68. Aluminum ion may be precipitated from aqueous solution by addition of hydroxide ion, forming Al(OH)3. A large excess of hydroxide ion must not be added, however, because the precipitate of Al(OH)3 will redissolve as a soluble compound containing aluminum ions and hydroxide ions begins to form. How many grains of solid NaOH should be added to 10.0 mL of 0.250 M A1Cl3 to just precipitate all the aluminum?
Solutions of hydrogen in palladium may be formed by exposing Pd metal to H2 gas. The concentration of hydrogen in the palladium depends on the pressure of H2 gas applied, but in a more complex fashion than can be described by Henry's law. Under certain conditions, 0.94 g of hydrogen gas is dissolved in 215 g of palladium metal (solution density = 10.8 g cm3). (a) Determine the molarity of this solution. (b) Determine the molality of this solution. (c) Determine the percent by mass of hydrogen atoms in this solution.
Fluoridation of city water supplies has been practiced in the United States for several decades. It is done by continuously adding sodium fluoride to water as it comes from a reservoir. Assume you live in a medium-sized city of 150,000 people and that 660 L (170 gal) of water is used per person per day. What mass of sodium fluoride (in kilograms) must be added to the water supply each year (365 days) to have the required fluoride concentration of 1 ppm (part per million)that is, 1 kilogram of fluoride per 1 million kilograms of water? (Sodium fluoride is 45.0% fluoride, and water has a density of 1.00 g/cm3.)
Gold metal will not dissolve in either concentrated nitric acid or concentrated hydrochloric acid It will dissolve, however, in aqua regia, a mixture of the two concentrated acids. The products of the reaction are the AuCl4 ion and gaseous NO. Write a balanced equation for the dissolution of gold in aqua regia.
How many mL of HCI, 0.1 M, will you need to prepare 0.700 L of HCL, 0.025 M? Student A and Student were analyzing the initial set up of the first problem. Step 1: Identify and label knowns and unknown •Known Unknown M (initial) = 0.1 M V(initial) = ? mL M (final ) = 0.025 M V (final) = 0.700 L Step 2: Write the base equation for dilution M(1) x V(i) = M (f) x V (f) Step 3: Solve for the unknown and substitute the values. V(i) = (0.025 M)(0.700 L) = 0.175 L 0.1 M Student B said, "The dilution equation works, because the number of particles of solute that is transferred does not change during the dilution." Student A replied, "That is correct. You only add water to dilute the solution, so the number of solute particles does not change." You consider Student A and Student B to be correct.
