For each of the following compounds, decide whether the compound's solubility in aqueous solution changes with pH. If the solubility does change, pick the pH at which you'd expect the highest solubility. You'll find sp data in the ALEKS Data tab. highest solubility Does solubility change with compound pH? pH = 6 pH = 7 pH = 8 yes CaCl₂ no yes az (PO4)₂ no Iyes PbCl₂ no ? Ca₂ X

Ca3(PO4) ksp =2.07x10^-33

PbCl2 ksp= 1.70x10^-5

CaCl2 ksp= 1.63x10^3

### Solubility and pH Dependence of Selected Compounds For each of the following compounds, determine whether the compound's solubility in aqueous solution changes with pH. If the solubility does change, select the pH at which you would expect the highest solubility. You will find \( K_{sp} \) data in the ALEKS Data tab. #### Table: Solubility Dependence on pH | Compound | Does solubility change with pH? | Highest Solubility | |------------------|:--------------------------------:|--------------------| | CaCl₂ | yes | ( ) pH = 6 | | | no | ( ) pH = 7 | | | | ( ) pH = 8 | | Ca₃(PO₄)₂ | yes | ( ) pH = 6 | | | no | ( ) pH = 7 | | | | ( ) pH = 8 | | PbCl₂ | yes | ( ) pH = 6 | | | no | ( ) pH = 7 | | | | ( ) pH = 8 | #### Instructions: 1. For each compound listed in the left column, decide whether its solubility changes with pH by selecting either "yes" or "no" in the "Does solubility change with pH?" column. 2. If you select "yes," then specify the pH at which you would expect the highest solubility by marking one of the options (pH = 6, pH = 7, or pH = 8) under "Highest Solubility." #### Example: - For the compound **CaCl₂**, the solubility does change with pH, so you would select "yes." Then, mark the appropriate pH value where the highest solubility is expected. This exercise helps in understanding how different compounds react to pH changes, an important concept in chemistry that influences various applications such as pharmaceuticals, environmental science, and even culinary arts. **Note:** The pink circle in the image indicates that the "yes" option for the compound **CaCl₂** has been selected.
