When copper metal is added to nitric acid, the following reaction takes place Cu (s) + 4 HNO₃ (aq) → Cu(NO₃)₂ (aq) + 2 H₂O (l) + 2 NO₂ (g) Calculate the volume of NO₂ gas collected over water at 25.0 °C when 8.13 g of copper is added to excess nitric acid if the total pressure is 726 mm Hg. The vapor pressure of water at 25.0 °C is 23.8 mm Hg.

Calculate the solubility of barium sulfate. BaSO4 in units of grams per liter. Ksp (BaSO4) = 1.1x10-10 solubility = AL The equilibrium concentration of chloride ion in a saturated lead chloride solution is M. In the presence of excess OH, the Ar+ (aq) ion forms a hydroxide complex ion. Al(OH)4 Calculate the concentration of free Ap+ ion when 1.56x10-mol Al(CH2C00)3(s) is added to 1.00 L of solution in which [OH-] is held constant (buffered at pH 12.10). For Al(OH)4, Ke=...

A) 10x10 mol/L of BaCl2 are added to a saturated BaSO4 solution. Given that the solubility product constant of barium sulfate is 1.2x10-10 find the equilibrium concentrations of Ba2+ and SO42- ions after the addition of BaCl2. B) The pH of an originally acidic solution containing 10-3 CaCl2 and 10-1 M oxalic acid (H2C204) is raised slowly. At what pH value will calcium oxalate (CaC204) first precipitate? ( Assume that CaCl2 completely dissociates into its constituent ions) Ksp (Ca C204)...

After the dissolution of the copper in nitric acid, sodium hydroxide is added to the solution. Some of the sodium hydroxide neutralizes the excess nitric acid added to promote the reaction with copper. Write the chemical equation for the reaction between sodium hydroxide and nitric acid.
Why does PbF2 increase in solubility when acid is added to a saturated solution?
Why does PbF2 increase in solubility when acid is added to a saturated solution?

Explain the relationship between the average moles of strong acid that must be added to change the pH of 25 mL of each buffer by one pH unit and the [Conj. base]/[Weak acid] ratio for the buffer. (What happens to the average number of moles of strong acid that must be added when the [Conj. base]/[Weak acid] ratio decreases? Why does the average number of moles of strong acid change as it does?)
What reaction occurs when sodium hydroxide is added to the stearic acid in cyclohexane and water?...
What reaction occurs when sodium hydroxide is added to the stearic acid in cyclohexane and water? How does this change the solubility of cyclohexane in water? Does HCl reverse this reaction when it is added? If so why? Does sodium chloride have the same type of behavior as stearic acid or is it different? Explain why these two solutes are the same or different. (Please answer in your own words.)
