Based on the provided reference, pH has a specific effect on solubility, primarily through an inverse relationship: on increasing the pH, the solubility decreases and as we decrease the pH, the solubility increases.
The Relationship According to the Reference
The core finding presented in the reference is that solubility is inversely related to pH level according to the rule: "on increasing the pH, the solubility decreases and as we decrease the pH, the solubility increases".
This means:
- When the pH of a solution is lowered (becomes more acidic), the solubility of a substance increases.
- When the pH of a solution is raised (becomes more alkaline), the solubility of a substance decreases.
Context from the Reference
The reference states that this conclusion is inferred from a prior case where the solubility of a base increased. While the specific details of the base case aren't elaborated, the reference explicitly links the general rule about pH and solubility decreasing/increasing inversely to changes in pH to this example involving a base.
Summary of pH Effect on Solubility (Per Reference)
Here's a quick summary of the relationship described:
| Change in pH | Effect on Solubility (According to reference) |
|---|---|
| Increasing | Decreases |
| Decreasing | Increases |
It's important to note that the reference mentions other factors, such as temperature, also affect solubility, but the primary focus regarding pH is this inverse relationship.
