Question

what is 2cu+, 2SO4- in science​

Answer 1

Answer:

Cu+ means it is cation it has+2 charge

SO4- means it is an anion it has -2 charge

Answer 2

Answer:

Explanation:

In equilibrium, ,,,

The equilibrium between Cu2+, copper metal and Cu+ ion has been studied, at 25°C in a series of (Na)ClO4 as well as (Na2)SO4 ionic media, by passing Cu2+ solutions through a column of finely divided copper metal. In the effluent liquid phase, which was made to percolate at a rate low enough for equilibrium to be attained. the number of equivalents of reducing agent was determined by constant-current coulometry. The measurements were performed in 0.5, 1.2 and 3 M ClO4−, and 0.1, 0.2, 0.4 and 1 M SO42− ionic media. From the experimental data the equilibrium constant at infinite dilution log K0−5.73±0.03, for Cu2++Cu(s)⇄Cu+, has been evaluated by applying the specific interaction theory [15–17]. The standard potentials of the half-reactions involving the Cu+ ion have also been recalculated.
