A. 0.0750 M Na3PO4 as this solution would contain 3 Na+ and 1 PO4- ions per mole of Na3PO4 for an effective total ion concentration of 4 x .0750 or .300 M. The K2SO4 has three total ions or a concentration of .300 M as well.

A. Pb(IO3)2 + NaOH --> Pb(OH)2 + NaIO3 You balance K2SO4 + BaCl2 --> BaSO4 + KCl You balance To do this in the future: You have polyatomic ions here. You recognize polyatomic ions by: If you have MORE than 2 different elements present in the compound, then you have a polyatomic ion. If your compound does not start with NH4, then the first element is a single element and the rest is a polyatomic ion. If NH4 is the first thing in the compound, then NH4 is a polyatomic element and if the rest is a single element then it is a single element; if the rest has more than one element, then the rest is another polyatomic ion. In your equations, each compound can be represented by either an "A" or a "B" and a "C" or a "D". Where the first… [cont.]

A. Just break up all soluble compounds into ions. Leave insoluble compounds and water unbroken. so 6K+ plus 6MnO4- plus l8H+ plus 9SO-2 plus l0Na+ plus l0HSO3- yields 6 Mn+2 plus 6 SO4-2 plus 6 K+ plus 3SO4-2 plus Na+ plus SO4-2 plus l4 H20 There should be an (aq) in parenthesis behind all ions in the equation. Do the same thing in the second equation.

Asked by Jennifer T - Mon Mar 16 12:08:56 2009 - - 1 Answers - 0 Comments

A. this question is better situated at the Chemistry subsection but i'll answer anyway. Net ionic equation is one where particles that remain the same from the reactant side to the product side is omited. K2SO4+Pb(NO3)2 forms PbSO4 thus, Pb(2+) + SO4(2-) -> PbSO4 NaOH+Pb(NO3)2 forms Pb(OH)2 thus, Pb(2+) + 2OH(-) -> Pb(OH)2 Na3PO4+Pb(NO3)2 forms Pb3(PO4)2 thus, 3Pb(2+) + 2PO4(3-) -> Pb3(PO4)2

Asked by Kesha - Fri Oct 16 01:30:05 2009 - - 1 Answers - 0 Comments

A. It can be explained by solubility constants. Instead of answering the question directly, I'll direct you to the topic of solubility equilibrium which should be enough to answer your question at least in the Freshman Chem level: However, depending on your level of study, you may want to explain that using polarizability and ionic size.

A. solubility rules: 1. nitrates=always soluble 2. alkali metals and ammonium salts are always soluble 3. sulfates are soluble except in Ag, Ba, Pb, Hg, and Ca 4. halides are soluble except with Ag, Pb, and Hg 5. Hydroxides are almost insoluble except with Al, ammonium, and alkali metals. 6. phosphates, carbonates, sulfides, and chromates are all insoluble except with alkali metals and ammonium. therefore a is soluble B is soluble C is insoluble d is soluble E is soluble.
