21. during the flame test lab, all of the substances tested were compounds of a metal and chlorine. these are called chloride compounds. each gave a different color flame. which conclusion below can be made from this information. (1 point) the chloride ion determines the color of the flame. only chloride compounds can give off flames. the metal ion determines the color of the flame. the color of the flame is determined by the color of the compound.
Answer
Brief Explanations:
In flame - tests of metal - chloride compounds, the chloride ion is common among all tested substances while the metal ions vary. Since each gives a different color flame, it is the metal ion that determines the flame color. Chloride ions are not responsible as they are the same across all samples. Many non - chloride compounds can also give off flames, and the flame color is not determined by the compound's color but by the metal ion's electronic transitions.
Answer:
The metal ion determines the color of the flame.
