Label three test tubes as either "Carbonate Ion Test", "Sulfate Ion Test", or "Phosphate Ion Test". Add two mL of the unknown solution into each test tube. Using the unknown solution, follow the procedures for the Test for Carbonate Ion, Test for Sulfate Ion, and the Test for Phosphate determination in the corresponding test tubes. The unknown solution is used as a substitute for the known samples which were used in Experiment 1. Record your results of each test in...

Q 1 & 2
1. Sodium ion (Na) and calcium ion (Ca2) produce nearly the same color in a flame test (yellow and yellow-orange, respectively). Describe a way to differentiate between the two using a solution of Na,CO and write the correct balanced equation(s). (Hint: recall the solubility rules for Na ion.) A saturated solution of an unknown solid reacted with AgNO, to give a pale yellow precipitate, and also reacted with Pb(NO), to give a white precipitate. Based on...

1. Use a molecular drawing program to construct a balanced equation for the specific reaction of 2-propanol with the Lucas reagent including structural/skeletal formulas. Do not just copy the general reaction (no R's in your answer). 2. Use a molecular drawing program to construct an equation for the reaction of each of the specific alcohols in Part A (listed in Table 1) with chromic acid including structural/skeletal formulas. Write "No Reaction" for the products if no reaction occurs. Assume the...

1. Write the balanced equation for the reaction between calcium carbonate and hydrochloric acid in water, generating aqueous calcium chloride and liberating carbon dioxide gas. (You will need this for Part 1 of the experiment!) 2. Calculate the concentration of one liter of the resulting calcium chloride solution (assuming you started with 102.7 mg of calcium carbonate) in units of molar and millimolar. Also calculate the concentration in "parts-per-million as CaCO3". (Refer to section 13.5 of your textbook, if needed.)...
