the word equation for sodium and water is:
sodium+water-->sodium hydroxide+hydrogen
sodium and chlorine: sodium+chlorine-->sodium chloride
what will the equation for aqueous chlorine with aqueous potassium iodide be?
To determine the word equation for the reaction between aqueous chlorine and aqueous potassium iodide, we need to understand the reaction between chlorine and iodide ions.
First, let's break down the components involved:
Aqueous chlorine: This refers to chlorine gas (Cl₂) dissolved in water (H₂O), which dissociates into chlorine ions (Cl⁻) in the aqueous solution.
Aqueous potassium iodide: This is potassium iodide (KI) dissolved in water (H₂O), which dissociates into potassium ions (K⁺) and iodide ions (I⁻) in the aqueous solution.
With this information, we can write the reaction equation.
The reaction between chlorine and iodide ions can be represented as follows:
Chlorine (Cl₂) + Iodide ions (I⁻) → Iodine (I₂) + Chloride ions (Cl⁻)
Now, let's incorporate the fact that chlorine and iodide ions are in an aqueous solution, indicating they are dissolved in water. We can represent this by adding (aq) after the chemical formulas.
So, the word equation for the reaction between aqueous chlorine and aqueous potassium iodide can be written as:
Aqueous chlorine + Aqueous potassium iodide → Iodine (solid) + Aqueous chloride
In chemical symbol notation, the equation becomes:
Cl₂(aq) + 2KI(aq) → I₂(s) + 2KCl(aq)
