Explanation:
This question is incomplete however, the answer is straight forward.
A salt is a compound formed as a result of the neutralization reaction between an acid and a base. The salt formed comprises of the metal from the base and the non-metal from the acid, as shown below
HCl + NaOH ⇒ NaCl + H₂O
Hence, we can say a salt has a metallic and non-metallic component.
Flame test experiment is generally used to detect the presence of metal ions by "releasing" several metallic colour change. Thus, the part of the salt that must have visually responded to the flame test is the metallic component.
