2. Lab One
Objective:
To see howlongit will take the oxygenandhydrogentoseparate fromeachotherwiththree
batteriesasthe energysource.
Introduction:
As a planetof pollutionstill beinganissue we are lookingfornew sourcesof energytohave our
vehiclesrunoff of tosave our planet.Hydrogenseemstobe the wayto go and thisexperimentwill
showus howwe can gather thisnatural resource.[Addmore]
Procedure:
▪ Step1:
o Readthe safetyguidelines
▪ Step2:
o Gatheredall of our instrumentsneeded
▪ SafetyGoggles
▪ Breaker
▪ Tongs
▪ Three batteries
▪ Three electricconnectors
▪ Distilledwater
▪ Sodiumsulfate
▪ Measuringteaspoons
▪ Two testtubes
▪ Timer
▪ Electrochemical Bath
▪ Step3:
o Cleanedoutall of our instrumentsthatwe are goingto use

3. Lab One
▪ Step4:
o Measuredthe sodiumsulfate
▪ Step5:
o Mixedthe distilledwaterandsodiumsulfate
▪ Step6:
o Placedthe combinationsolutionintothe Base &connectedtwoof the electric
connectorsto the base itself
▪ Step7:
o Usedthe tongsto fill the testtubesandplacedthemwithoutlettinganyof the
waterout of the testtubesontothe metal prongsinthe base that will release
the energythatwill allow the chemical change tooccur.
▪ Step8:
o Once that was completedconnectthe batteriestocreate a circuit
▪ Step9:
o Thenget the timerandonce three,six,nine,twelve,fifteen,eighteen,twenty-
one minutesyourecordwhere the Oxygenandthe Hydrogenlevelsineachtube
were torecordedhow fast theyare movingand gettingseparatingfromone
another
▪ Step10:
o Afterthe Hydrogeniscompletelyfilledtube two,tube one stopsbecause one
cannot continue withoutthe other,youcansetthe combustible hydrogenonce
youcomplete the experiment
Observation:
Afterwe connectedourpowersourcestostart separatingthe oxygenfromthe hydrogenthe
tubesstartedbubbling,butthe hydrogen(tubetwo) wasbubblingtwice asfastas tube one (oxygen).
Testtube two wasa milkywhite colorwhile testtube one wasclearatfirstthenstart turninga metallic
colorlike a rustycolor.To findouttesttube one start the oxidationprocessandthe waterstartedto get
rustyand once test tube twowas done gettingridof the liquidtesttube one stoppedmoving
altogether.
Results:
Testtube one had oxidationwaterinitwhile testtube twolostall colorandwas cleardue to the
hydrogenthatwas left.We evenwere able tolightthe hydrogenupata time too.The separation
processwassuccessful.
