Colorless.
Hydrogenic ion
Since copper (I) chloride has only limited solubility in water I will assume you mean copper (II) chloride, CuCl2. Then the ions will be Cu2+ and Cl-.
The SO42- ion is named sulfate.

The negative ion for barium sulfate is sulfate (SO4) with a charge of 2-.
The sulfate ion itself does not contribute color to a solution, but the accompanying cation may contribute color.
Sulfate/Sulphate dissolved in water is blue in color. That's COPPER sulphate; there are many other sulphates which have many different colours, or are colourless.
You have to specify the sulphate of which element.
Sodium sulfate in water typically appears colorless. When dissolved in water, sodium sulfate molecules dissociate into sodium ions (Na+) and sulfate ions (SO4^2-), which do not impart any color to the solution.
The potassium ion is K+ and the sulfate ion is SO42-
Hydrogenic ion
Blue is the solution's color When blue CuSO4.5H2O (copper(II) sulfate pentahydrate) is dissolved, the solution turns blue. When white CuSO4 (anhydrous copper(II) sulfate) is dissolved, the solution turns also blue.
Since copper (I) chloride has only limited solubility in water I will assume you mean copper (II) chloride, CuCl2. Then the ions will be Cu2+ and Cl-.
The SO42- ion is named sulfate.
NH4HSO4 is acidic. When dissolved in water, it forms ammonium ion (NH4+) and hydrogen sulfate ion (HSO4-), which can donate a hydrogen ion (H+) to the solution, making it acidic.
