Formation Of A Salt

1. An ionic bond is the chemical bond between two ions with opposite charges that share characteristic of salts.

2. The electron configuration for Na is [Ne]3s1. The electron configuration for Na+ is [Ne] or 1s2 2s2 2p6. The electron configuration for Cl is 1s2 2s2 2p6 3s2 3p5 or [Ne] 3s2 3p5. The electron configuration for Cl- is [Ne] 3s2 3p6 .

3. Na+ resembles the noble gas Neon. Cl- resembles the noble gas Argon.

4. Na+Cl

Mass of the empty beaker 98.9 g

Mass of the beaker + NaHCO3 99.4 g

Mass of the NaHCO3 0.5 g

Mass of the beaker + NaCl 99.6 g

Mass of the NaCl 0.7 g

Post Lab Questions

1. As I added the hydrochloric acid the solution turned a pale yellow color making the acid neutral.

2. Carbon dioxide was released during the chemical reaction.

3. It is evident that the sodium hydrogen carbonate underwent a chemical change because the beaker was warm and gaseous bubbles formed.

4. The resulting white powder in the beaker was crystallized during the reaction, forming the compound salt.

Analyze and Conclude

1. The product was different from the reactant because they all had a unique texture, color and also a different physical state.

2. To make sure that the white powder was all sodium chloride you would need to add more of hydrochloric
