When 6 xx 10^22 electrons are used in the electrolysis of a metallic salt, 1.9 gm of the metal is deposited at the cathode. The atomic weight of that metal is 57. So oxidation state of the metal in the salt is
0.635 g of a metal gives on oxidation 0.795g g of its oxide. Calculate the equivalent mass of the metal.
When 3.86 amperes current are passed through an electrolyte for 50 minutes, 2.4 gr of a divalent metal is deposited. The gram atomic weight of the metal (in grams) is
0.548 g of the metal reacts with dilute acid and liberates 0.0198 g of hydrogen at S.T.P. Calculate the equivalent mass of the metal.
On passing 3 amperes of electricity for 50 minutes, 1.8 gm metal deposits. The equivalent mass of metal is
When equal volumes of two metal are mixed together, the specific gravity of alloy is 4. When equal masses of the same two metals are mixed together the specific gravity of the alloy is 3. calculate the specific gravity of each metal.
Same quantity of electrical charge that deposited 0.583 g of silver was passed through a solution of gold salt. If 0.335 g of gold is deposited, calculate the oxidation state of gold in the given salt. At wt of Au = 197.
