what ratio do I use for copper sulfate crystals and water to use as a fungicide?
Copper(I) sulfate is Cu2SO4: the ratio Cu/SO4 is 2.
The mass of water does not increase when copper sulfate is added to the water, unless the copper sulfate is hydrated. The mass of the mixture of water and copper sulfate, of course, does increase.
You could place the copper sulfate solution in an evaporation dish and let the water evaporate at room temperature over a period of days.
of couse~ can.... even 2ml of water dissolve in 4.0 grams of copper sulfate.
Copper sulfate has CuSO4 as its formula. Copper sulfate is also written copper (II) sulfate.
Copper(I) sulfate is Cu2SO4: the ratio Cu/SO4 is 2.
Copper sulfate is not black. Combined with water, as hydrated copper sulfate, it is blue. Without water, as anhydrous copper sulfate, it is white.

Why does copper sulfate change its colour when water is added
a copper sulfate solution it becomes copper (II) sulfate pentahydrate
Copper sulfate is soluble in water but doesn't react with water.
Nothing spectacular: a water solution of copper sulfate is obtained.
Not much. The Copper (II) sulfate will just dissolve in the water (at about 316g/L of water). Copper (II) sulfate is pretty friendly around water and not all that dangerous. It's used commercially.
The pH of a copper sulfate solution depends on its concentration. Typically, a 1% solution of copper sulfate has a pH of around 3-4, making it acidic.
