YER Background Chemistry is an experiential science and involves "doing" something. Unfortunately, online you can not actually do something BUT you can watch" a video of it. AND if you are keen, try to do the experiment at home. A structure/bonding chemist is interested in examining what is happening on the molecular level. In Experiment 1 you will investigate happens when you take Alka-Seltzer" to minimize heartburn. This is related to a reaction you may have done as a child (reacting vinegar and baking soda to watch it "foam"), Examining in complete detail how AlkItzer" reacts would require that you already understand all concepts being taught in this course. At this point in the semester, therefore, you will have to be told some information in advance, specifically what chemical reactions are taking place equations [1] and [2]). NaHCO3(p H-CO: (ap) + NaCl [1] H.CO, (a) H2O + CO. [2] + HCl(a) ? Chemical Equations What is the overall balanced equation obtained when (1) and 2) are combined Curved Arrows The sodium bicarbonate (NaHCO) in Alka-Seltzer reacts with hydrochloric acid (HCI) in the stomach to form carbonic acid (H.CO) (1), which then rapidly breaks down to form carbon dioxide gas (CO:) and water (HO) [2]. A BALANCED chemical equation demonstrates atom conservation (ic, the number and types of atoms at the start of a reaction is the same as the number and types of atoms at the end). The Stoichiometry of the BALANCED chemical reaction tells one about the ratio of reactants to each other and to the products formed. Lewis diagrams can be used to represent the bonding in a chemical species, and curved arrows can be i 0.9. w.thegistwj wing" Draw the curved arrows to show how NOOH reacts with HCI to produce NoCland H.O. chemical reactions are taking place equations Land (21) + NaCl Chemical Equations What is the overal balanced equation obtained when !!! and 2) are combined ions? (minimize NaHCO3(aq) + HCI (9) H.COM) [1] H.COM - HO + CO2 [2] The sodium bicarbonate (NaHCO) in Alka-Seltzer reacts with hydrochloric acid (HC) in the stomach to form carbon acid (H2CO3) [1], which then rapidly breaks down to form carbon dioxide gas (CO) and water (H30) [2). A LANCED chemical equation demonstrates atom conservation (ie the number and types of atoms at the start of a reaction is the same as the number and types of atoms at the end). The Stoichiometry of the BALANCED chemical reaction tells one about the ratio of reactants to each other and to the products formed. Lewis diagrams can be used to represent the bonding in a chemical species, and curved arrows can be used to show the electron movement related to the bond-breaking and bond-making that occurs when products are formed. Curved Arrows i og uthenge -- Draw the curved arrows to show how NOOH reacts with HC lo produce NaCl and HO 1 ? Limiting vs. Excess Based on the description to the left it after the NHCO, in Alko Seitzer reacts with HCl the phis 2 who was in excess HC or NaHCO, When carrying out a chemical reaction in a lab, it is virtually impossible to mix the ideal amounts of reactants as indicated by the stoichiometry of a balanced chemical Toation. One of the reactants is, therefore, measured in excess. As the reaction of Alka-Seltzer" with hydrochloric acid is an acid-base reaction, pH can be used to determine which reagent is in excess. The reagent not is excess is known as the initing reagent. Usually a chemist not only makes qualitative descriptive) observations like those above, but may also be interested making quantitative (numerical) ones. If reactions [1] and [2] are carried out as "open" systems (for example, an Erlenmyer flask), the amount of CO2(g) produced can be determined by considering how the weight of the system changes as the gas is released into the lab. Stoichiometric relationships are important to relating the amount of CO (9) produced to the amount of NaHCO, that reacts. Remember to use a claim evidence-reasoning argument whenever you are explaining" something ? How would you determine the mass of NaHCO, that would produce 0.05g of COP ? When looking quantitatively at a product produced, however, one must be careful that the reactions being studied are the only ones that are occurring. In the case of studying the reaction of Alka-Seltzer with hydrochloric acid, is this the only acid-base reaction occurring? How might the acetylsalicylic acid (ASA, or aspirin) and citric acid present in an Alko-Seltene fobiel impact this experiment
