Question
### Solubility Calculation of PbCO₃

**Objective:**
Calculate the solubility at 25 °C of PbCO₃ in pure water and in a 0.0120 M Pb(NO₃)₂ solution. 

You'll find \( K_{\text{sp}} \) data in the ALEKS Data tab.

**Instructions:**
Round both of your answers to 2 significant digits.

**Data Entry Fields:**
- **Solubility in pure water:** 
  \[ \boxed{\phantom{0}} \text{g/L} \]
  
- **Solubility in 0.0120 M Pb(NO₃)₂ solution:** 
  \[ \boxed{\phantom{0}} \text{g/L} \]

**Tools Provided:**
A graphical interface is available for entering and refreshing your answers:
- **Interface Icons:** 
  - Grid-like icons in various sizes.
  - A reset button and an undo button for corrections and adjustments.

Make sure to consult the \( K_{\text{sp}} \) data available in the ALEKS Data tab while performing these calculations. Ensure the results are rounded appropriately to maintain the accuracy necessary for educational purposes. 

### Summary

By calculating and comparing the solubility of PbCO₃ in pure water and in the presence of a common ion from Pb(NO₃)₂, students can understand the effects of ionic strength and common-ion effect on solubility.
