This is a physical change due to the fact that you are adding two substances.

Mixing salt and pepper is a physical change
Physical
It is a chemical change. CH3COOH (vinegar) + NaHCO3 (baking soda) -> CH3COONA (sodium acetate) + H2CO3 (carbonic acid)...which then immediately dissociates to... H2CO3 -> H2O + CO2
It depends on what you are mixing it with.
