Questions & Step-by-Step Solutions
Which of the following statements about the common ion effect is true?
Step 1: Understand what a common ion is. A common ion is an ion that is present in a solution and is also part of a salt that is dissolving.
Step 2: Know what solubility means. Solubility is how much of a substance can dissolve in a liquid.
Step 3: Learn about the common ion effect. This effect occurs when a salt is added to a solution that already contains one of its ions.
Step 4: Realize that when a common ion is present, the solubility of the salt decreases. This means less of the salt will dissolve in the solution.
Step 5: Conclude that the statement about the common ion effect is true because the presence of a common ion reduces the amount of salt that can dissolve.
