Flame tests using metal salts | Resource | RSC Eduion

When a metal salt solution is sprayed onto the flame the electrons in the metal are excited and jump from one electron shell level to the next highest shell level. They are said to be excited . They cannot remain there so as they return to the original shell, known as the grounded state the energy gained is lost in the form of light known as emission .

Properties of Calcium Chloride – Peters Chemical Company

INCREASED DENSITY. Additions of 1 -2% calcium chlorides accelerate the set time of concrete, resulting in earlier strength development. It also increases the rate of flow of concrete (workability). Because less water can be used without loss of workability, the density of the concrete can be increased.
