A 21.5 g sample of nickel was treated with excess silver nitrate solution to produce silver metal and nickel(II) nitrate. The reaction was stopped before all the nickel reacted, and 36.5 g of solid metal (nickel and silver) is present. Calculate the mass of solid silver metal present.
If a current of 0.25 Amperes is applied to a metal object for 30 minutes in a solution of silver nitrate, it will deposit 0.503 grams of silver metal. If the same current is applied for the same amount of time in a solution of nickel sulfate, how much nickel will be deposited? Show your work
A spoon was silver-plated electrolytically in a AgNO3 solution. If 0.750 g of Ag was deposited on the spoon at a constant current of 20.0 mA, how long (in hours) did the electrolysis take? (1 mA = 1x10–3 A) 11.9 hr 9.32 hr 5.92 hr 8.76 hr 10.1 hr
Q7) A 1.23 g sample, which contains gold (Au), silver (Ag) and metal oxides, is treated with concentrated nitric acid (HNO;), which dissolves all the metals and metal oxides with the exception of the gold. The mass of yellow metal remaining is 7.4 x 10 g. The solution is then treated with aqueous sodium chloride (NaCI), which precipitates silver chloride (AgCI) and nothing else. A total of 0.196 g of AgCl is obtained. What is the percent gold and silver...
How much silver (in grams) was there in the solution if all the silver was removed as Ag metal by electrolysis for 0.55 hr with a current of 1.10 mA (1 mA = 10-3 A)?
Silver can be plated out of a solution containing Ag+ according to the half-reaction Ag+(aq)+e−→Ag(s) How much time (in minutes) does it take to plate 19 g of silver using a current of 4.8 A ? Express the time to two significant figures and include the appropriate units.
How long must a 20.0 A current flow through a solution of ZnS04 in order to produce 25.00 g of Zn? [4] 5. Time =
A solution of silver nitrate is electrolyzed and solid silver is deposited on an metal spoon. If a current of 2.0 A for 1 hour, then what mass of silver is deposited on the metal spoon? The molar mass of silver is 107.868 g/mol.
what mass of silver (Ag) metal can be produced in 1 hour in the electrolysis of Ag+ salt by a current of 12 A?
