Hypothesis: That the neutralization reaction between the bicarbonate of soda and the vinegar will produce a gas, which build up enough pressure to launch the bottle rocket.
Materials: Vinegar, bicarbonate of soda (NaHCO3)
Equipment: Plastic Bottle, Wooden Block, Nail, Cork, Duct Tape.
Method:
1. Nailed a cork to plank of wood as a base for the rocket.
2. Wrapped tape around cork so that it fitted the neck of the bottle.
3. Put two spatulas of baking soda into a paper towel, and rolled it so that it encased the powder.
4. Filled bottle ¼ of the way up with vinegar.
5. Added package of bicarb soda into bottle, then quickly turned base over so that the cork faced the opening of …show more content…
The carbon dioxide gas which would have been produced when the baking soda had reacted with the vinegar, may have built up pressure against the cork at the opening of the bottle. This allowed the rocket to launch, as the pressure pushed the bottle away from the base and up into the air. This happens because the substance which is an alkaline (in this case the bicarbonate of soda), and a substance which is acidic (the vinegar) can neutralize each other (described …show more content…
If an atom has missing electrons, it will have a positive charge, and if has more electrons than protons, it will be negatively charged, this often happens when atoms transfer electrons.
The transfer of electrons happens when two atoms bond. For example, when chlorine, which has 17 electrons (one missing to make a full outer shell of 8) bonds with sodium, which has one extra electron, because these atoms are the closest to having full valence (outermost) shells, they are the most reactive. So when sodium gives its extra electron to chlorine when the bond takes place, it now has a positive charge, as there are more protons than electrons. Chlorine is now a negatively charged ion, as it has more electrons than protons.
Acids are positively charged, and the more positive hydrogen atoms they have in them, the more acidic they are. Whereas when bases contain more negatively charged hydroxide, and depending how much there is, can make a substance more alkaline. The two cancel each other out, as such, if they are the same level away from pH of 7 (refer to introduction), and make a neutral substance(s), because they have opposite
