My work requires dissolving these oxides. I tried with some solvents, but it did not work. I only want the names of the solvents
Hello Mrs. Nina Bou
My suggestion to you is to complete your information on the required materials first. Also, you can read articles and research studies related to the topic of your work.
https://en.wikipedia.org/wiki/Copper(II)_oxide#:~:text=Copper(II)%20oxide%20or%20cupric,it%20is%20known%20as%20tenorite.
Copper(II) oxide dissolves in mineral acids such as hydrochloric acid, sulfuric acid or nitric acid to give the corresponding copper(II) salts:[4]
CuO + 2 HNO3 → Cu(NO3)2 + H2O
CuO + 2 HCl → CuCl2 + H2O
CuO + H2SO4 → CuSO4 + H2O
https://en.wikipedia.org/wiki/Tin(IV)_oxide
Although SnO2 is insoluble in water, it is amphoteric, dissolving in base and acid.[13] "Stannic acid" refers to hydrated tin (IV) oxide, SnO2, which is also called "stannic oxide."
Tin oxides dissolve in acids. Halogen acids attack SnO2 to give hexahalostannates,[14] such as [SnI6]2−. One report describes reacting a sample in refluxing HI for many hours.[15]
SnO2 + 6 HI → H2SnI6 + 2 H2O
Similarly, SnO2 dissolves in sulfuric acid to give the sulfate:[11]
SnO2 + 2 H2SO4 → Sn(SO4)2 + 2 H2O
SnO2 dissolves in strong bases to give "stannates," with the nominal formula Na2SnO3.[11] Dissolving the solidified SnO2/NaOH melt in water gives Na2[Sn(OH)6], "preparing salt," which is used in the dye industry.[11]

Dr. Joy Chakraborty added an answer
TiO2 is not usually soluble in common polar or non-polar solvents. The solubility of titanium dioxide is related to solutes. It is insoluble in dilute alkali, dilute acid, but soluble in hot concentrated sulfuric acid, hydrochloric acid, hydrofluoric acid and nitric acid but not in the form of TiO2 but as a salt like sulfate, chloride, nitrate etc. Titanium dioxide can melt in the alkali (sodium hydroxide, potassium hydroxide) or alkali metal carbonate (sodium carbonate, potassium carbonate). Any one of which i have mentioned with Titanium dioxide can be transformed into soluble acid titanate.

Zinc oxide is an amphoteric oxide. It is nearly insoluble in water, but it will dissolve in most acids, such as hydrochloric acid:[27]
ZnO + 2 HCl → ZnCl2 + H2O
Solid zinc oxide will also dissolve in alkalis to give soluble zincates:
ZnO + 2 NaOH + H2O → Na2[Zn(OH)4]
