- Calculate the solubility in grams per 100 mL of BaF2 in a 0.10 M BaCl2 solution.arrow_forwardThe Handbook of Chemistry and Physics (http://openstaxcollege.org/l/16Handbook) gives solubilities of the following compounds in grams per 100 mL of water. Because these compounds are only slightly soluble, assume that the volume does not change on dissolution and calculate the solubility product for each. (a) BaSiF6, 0.026 g/100 mL (contains SiF62- ions) (b) Ce(IO3)4, 1.5102 g/100 mL (c) Gd2(SO4)3, 3.98 g/100 mL (d) (NH4)2PtBr6, 0.59 g/100 mL (contains PtBr62- ions)arrow_forwardWrite net ionic equations for the reaction of H+ with (a) Fe2S3 (b) Mg(OH)2 (c) MgCO3 (d) Pt(NH3)42+ (e) Hg2I2arrow_forward
- Each pair of ions below is found together in aqueous solution. Using the table of solubility product constants in Appendix J, devise a way to separate these ions by adding a reagent to precipitate one of the ions as an insoluble salt and leave the other in solution. (a) Cu2+ and Ag+ (b) A13+ and Fe3+arrow_forwardCalculate the equilibrium constant at 25 C for the reaction 2 Ag+(aq) + Hg() 2 Ag(s) + Hg2+(aq)arrow_forwardCalculate the mass of manganese hydroxide present in 1300 mL of a saturated manganese hydroxide solution. For Mn(OH)2, Ksp = 2.0 1013.arrow_forward
- The photographs below (a) show what occurs when a solution of iron(III) nitrate is treated with a few drops of aqueous potassium thiocyanate. The nearly colorless iron(III) ion is converted to a red [Fe(H2O)5SCN)2+ ion. (This is a classic test for the presence of iron(III) ions in solution.) [Fe(H2O)6]3+(aq) + SCN(aq) [Fe(H2O)5SCN]2+(aq) + H2O() (a) As more KSCN is added to the solution, the color becomes even more red. Explain this observation. (b) Silver ions form a white precipitate with SCN ions. What would you observe on adding a few drops of aqueous silver nitrate to a red solution of [Fe(H2O)5 SCN]+ ions? Explain your observation.arrow_forwardsolve the following parts a. Would the addition of K2SO4 to a saturated solution of CaSO4 cause the solubility to increase or decrease? Explain your answer in words not with a calculation. b. Balance the following redox reaction under basic conditions. Cr(OH)3(s) + TiO2(s)→Ti2+(aq) + CrO42-(aq)arrow_forward4 A sample of solid Ca(OH)2 was stirred in water at a certain temperature until the solution contained as much dissolved Ca(OH)2 as it could hold. A 84.3-mL sample of this solution was withdrawn and titrated with 0.0771 M HBr. It required 86.7 mL of the acid solution for neutralization. (a) What was the molarity of the Ca(OH)2 solution? M (b) What is the solubility of Ca(OH)2 in water, at the experimental temperature, in grams of Ca(OH)2 per 100 mL of solution? g/100mLarrow_forward
- Write the balanced NET ionic equation for the reaction when aqueous KBr and aqueous AgC₂H₃O₂ are mixed in solution to form aqueous KC₂H₃O₂ and solid AgBrarrow_forwarda three step process is required in order to determine the concentration of NO3- in a basic solution: 1) Zinc metal reduces Nitrate ions into ammonia in basic environments2) the ammonia is transferred to a solution with a known excess of HCl3) the unreacted HCL is titrated with NaOH A) write a balanced equation for each process B) a 25.00ml basic Solution containing an unknown concentration of NO3- was treated with zinc metal, the ammonia gas from the reaction was reacted with a 50ml solution of 2.5*10^-3M of HCl, the remaining unreacted HCL was then titrated to the stochiometric point with 28.22ml of 1.5*10^-3 NaOHWhat is the molar concentration of NO3- in the original solution?arrow_forwardThe hardness of water (hardness count) is usually expressed in parts per million (by mass) of CaCO3. What is the molar concentration of Ca2+ ions in a water sample with a hardness count of 175mg CaCO3il? How many milliliters of concentrated sulfuric acid, 94.0% (w/w), specific gravity of 1.831 are required to prepare 1 liter of a 0.100 M solution? The solubility-product constant for Ce(IO3)3 is 3.2x1010. What is the Ce3+ concentration in a solution prepared by mixing 50.0 ml of 0.0250 M Ce3.. with 50.00 ml of water?arrow_forward
