Week 22: Constant Ratios in Chemistry.

In the past week, our Chemistry class has focused upoon a certain  chemical ratios that are constant undrr different situtations. This means that Water will ALWAYS be 2 Hydrogen molecules and 1 Oxygen atom because of Constant ratios. This means that if a certain chemical is made up of these ammount of atoms, theratio of one atom to another will not change, ever. Watter can only be 2 hydrogen atoms and 1 oxygen atoms, if the ratio is not 2:1 then it is not chemically water. H2O2 is in fact Hydrogen Peroxide


We proved the existance of thses constant when we  performed electrolysis with our own mini kits, similar to the illustration above, but without the ballons to collect gas, we sinply had test tubes. After pouring water and an anti corrosion agent ( that stung bad when it was upon my hands) we began to  crank the Genacon and send positive charges to one pole and negative charges to the other pole ( we unfortunately did not know which pole was which, but the above illustration can shed) some light upon which pole is which,) and  we began to ( slowly) sepertate the oxygen and hydrogen out of the wateer and into separate  test tubes. We ended up with 1 ml of Hydrogen and 1/2 ml of Oxygen, while the ammount of gas our group had collected was small, the ratio of 2:1 was the same among all the groupsi n the classroom.


We further proved that ther was 2 times more hydrogen   than oxygen when found out how many moles per gram of hydrogen and water there were, finding the ratio was still 2 to 1. While the mass of Oxygen dwarfed Hydrogen,  Hydrogen was still 2x more abundant when collected from electrolysis proving that there is a constant ratio for chemical substnaces NO MATTER WHAT. If it's  H2O its water, and nothing else.
