AgNO₃ = Ag⁺ + NO₃⁻

Answer 2

Identifying and Describing Four Salts

To help you identify and dissociate four salts, let's take a look at the chemical formulas and dissociation reactions for each salt.

1. Sodium Chloride (NaCl) - Sodium chloride dissociates into sodium ions (Na⁺) and chloride ions (Cl⁻) in water. - The dissociation reaction is: ``` NaCl → Na⁺ + Cl⁻ ```

2. Sodium Bicarbonate (NaHCO3) - Sodium bicarbonate dissociates into sodium ions (Na⁺), bicarbonate ions (HCO3⁻), and hydrogen ions (H⁺) in water. - The dissociation reactions are: ``` NaHCO3 → Na⁺ + HCO3⁻ HCO3⁻ → H⁺ + CO3²⁻ ```

3. Potassium Hydroxide (KOH) - Potassium hydroxide dissociates into potassium ions (K⁺) and hydroxide ions (OH⁻) in water. - The dissociation reaction is: ``` KOH → K⁺ + OH⁻ ```

4. Calcium Carbonate (CaCO3) - Calcium carbonate does not dissociate into ions in water as readily as the other salts mentioned above. However, it can undergo a dissociation reaction in the presence of an acid. - The dissociation reaction with hydrochloric acid (HCl) is: ``` CaCO3 + 2HCl → CaCl2 + H2O + CO2 ```

These are the chemical formulas and dissociation reactions for the four salts you requested.
