It should be noted that sodium is present as an impurity in many if not most metal salts. Because sodium imparts an especially intense color to a flame, flashes of the sodium may be observed in nearly all solutions tested. Scientific Concepts: When an element is
Science made alive: Chemistry/Elem/Elements/Sr+Ba
Barium salts give a grey/green color of the flame and strontium salts give a bright red color of the flame. When the carbonates from pottery and ceramics supplies are used, then it is wise not to store premixed powders, because of the sulfide impurity.
Flame Test Lab Instructions
In this lab we will record the flame test color of several metals by placing various metal salts on damp q-tips and placing them into a flame. We will attempt to use spectroscopes to view the separate colors of the emission spectra, but this is difficult to do under our lab conditions because the flame test is of short duration and the lab lights will be dimmed to better see the flames.
Expt 2 Calcium by visible spectroscopy
Average amount of calcium in diet: 100–250 mg/24-hour sample High amount of calcium in diet: 250–300 mg/24-hour sample Ultraviolet/visible (UV/vis) absorption spectroscopy is a technique that can be used to determine low levels of calcium. Because
