AP ongeleerd AP Chem Test Unit 4 Progress Check: FRQ Name 1. For parts of the free-response question that require calculations, clearly show the method used and the steps involved in arriving at your answers. You must show your work to receive credit for your answer. Examples and equations may be included in your answers where appropriate HCl(aq) + NaOH(aq) + NaCl(aq) + H2O(1) A student was given the task of titrating a 20. m. sample of 0.10 M HCl(aq) with 0.10 M NaOH(aq). The HCl(aq) was placed in an Erlenmeyer flask. An equation for the reaction that occurs during the titration is given above. (a) According to the equation for the reaction, if the amount of the reactants is halved, how does this affect the amount of H2O(l) produced in the reaction? Please respond on separate paper, following directions from your teacher. (b) The equation above is not written in net ionic form. Write the correct net ionic equation for the reaction Please respond on separate paper, following directions from your teacher. (e) In the equation you wrote in part (b), which species is a proton acceplor? Picase respond on separate paper, following directions from your teacher. (d) How many moles of HCI are in the 20. mL sample of 0.10 M HCl(aq)? Please respond on separate paper, following directions from your teacher

On the graph, draw an X to identify the location of the equivalence point of the titration Please respond on separate paper, following directions from your teacher. The student performs a second titration using the 0.10 M NaOH(aq) solution again as the titrant, but this time with a 20. ml sample of 0.20 M HCl(aq) instead of 0.10 M HCl(aq). () The box below to the left represents sons in a certain volume of 0.10 M HCl(aq). In the box below to the right, draw a representation of ions in the same volume of 0.20 M HCl(aq).

() On the graph in part (a). carefully draw a curve that shows the results of the second titration, in which the student titrates a 20. ml sample of 0.20 M HCl(aq) with 0.10 M NaOH(aq). Picase respond on separate paper, following directions from your teacher. (h) The student made observations related to the contents of the Erlenmeyer flask during the titration. Identify an observation that could have led the student to conclude that a chemical change took place during the titration Picase respond on separate paper, following directions from your teacher
