Please fill out the entire chart below and show your work for part b... I'm so lost! Part B is the part I need the most help with. Thank you!
- Copy and complete the following table in your laboratory
notebook.
- In the first column (pH), predict whether an aqueous solution of the compound would be acidic (a), basic (b) or neutral (n). Refer to your lab manual, pp. 186-187.
- In the corresponding cells in the table write “NR” for no reaction, meaning the two solutions would not react to form a precipitate, or indicate what reaction would occur (e.g. “blue ppt” for blue precipitate, “white ppt” for white precipitate, “bubbles” for gases being formed, etc.). Refer to your lab manual, pp. 188-189.

Part 1- Could someone tell me which of these are soluble and
insoluable.
Part 2- How do you write a net ionic equation for the
precipitate?
Briefly review the reagents involved in the procedures for test tubes #2 and 3 (see pp. 8-3 and 8-4 in your lab manual.). Each test tube started with a solution containing the sodium or potassium salt of each anion. In test tube 2, a solution of silver nitrate (AgNO3) was added. In test tube...

Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...
