一道AP化学题
In the electroplating of nickel, 0.200 faraday of electrical charge is passed though a solution of NiSO4. What mass of nickel is deposited?
(答案 5.87g)
In the electroplating of nickel, 0.200 faraday of electrical charge is passed though a solution of NiSO4. What mass of nickel is deposited?
(答案 5.87g)
问题大体意思：电解法沉积Ni,当电量为 0.200 法拉第时,沉积镍的质量.
因为Ni2+ + 2e- = Ni,
根据 2 n(Ni) = 0.200 ,所以n(Ni) = 0.1 mol,
质量 m = 0.10 mol * 58.7 g/mol = 5.87 g
再问： 谢谢！请问法拉第是什么单位？对于2 n(Ni) = 0.200公式不太理解。
再答： 1 法拉第是1 mol 电子所带的电量。1 F = 96500 C/mol 2 n(Ni) 是Ni2+得到的电子的物质的量，右边也是。
