Objective: To split water into hydrogen gas and oxygen gas using an electric current
Hypothesis: Because there are 2 hydrogen atoms for every oxygen atom we should get twice as mush gas as oxygen gas.
Materials: 2 test tubes, .jar, baking soda, wires (22 gauge), water, 9 volt battery, duct tape
1 Cut wire into 2 pieces and strip wire of both ends fold end of wire and tuck into test tube secure with duct tape and repeat.
2 dissolve baking soda into warm water pour.
3 pour baking soda into test tubes also put baking water into .jar.
4 invert test tubes into the water filled beaker ,then tape to side of .jar.
5 attach wire to battery.
6 to stop the reaction disconnect the wires from the battery.
7 Determine which eletrode is releasing hyrogen and which is releasing oxygen.
Our Data Collected
1 The wires started bubbling and look liked there was air pressure building up inside the test tubes
2 We observed one test tube was displacing water two times as fast as the other.
3 And we can assume the hydrogen is displacing two times more water then the oxgen becase the makeup of water is h2o, or two parts hyrodgen to one part oxygen.
