Procedure: Place a pea-size sample of aluminum potassium sulfate dodecahydrate (a stable compound of the aluminum ion) in 2 mL of water. With tweezers, add one pellet of sodium hydroxide and stir slowly. If a precipitate remains when the entire pellet has dissolved, add a second pellet and dissolve. Then add 6 mol·L-' hydrochloric acid dropwise, stirring between the addition of each drop. Continue until you have added 20 drops. Report: (a) Write balanced net ionic equations for the two reaction steps involved in the addition of hydroxide ion. Write your initial aluminum species as the hexaaquaaluminum ion [Al(OH2)s]³*(ag). (b) Write balanced net ionic equations for the two reaction steps involved in the addition of hydrogen ion. (c) What is the common name of aluminum potassium sulfate?

Question 4 Three students studied the following solubility curve. They were asked to determine the 160 KNO, amount of NH,CI that needs to be added to 58 g NH CI to create a saturated solution at 140 NaNO 80°C. 120 100 KBr Student 1 said 25 g more would need to be added, student 2 said 22 g and student 3 said 17g NH CI needs to be added.

Choi is fond of carbonated beverages so he crafted his own soda formulation called “Sodalicious.” Ulan, who is a fellow enthusiast, also made her own formulation which she called “Soda Pop!” to challenge his friend Choi. To know which formulation is better, they sought to determine the carbonic acid content of their soda formulations using titration. In the first part of their experiment, a 0.5 Mlabeled NaOH solution was standardized against 0.350 grams of KHP (MW = 204.22 g/mol) primary standard that is 99.6% pure. The titration required 3.16 mL of the NaOH solution to reach the phenolphthalein endpoint. In the second part of their experiment, Choi and Ulan independently prepared their samples by taking 25.0-mL of their soda sample and diluting it to 30.0 mL. Using the same titrant and indicator, Choi’s “Sodalicious” required 1.39 mL of the standardized titrant to reach the endpoint, while Ulan’s “Soda Pop!” required 0.926 mL of the same titrant to reach the endpoint. D. Calculate…

Suppose you are given three bottles, labeled A, B, & C; each contains an aqueous solution. You are told that the possible solutions are: sodium hydroxide, nickel(II) chloride, potassium thiocyanate, sodium acetate, and pure water. Only one type of solution is present in each bottle and the con 0.5 M unless otherwise noted. Several tests are performed, and the results are summarized in the flow chart displayed on the right. Based on these results, assign the contents of the bottles and write a brief justification for each assignment. (The type of pH paper you will use is the same as the one described in the chemical foundations section).

You place 0.03531g of CaCl₂ into a 500.0 mL volumetric flask and dissolve the solid with water to the mark on the flask. You then dilute 2.75 mL of this solution to 50.0 mL in a volumetric flask. What is the concentration of Ca in ppm in the resulting solution? [You can assume a density of 1.000 g/mL for the solution]
