Exploring Atomic Structure & Electromagnetic Radiation
The question we were trying to answer was what are the identities of the unknown solutions. We were supposed to do this by figuring 7 known solutions with the flame test and then decide what solution was the unknown. During our investigation, we turned a bunser burner to an inner blue flame and we had toothpicks with solutions in the seven known solutions were calcium chloride, barium chloride, copper chloride, lithium chloride, potassium chloride, strontium chloride. The other four unknown solutions were one of those. We conducted a flame test in this stuff because each element has the different amount of electrons an when the electrons get excited they absorb the energy and when they go back to ground state the electrons release energy in the form of light. So every element has its own different shades of color when exposed to a flame test. Data elements flame color Calcium Cholride Dark Orange Barium Chloride Yellow & Green Copper Chloride Gr...
