3. Graphing is an essential skill used throughout chemistry courses and other sciences. Here is a problem dealing with the creation and use of a graph. The solubility, S, of K2SO4 is given as grams K2SO4 per 100.0 g of H20 (that is, the number of grams of K2S04 that will dissolve in 100.0 g of H20 to form a saturated solution). The experimental data are: T/°C 20 40 60 80 100 9.8 14.2 18.3 21.6 25.9 a. On graph paper, plot the solubility (ordinate, or y-axis) versus the temperature (abscissa, or x- axis). Follow the points outlined in your Lab Manual on plotting data. Your plot must include labeled axes (showing necessary units), and a title (such as "Solubility of K2SO4 in Water as a Function of Temperature"). Spread out your data (that is, "expand the axes") so that your plot covers a large portion of the page of graph paper. Use your graph to answer the questions below. b. Determine the mass of K2SO4 that will dissolve in 250.0 g of H20 to form a saturated solution at 70.0 °C. С. Determine the temperature at which 67.5 g K2SO4 will dissolve in 450.0 g H2O to form a saturated solution.

According to the Resource Conservation and Recovery Act (RCRA), waste material is classified as toxic and must be handled as hazardous if the lead concentration exceeds 5 mg/L. By adding chloride ion, the lead ion will precipitate as PbCl2, which can be separated from the liquid portion.

The following question is taken from a Chemistry Advanced Placement Examination and is used with the permission of the Educational Testing Service. Solve the following problem: MgF2(s)Mg2+(aq)+2F(aq) In a saturated solution of MgF2 at 18 C, the concentration of Mg2+ is 1.21103M . The equilibrium is represented by the preceding equation. (a) Write the expression for the solubility-product constant, Ksp, and calculate its value at 18 C.

A 0.010 M solution of the weak acid HA has an osmotic pressure (see chapter on solutions and colloids) of 0.293 atm at 25 C. A 0.010 M solution of the weak acid HB has an osmotic pressure of 0.345 atm under the same conditions. (a) Which acid has the larger equilibrium constant for ionization HA[HA(aq)A(aq)+H+(aq)] or HB[HB(aq)H+(aq)+B(aq)]? (b) What are the equilibrium constants for the ionization of these acids? (Hint: Remember that each solution contains three dissolved species: the weak acid (HA or HB). the conjugate base (A- or B- and the hydrogen ion (H+). Remember that osmotic pressure (like all colligative properties) is related to the total number of solute particles. Specifically for osmotic pressure, those concentrations are described by molarities.)
