Would the following procedural errors result in an incorrectly high or low calculated percent NaOCl in the commercial bleaching solution? Briefly explain. a) A student failed to allow the volumetric pipet to drain completely when transferring commercial bleaching solution to the volumetric flask. b) A student blew the last drops of bleaching solution from the pipet into the Erlenmeyer flask when transferring diluted bleaching solution to the flask. c) A student began a titration with an air bubble in the buret tip. The bubble remained in the buret tip during the first titration, but it came out of the tip with the titrant released during the second titration. d) A student added diluted bleaching solution and HCI solution to aqueous KI solution in Erlenmeyer flasks 1 and 2 before beginning the titration in Erlenmeyer flask 1.

Read the experiment and answer the following questions as directed by your instructor. 1. In this experiment, you will use potassium hydrogen phthalate (abbreviation KHP, formula HKC8H4O4) to standardize (to determine the concentration precisely of) the NAOH solution. What is the molar mass of KHP?
2. The police found a small zip-lock bag containing 15.36 gram of a powder on the victim's nightstand. To find out what the substance was, the forensic scientist added it to 80-ml solution of 1.0 mol/L NaCl and analyzed the products. One product was a precipitate with the mass of 10.46g . The other product was sodium nitrate. The lab technician quickly ran the analysis on the precipitate and found the molar mass of this precipitate is 278.10 g/mol. What could be the name and formula of the precipitate? Write the balanced chemical equation and net ionic equation for the reaction, including the states. Determine the limiting and excess reactant in b). What is the percentage yield of the precipitate? . If the value is less than 80%, eliminate the study. .

What happens if a solute is added to a saturated solution? A) Nothing will happen, solute will not mix with a saturated solution. B) The added solute provides a template for the solid to begin to crystallize from solution, and a precipitate will form. C) The added solute makes the solution less saturated. D) The added solute provides a template for the gas to begin to boil from solution, and a gas will form. Why is A false?

A student carried out an experiment trying to prepare tetra-methyl-ammonium tri-iodide.The student weighed 1.13 g tetra-methyl-ammonium iodide into a beaker containing 25 mL ethanol, and then added 1.57 g of iodine. The mixture was heated gently, whilst stirring, on a hotplate until tetra-methyl-ammonium iodide, a white powder, was completely dissolved. After the mixture was allowed to cool down to room temperature, the mixture was further cooled on ice. After filtration on a Buechner funnel, washing with diethyl ether and leaving it under vacuum suction for a couple of minutes, the student recovered the product and weighed it. The mass of the obtained tetra-methyl-ammonium triiodide was 1.62 g.What is the yield of the reaction in percent [%]? For the calculation, assume that the product is completely dry and pure, so there are no impurities like side-products, unreacted educts, or solvent residues.
