Solubility and common ion effect Given the following Ksp values, provide the order that Sr2+, Ca2+ and Ag+ will precipitate out of solution when IO3- is added to the solution? Ksp values Sr(IO3)2 = 3.3 * 10-7 Ca(IO3)2 = 7.1 * 10-7 AgIO3 = 3.1 * 10-8

Conceptual Questions How do you improve buffer capacity? Why is the equivalence point of a weak acid, strong base titration have a pH > 7? In comparing two weak acids, how does Ka tell us the relative strength?

Unformatted text preview: How does pKa? Solubility of salts and Common Ion What is the pH of 12.5 g of Cu(OH)2 dissolved in 1.25 L of water? (Ksp = 2.2 * 10-20) What direction would the pH change by adding Cu(NO3)2 to the solution? More Neutralization Write a neutralization reaction for HClO with NH3 Determine if products or reactants are preferred in the above reaction if Ka(HClO) = 2.9 * 108 and Kb(NH3) = 1.76 * 105....
