Question
CHEM 1405 Expe 12 Reactions in Aqncons Selutions Name: Pre Lab Questions Section: Date: 1. For cach of the salts listed below, indicate what is the cation and what is the anion in the salt by writing the correct Jormula (oot its name) for the ioas. (Note: Correct formula includes 'correct charge') Sodium Leadin Barium Irol) Aluminum Calcium Barim sulfate nitrate bromidesulfate hydroxide phosphate sulfate Salt Cation Anion 2. For each of the salts listed below, write its formula, and determine whether it is soluble or insoluble in water.(You may refer to the solubility information on page I of this handout.) Salt (Name) Sm Lead(l) Barium rol) P Potassium Cacum Barium sulfate sulfate nitrate bromide sulfate Salt (Formula) Soluble or insoluble 3. When barium ions are combined with carbonate ions, there_will bs./will not be a precipitate. Cross out the choice that is not applicable. Refer to the solubility table) Do you expect to see a precipitate when a solution of barium chloride is mixed with a solution of potassium carbonate? Give reason for your answer 4.Explanation / Answer
