OK solutions - but then do not write copper sulfate pentahydrate in the reactions. The temperature, mixing order, or two dropping funnels are also important. Closed or open system - it can all be important. I advise you to use deoxygenated solutions and argon as an inert gas. And watch the reaction carefully.
I don't believe in N₂O - rather  NO, or the mixture with NO₂. Higher reagent concentrations can be obtained from Cu(NO₃)₂ and KNO₂.

Jak najbardziej będę rozpuszczał w wodzie najpierw  przygotuje stężone roztwory które następnie będę wlewał do wody.

English please.

Basically OP claims he will prepare concentrated water solutions which will be then added to water.

Why adding them to water instead of just mixing?
