Water Investigation- Battery-Wire Lab

-----------------------------------------------------------------------------------------------------------------------------------------------------------------

- Water Investigation -

This lab consisted of plugging in a charged battery with two wires- one red, one black -and charging them to two beakers with water molecules inside. Once we connected the battery to the wires, we immediately saw a reaction.

> This lab relates to the copper pipe corrosion problem in San Francisco by having the battery (In the water investigation lab) serve as the copper in the original lab. The copper separated the silver nitrate to two different atoms, causing the after effects to occur- similar to the water investigation with the battery separating the water molecules to sets of hydrogen's and oxygen's.

Based on the water investigation experiment, I can conclude that water molecules (H2O) did not come from the battery itself, even though it was the battery that caused the reaction. The water molecules that were initially in the beaker before the battery gave off its charge. After, the water molecules separated and went to one of the two tubes. It is clear that the battery did not give off any water molecules during the experiment because there were never any water molecules before. The battery only gave off its charge which caused the water molecules in the beaker to separate. Thus, creating a reaction to both of the individual tubes. Both tubes- one with a red wire and one with a black wire -resulted with different observations. The red wired tube attracted a lot of bubbles which eventually concealed most of the wire. The black wire showed a lot of bubbles but they were leaving the black wire and were heading to the top of the tube. With these observations, the gas splint tests made me make predictions in which i needed to find what gas was in each tube. When i put the lit splint over each tube they both gave different results. The red wire tube got a bit brighter and then it became immediately extinguished. The black wire tube gave off a “pop” noise. With these reactions, i concluded that Oxygen was in the red tube wire and Hydrogen was in the black tube wire. My evidence here clearly shows that my claim is valid because I had information prior to the packet we were given regarding the after effects with oxygen and hydrogen. The final results for each tube matched the descriptions on the packet. When the tube gives off a pop sound, hydrogen was present due to it being an explosive gas. Oxygen increases any flame due to it being one of the initial elements for a fire. This demonstrates that hydrogen and oxygen were initially together (water molecule) but were separated after the battery was plugged into the wires. This caused the oxygen's to go in one side(tube) and the hydrogen's to go in the other. Giving off the effects we observed.
