Not necessarily. They might be blue, green, or essentially white depending on how many waters of hydration are associated with the copper (II) ion. It's very easy to see this if you just take some copper (II) sulfate pentahydrate (blue vitriol) in a test tube and heat it; as the waters of hydration are driven off, the crystals turn white (some people call it a very light green; it looks white to me). When the crystals are allowed to cool they will absorb water from the air and eventually turn blue again. Aqueous solutions of copper (II) compounds are blue, as far as I know; at least I can't think of any counterexamples.
Compounds of zinc appear white because they absorb light across the visible spectrum, reflecting all colors equally. Compounds of copper have color because they absorb certain wavelengths of light and reflect others, resulting in the perception of color. Copper compounds can exhibit various colors like blue (copper(II) sulfate) or green (copper(II) chloride) based on the electronic structure of the copper ion.
Sorry, but most copper compounds are some shade of blueor green, not colorless at all!
The colour of Copper sulphate is blue because Copper ions absorb light in all frequencies except blue which is reflected instead.
Copper sulfate itself is white/colorless when anhydrous. However, it's hygroscopic and the pentahydrate (the usual form) is blue... in fact, it's just about the same color as the sidebar over to the left there.
There is no charge. All compounds are electrically neutral. If you mean the charges of the component ions, copper carries a 2+ charge and the hydroxide ions carry a 1- charge.
Copper compounds are used in fireworks to produce blue and green colors in the flame. When heated, copper ions emit these vibrant colors, adding variety to the visual display of the fireworks. Copper compounds like cupric chloride and copper oxide are commonly used in pyrotechnics for this purpose.

Crystallized copper sulfate appears as bright blue, transparent crystals. It often forms in a pentahydrate form, meaning it contains five water molecules within its crystal structure, giving it a distinctive blue color.

Flame colours depend on just the metal ion. All copper compounds give the same colour, green.

No. Like virtually all ionic compounds copper II sulfate is a solid at room temperature. It is, however, soluble in water so you would be able to find an aqueous solution of t.
No, copper does not eventually lose all of its electrons. Copper typically forms stable compounds by either losing or gaining electrons to achieve a full outer electron shell.

Copper can bond with elements such as oxygen, sulfur, and chlorine to form various compounds. Some common examples include copper oxide, copper sulfide, and copper chloride. These compounds have different properties and uses in various industries.
