Homework Answers
1. AgNO3 is well soluble in water (256 g/100 mL at 25 °C).
2. NaCl is clearly soluble in water.
3. AgCl is not soluble in water or partially soluble at minute concentrations, becuase the solubility product (Ksp) of AgCl is less.
4. Na2CO3 is clearly soluble in water.
5. Ag2CO3 is poorly soluble in water or almost insoluble.
6. MgSO4 is soluble in water.
7. Ag2SO4 insoluble in water.

I need helppp with my AP chem lab
Purpose: To calculate the amount of AgNO3 present in an unknown solution of water through the process of gravimetric analysis with NaCl. Background: Have you ever had difficulty lathering soap or find that the scum in your shower constantly needs to be removed? These are signs of “hard water.” Soap does not lather well in hard water because metal ions, such as Ca2+, form precipitates, creating “soap scum.” A precipitate is an insoluble compound that forms when soluble ions in...

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
