Surface area is known to become beneficial to keeping organisms surviving it permits huge internal organs such as the intestinal tract to fit in a small area by being coiled and packed jointly tightly. This experiment looked if the area to volume ratio affected the speed of the chemical reaction. With this experiment, a film container was filled one-half full with water. In that case an Alka-Seltzer tablet was added, quickly covered which has a cap and was observed until the film cap sprang off. Time was in that case immediately registered and the procedure was the repeated three times every single with complete and smashed Alka-Seltzer tablets. Then comes from three many other classmates' tests would be noted and included with our own results. The speculation was that more surface area subjected and small volume would result in a quicker chemical reaction with the material. Considering that the Alka-Seltzer tablet would be fewer exposed and also have a larger quantity as a whole, the crushed tablet was considered to have a faster reaction due to its small volume and larger exposure. The hypothesis was supported. The entire Alka-Seltzer tablet had an normal of 7. 70 seconds via twelve tests, while the smashed tablet had an average of only several. 56 seconds from twelve trials. Nevertheless , errors may have occurred mainly because the tablets and film caps were not put in in synchronized occasions. The water amounts in the film containers were also not assessed accurately because they were estimated.
