Question:

Imagine that saturated solutions of barium chloride (BaCl) and potassium sulfate (K,SO.) e mixed. A white precipitate forms,

Imagine that saturated solutions of barium chloride (BaCl) and potassium sulfate (K,SO.) e mixed. A white precipitate forms, and the solution is found to contain potassium chloride. (a) What is the name of the precipitate? (b) Write an equation for the reaction that occurred. (c) Which are the spectator ions in this reaction? 2. Consider the compound naphthalene. Based in the rule "Like Dissolves Like", which should be a good solvent for naphthalene and why: benzene, water, acetone? (Hint: Use your textbook and/or other resources to help you identify the structure of the named compounds) 2. When mixing the ionic solution pairs, is the quantity of each solution added to the test tube important? Why or not? let the water solubility of following compounds: RBCI, NHLNO, Pbs, BaSO4. AgBr 3. Define a homogenous solution

Answers

1. a) BaSO4 - Barium Sulfate is the name of the precipitate

b) Reaction equation : BaCl2(aq) + K2SO4(aq)\rightarrow BaSO4(s) + 2 KCl(aq)

c) Spectator ions : Cl- and K+
