A fictional compound AX₂ has a molar mass of 235.76 g/mol and a Ksp of 3.8742e-10. It dissociates in water based on the equation: AX2(s) ⇒ A²+, (aq) + 2X (aq) Based on this information, label the statements below as true or false. If more solid AX₂ is added to the system then [A²+] will increase. If more soluble A(NO3)2 is added to the system then [X] will increase. ✓ If the solution is heated and the solubility increases, then the heat of solution for AX₂ is endothermic. ✓ The mass solubility of AX₂ is greater than 2.17E-2 g/100mL H₂O. ✓ If soluble Nax is added to the system then [A²+] will decrease. The molar solubility of AX₂ is greater than 9.18E-4 mol/L. If more solid AX₂ is added to the system then [X] will decrease.
If 350 mL of some Pb(NO3)2 solution is mixed with 550 mL of 3.20 x 10−2 M NaCl solution, what is the maximum concentration of the Pb(NO3)2 solution added if no solid PbCl2 forms? (Assume Ksp = 2.00 x 10−5 M at this temperature.) Enter the concentration in M.
Be sure to answer all parts. Radiochemical techniques are useful in estimating the solubility product of many compounds. In one experiment, 50.0 mL of 0.080 M AgNO3 solution containing a silver isotope with a radioactivity of 74,025 counts per min per mL were mixed with 300.0 mL of a 0.040 M NaIO, solution. The mixed solution was diluted to 500.0 mL and filtered to remove all of the AgIO, precipitate. The remaining solution was found to have a radioactivity of 44.4 counts per min per mL.. What is the Ksp of AgIO,? x 10 (Enter your answer in scientific notation.)
The formula H₂SO4 + 2 KOH --> K₂SO4 + 2 H₂O describes the reaction between sulfuric acid and potassium hydroxide. In the titration done, 20 mL of KOH with an unknown concentration is put into a flask with bromthymol blue indicator. The KOH solution was titrated with a 0.25 M H₂SO4 solution. Three trials were performed and each trial yielded to an endpoint of yellow-colored solution, which is the desired endpoint. After three trials, the following readings were obtained: 15.5, 15.1, and 14.9 mL respectively. Calculate the molarity of Potassium hydroxide. (Answer must be rounded off to 2 decimal places)
An HCl solution has a concentration of 0.09714 M. Then 10.00 mL of this solution was then diluted to 250.00 mL in a volumetric flask. The diluted solution was then used to titrate 250.0 mL of a saturated AgOH solution using methyl orange indicator to reach the endpoint. 1. What is the concentration of the diluted HCl solution? 2. If 7.93 mL of the diluted HCl solution was required to reach the endpoint, what is the concentration of OH− in solution? 3. What is the concentration of Ag+ in solution?

Be sure to answer all parts. Solid NaI is slowly added to a solution that is 0.0099 M Cu+ and 0.0081 M Ag+. Which compound will begin to precipitate first? NaI CuI AgI Calculate [ Ag+ ] when CuI just begins to precipitate. × 10 M Enter your answer in scientific notation. What percent of Ag+ remains in solution at this point? %
3a) A student determines the concentration of a sodium hydroxide solution by titration with standardized KHP. S/he obtains the values: 0.190 M, 0.202 M, and 0.205 M. Should the value 0.190 M be rejected? Apply the Q Test. For three values Q must be greater than 0.94 to reject the number. Q = suspect nearest | largest - - smallest b) The student de to repeat the experiment two more The five values now include: 0.190 M, 0.202 M, 0.205 M, 0.201M and 0.203M. Use the Q Test to see if the first value may be rejected. For five values Q must be greater than 0.64 to reject the number. c) Solve for the average Molarity of the measurements from part b with and without the rejected number. Is there value in repeating an experiment several times?
