Note:- Baking soda isn't salt really.
Note- Copper has sulphur. When you mix sulphur with water, it becomes acid, non metals become acids when mixed with water.
Copper sulphate has some acids[sulphur] so, it turns blue litmus to red
Baking soda, or sodium bicarbonate, is a basic solution, so it turns red litmus blue
I hope this will help. This answer is of my understanding about acids, bases and salts, don't report this answer.
