What is the effect of substituting soluble metal salts such as NaCl and K₂CO₃ for HCl or (NH₄)₂CO₃ in the qualitative analysis scheme for separating the five Analytical Groups? A)You can no longer tell if your original sample contained Na⁺ or K⁺. B)There is no effect on the analysis since Na⁺ and K⁺ do not form a precipitate. C)The NaCl and K₂CO₃ are not pure,analytical grade materials. D)Potassium ion forms a precipitate with sulfide ion. E)Na⁺ and K⁺ react violently with acids such as H₂S,producing highly flammable and potentially explosive hydrogen gas.

Substituting NaCl and K₂CO₃ for HCl or (NH₄)₂CO₃ can interfere with the detection of Na⁺ or K⁺ in the original sample, as these ions are already present in the substituted reagents.
