Thus, for an acid like hydrochloric acid (HCl), it dissociates in water as follows:

   $\text{HCl} \rightarrow \text{H}^+ + \text{Cl}^-$

4. Key Ion: The primary ions formed are H⁺ (or H₃O⁺ when water is involved) and the corresponding counter ions such as Cl⁻. Hydroxide ions are more commonly associated with bases instead of acids.

Final Answer

The correct ions formed when acids dissolve in water are primarily H⁺ and counter ions specific to the acid (e.g., Cl⁻ for HCl). Hydroxide ions (OH⁻) are typically associated with bases rather than acids.
