For our first lab we are testing water to see how much gas it has inside. We hooked up wires into the tubes of water and then we connected those wires to the tubes of water and ran current through them. Once the electrical current was running through it then we can see that there was gas bubble forming on the tubes. Soon after the tops of the tubes have gas. We tested the gas to see what it was by using a match lit on fire.
CER- The water molecules contain Hydrogen and Oxygen gasses. After doing the experiment we observed that as the electricity goes through the wires the bubbles started to float. One tube had more gas than the other because the H2O atom has 2 hydrogen atoms and one oxygen atom. When we burnt the gas we got two different reactions. In the one that had more gas we heard a popping sound which pertains to the hydrogen burning. In the one that had less gas we had the matchstick glow brighter due to the extra oxygen aiding the flame. In this experiment we proved how the H2O molecule has both hydrogen and oxygen gas.
Connection to our Big Problem- In this experiment we found how the electric current passes through the wire and causes bonds on atoms to split. This procedure is very helpful because we can use it to prove that a chemical reaction occurred. In our pipe problem we can use this battery to split the bond between the nitrate and the copper.
