Tutor description

Unit 3 Design Your own Experiment: Factors that Affect the Rate of a Reaction Portfolio Introduction: An antacid tablet contains citric acid and sodium bicarbonate (baking soda). When you drop the tablet in liquid, the acid and the baking soda react – this produces the fizz. 3 HCO3-1(aq) + H3C6H5O7 (aq)  3 CO2 (g) + 3 H2O + C6H5O7-3(aq) bicarbonate ion citric acid citrate ion Several factors affect the rate of a reaction. In this investigation, you will design experiments to test three factors that may affect the rate of the reaction that takes place when an antacid tablet dissolves in a liquid................................ .....................

In this investigation, you will design experiments to test three factors that may affect the rate of the reaction that takes place when an antacid tablet dissolves in a liquid.Factors that affect the rate of reaction: List the 4 factors that affect the rate of reaction and why with altering each factor, the factor affects the rate of the reaction. (Minimum 3 sentences for each explanation)Possible Materials: jars, antacid tablets (i.e. generic antacid tabletsWalgreens, CVS, RiteAid, Target, etc.), Tums, Prilosec, Alka-Seltzer, etc.), water, ice, timing device, thermometer, measuring spoons, measuring cupsProcedure:1. Choose three factors to investigate (i.e. temperature, concentration, particle size and catalyst).**Avoid using catalyst due to: hard to come by and it might not be a pure catalyst, therefore, could cause a different reaction**2. Form 1 hypothesis for each factor about how
