List the eight known salts shown in Part A, the ions into which they disassociate (balanced!), and the correct name for each salt. For example:
Calcium chloride: CaCl2 (s) —> Ca2+(aq) + 2Cl- (aq)
Part A:
Ionic compounds:
Pb(NO3)2
Na3PO4
KOH
Na2S
KI
CaCl2
AgNO3
ZnSO4
Pb(NO3)2 is lead nitrate
Pb(NO3)2 (s) -------> Pb2+ (aq) + 2NO3- (aq)
Na3(PO4) is sodium phosphate
Na3(PO4) (s) -------> 3Na+ (aq) + PO43- (aq)
KOH is potassium hydroxide
KOH (s) -------> K+ (aq) + OH- (aq)
Na2S is sodium sulfide
Na2S (s) -------> 2Na+ (aq) + S2- (aq)
KI is potassium iodide
KI (s) -------> K+ (aq) + I- (aq)
AgNO3 is silver nitrate
AgNO3 (s) -------> Ag+ (aq) + NO3- (aq)
ZnSO4 is zinc sulfate
ZnSO4 (s) -------> Zn2+ (aq) + SO4 2- (aq)
CaCl2 is already given as example

Completing and Balancing Neutralization Reactions 10 of 18 For example, if you have a cation with a 1+ charge and an anion with a 2-charge, you will need two cations to balance the charge: I(1+ charge on cation)(2)]+[(2-charge on anion)(1)) = (+2) + (-2) = 0 Complete the following statements regarding the number of cations and anions present in the various ionic compounds. Match the numbers to the appropriate blanks in the sentences below. Make certain each sentence is complete...
Experiment 8 Solubility of lonic Precipitates Lead chloride is a slightly soluble salt. When lead chloride dissolves in pure water or an aqueous solution, the small quantity that dissolves completely ionizes and reaches equilibrium in a saturated solution, PbCl(s) ® Pb (aq) + 2Cl(aq) Kp = [Pb (C) (1) Lets be the molar solubility of lead chloride. In pure water, s = [Pb ) = (CH) / 2. In a solution containing Cl, a common ion to lead chloride, s...
Conductivity of Solutions For Che 2A at RCC Introduction Electrolytes are compounds which conduct electricity when dissolved in water. Strong electrolytes consist of ionic compounds which dissociate completely when dissolved in water, AND molecular compounds which completely ionize when dissolved in water. The reactions below illustrate the dissociation reaction of strong electrolytes: Na (aq) + Cl(aq) но NaCl(s) H30 CaBra(s) HO HCl(e) Ca(aq) + 2Br (aa) H*(aq) + C'(aq) Conductivity is a measure of the ability of water to pass...

Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...
