Atomic Theory Lab Report

Atomic theory is the underlying model of this lab investigation. There are five important principles of this model; one all matter is composed of submicroscopic particles called atoms. Two all atoms of given element are identical. Three all atoms of one element have the same mass, and atoms from different elements have different masses. Four atoms can be combined with other atoms to form molecules, and molecules can be split apart into individual atoms. Five atoms are not created or destroyed during a chemical reaction that results in production of a new substance. According to the atomic theory, a chemical reaction is the rearrangement of atoms. This rearrangement is set up like an equation and with this equation both side must have the same

When we reacted acetate acid and sodium bicarbonate in a ratio of 1:4, 97 ml of CO2 was produced and the product was neutral(7) as seen on graph. When we repeated this with 2:1 ratio, 47 ml of CO2 was produced and the product was more acidity(6) as seen on graph. In a perfect ratio( the ratio where the reactants are all use to make the product) of acetate acid and sodium bicarbonate, both reactants will be perfectly used up and the PH would be neutral. This what happened with the frist ratio, which is why the PH was neutral. In the second ratio of acetate acid and sodium bicarbonate, the PH was more acidic, so there was acetate acid leftover. The data had errors because ratios 1:4, 1:2, and 2:3 all had a neutral PH(7) as seen on graph. This evidence shows that we never had the prefect mole ratio of acetate acid and sodium bicarbonate because we always had left over reactants when tested our ratios. Because our ratios were not perfectly balanced as atomic theory states atoms are not destroyed when when it made the new product and the ratio was not perfectly balanced the was left over
