Consider the half reaction below.

Upper C u superscript 2 plus (a q) plus 2 e superscript minus right arrow upper C u (s).

Which statement best describes what is taking place?
Copper is being oxidized.
Copper is being reduced.
Copper is losing electrons.
Copper is a reducing agent.

so what is the problem with your lab report and whats the subject of the lab report? i will you

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

the answer is 0.42 is that is an option. this question provides no info
