To begin the lab, a calculation was done with the given variables of 60.0mL and 0.5000M for a NaOH solution. Looking for grams, the result of 1.20g was found. With this number, the lab activities were to be initiated. All lab participants in the group all retrieved and wore lab goggles that were adjusted and made proper for the lab. The proper apparatus was then collected from their appropriate cabinets and containers. As the lab was conducted during lunch, there was no competition between the choice of instruments and therefore the most sterile and in good condition were chosen. The method of collection is as follows, two graduated cylinders were gathered from cabinets from a lab member and the Erlenmeyer flask was acquired from another cabinet by another lab member. The buret itself was retrieved from another lab member while one person was …show more content…
Longer containers with smaller openings such as the graduated cylinders and buret where wiped off by shoving paper towels down and rotating the glass while maintaining a hold on the towel. This method may have contributed to the percent error as this method could not wipe off every bit of liquid and there was some distilled water still at the bottom or near the bottom on the sides.
The NaOH solution was prepared first by filling a graduated cylinder with 60.0 mL of distilled water. The solute was then gathered delicately by quickly unscrewing the jar containing the NaOH; removing a small portion of it via metal scoop and relocating it to a glass. Shortly after, the lid is screwed back on to the jar as leaving it exposed to air molecules or water for too long may cause the whole jar to dissociate. If the initial portion was not enough to fulfill the 1.20g requirement, the process of unscrewing and deftly collecting the NaOH as to not inflict harm to the original jar of NaOH can be repeated
