(ii) the cu2+ ions are attracted to the negative electrode, where they are reduced to produce copper atoms.
write a balanced half equation for the reaction at the negative electrode.

(iii) suggest a suitable electrolyte for the electrolysis.

To save time, you can approximate the initial mass of the solid to the nearest ±1 g. for example, if you are asked to add 14.3 g of copper, add between 13 g and 15 g. which of the following sets include two samples with an equal density? which all that apply below 15.4 g gold and 18.7 g silver 15.2 g copper and 50.0 g copper 20.2 g silver and 20.2 g copper 11.2 g gold and 14.9 g gold

When a scientific theory has been tested and proved by the scientific community, it becomes a law
