The reaction equation is Cu(NO3)2 + Na2S2O4 -> CuS2O4 + 2NaNO3.

  1. Detailed information about the equation Cu(NO3)2 + Na2S2O4 -> CuS2O4 + 2NaNO3

The equation above describes the chemical reaction between copper(II) nitrate (Cu(NO3)2) and sodium thiosulfate (Na2S2O4) to produce copper(II) thiosulfate (CuS2O4) and sodium nitrate (NaNO3).

  1. Reaction conditions

The specific conditions for this reaction may vary based on factors such as temperature, pressure, and the reaction environment. However, typically, this reaction occurs under normal temperature and pressure conditions.

  1. Reaction process

During the reaction process, the copper ion Cu2+ in copper(II) nitrate interacts with the thiosulfate ion S2O42- in sodium thiosulfate to form copper(II) thiosulfate. Simultaneously, the sodium ion Na+ combines with the nitrate ion NO3- to form sodium nitrate.

  1. Occurred phenomena

The specific phenomenon in the reaction process may be quite hard to recognize because both the reactants and the products are either solid compounds or solutions that do not change color. However, if the reaction occurs in a solution, one can observe changes in color, transparency, or concentration of the solution.

Note: The provided equation may not be entirely accurate as CuS2O4 may not be the exact product of this reaction.
