Question

you are conducting a flame test with three unknown substances. the flames turn red, blue, and yellow. based on the flame test, which metals are likely present in each substance?

Explanation:

Flame tests are used in chemistry to identify metal ions. Different metal ions produce different colored flames when heated. Calcium typically gives a red flame, copper (II) gives a blue - green to blue flame, and sodium gives a bright yellow flame.

Answer:

Red flame - likely calcium (\(Ca^{2 + }\)), blue flame - likely copper (\(Cu^{2+}\)), yellow flame - likely sodium (\(Na^{+}\))
