Capitolo 4, Problema 18b
Specify what ions are present upon dissolving each of the following substances in water: (b) K2CO3
Guida verificata passo dopo passo1
Identify the formula given and recognize it as a salt. In this case, the formula is K2CO3, which is potassium carbonate.
Understand that dissolving an ionic compound in water typically results in the compound dissociating into its constituent ions.
Determine the ions that make up potassium carbonate. Potassium carbonate consists of potassium ions (K+) and carbonate ions (CO32-).
Recognize that each formula unit of K2CO3 dissociates into two potassium ions and one carbonate ion in solution.
Conclude that when K2CO3 is dissolved in water, the ions present in the solution are K+ and CO32-.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Dissociation of Ionic Compounds
When ionic compounds like K<sub>2</sub>CO<sub>3</sub> dissolve in water, they dissociate into their constituent ions. This process occurs because the polar water molecules surround and separate the individual ions, allowing them to disperse throughout the solution.

Ionic Compounds Naming
Ionic Composition of Potassium Carbonate
Potassium carbonate (K<sub>2</sub>CO<sub>3</sub>) consists of potassium ions (K<sup>+</sup>) and carbonate ions (CO<sub>3</sub><sup>2-</sup>). Each formula unit of K<sub>2</sub>CO<sub>3</sub> produces two potassium ions and one carbonate ion when it dissolves in water.

Charge Balance in Solutions
In a solution, the total positive charge must balance the total negative charge. For K<sub>2</sub>CO<sub>3</sub>, the two K<sup>+</sup> ions contribute a total charge of +2, which balances the -2 charge from the single CO<sub>3</sub><sup>2-</sup> ion, ensuring electrical neutrality in the solution.
