Q: What is the identification of anion and cation? how did you find it

Answer 1

Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as Sodium Chloride .

Calcium chloride imparts a yellowish-red color to a flame. A yellowish-red color is imparted to the flame by calcium chloride. The color is not as bright yellow as the sodium flame color. ... Aluminum chloride or magnesium chloride can be used to demonstrate that chlorine imparts no color to the flame.
