30) A 0.90M solution of a weak acid is 0.47% ionized. Determine the K of the acid. Your answer must include an ICE table... and NO rounding! 31) Determine the pH of a buffer solution made by mixing 100ml. of 0.100M acetic acid (K. = 1,8x10) with 20 ml of 0.100M NOH CHEM 104 FALL 2021 32) Determine the solubility of the sales below anmel Landing In order to earn full credit, you must complete the dissociation equations and create and ICE table PbSO4), K.-2.53x10 PbSO4(8) = 33) Determine the solubility of the salts below. In order to cam full credit, you must complete the dissociation equations and create an ICE table Cay(PO.)(s), K., -2.07x10* Ca3(PO4)2(s) = 34) Determine the solubility of Cu(10.2 in water. K-1410? 35) Determine the solubility of CaF (K. - 4.0x10 ") in 0.025M NaF solution 36) 10.0mL of 0.100M AgNO and 10.0 mL of 0.100M NaCl solutions are mixed. Compute and use that information to determine whether of Agct will precipitate (k-1.8x10 "). Don't forget to account for the dilution! 37) In the presence of NH, Cr"faq) forms the complexion CNH)"(aq) as shown in the equation below. Based on the equilibrium concentrations provided, determine the K for the reaction. You must write the equilibrium expression first Cu?" (aq) + 4NH (aq) = Ca(NH4)4(aq) 1.810- L010- 38) The graph on the right shows the titration of 25.0ml of 0.500M acetic acid (ke-18x10 ) with 0.SOOM NaOH. You should use it to determine whether your answers make sense when computing the pH (to 2 decimals) in the following three cases 50 a) At the midpoint (half-equivalence). b) At the equivalence. Don't forget to determine the total volume CE Added: in which the conyugate base is dissolved. c) After 40.0mlof Nackt were added. First, determine how much access NaOH is present and the determine the total volume of solution
