A solution containing a mixture of metal cations was treated as outlined. 1. Dilute HCl was added and a precipitate formed. The precipitate was filtered off. 2. H,S was bubbled through the acidic solution. Again, a precipitate formed and was filtered off. 3. The pH was raised to about 9 and H,S was again bubbled through the solution. No precipitate formed. 4. Finally, sodium carbonate was added. A precipitate formed and was filtered off. What can be said about the...

9 Name IONIC and COVALENT BONDING LAB ACTIVITY, PROCEDURE and REPORT SHEET BIG IDEAS: ectron configurations determine how atoms combine to form chemical bonds. 2. According to the valence bond theory, the outermost electrons of atoms, the valence electrons, are the ones involved in bonding. 3. Atoms of elements can LOSE, GAIN, or SHARE electrons so that each atom involved achieves a noble gas electron configuration. This is known as the OCTET RULE 4. When atoms lose or gain electrons,...

1. Write the chemical formulas for all the barium salts that can be formed in Part 1 Part 1A: Solubility of barium salts under neutral conditions 1. Using a clean disposable pipet, transfer 1 mL of Co-anion solution to a clean test tube and label the test as "Co?- neutral". Repeat this for the remaining anion solutions S0?-?,P03-?, NO3",C1-7,7- 'so that you will have six test tubes with six unique anion solutions. Use a different pipet for each anion solution,...
