51 Report Sheet Name Rear Chem 121 Lab Partners Procedure A (lonic Solutions) Conductivity results: Strong. Weak, or Non- Many, few or no ions electrolyte? produced in water? H2O weak we few Glycerol Ascorbic acid NaCI HCI St on g For the strong electrolytes, write chemical reactions that communicate what the compounds form when they dissolve in water Procedure B (lonic Reactions) Observations before adding Na:CO Compound in test tube Solubility before adding Na CO, Solubility after adding NasCO, (SOL = soluble, IN-insoluble) ISOL-soluble.PPT-precipitat H20 SOL NaCI CaCl2 NaNOs KBr Solubility hypotheses: Make hypotheses about the solubility properties (SOL or IN) of the following: Group 1A ions in the presence of group 7A ions? Group 1A ions in the presence of carbonate? Group 2A ions in the presence of group 7A ions? Group 2A ions in the presence of carbonate? Group 1A ions in the presence of nitrate? Group 2A ions in the presence of nitrate?

Answer 1

1) Soluble (Group 1A ions in presence of group 7A)

2)Soluble (Group 1A ions in the presence of carbonates)

3)Soluble (Group 2A ions in the presence of group 7A)

4)Insoluble (Group 2A ions in the presence of Carbonates)

5) Soluble ( Group 1A ions in the presence of Nitrate)

6) Soluble (Group 2A ions in the presence of Nitrate)
