Vedclass · Answer

(A) The flame test is used to identify metal ions based on the characteristic color they impart to the flame. Among the alkaline earth metals,$Be^{2+}$ and $Mg^{2+}$ do not impart any characteristic color to the Bunsen flame because the energy of the flame is not sufficient to excite their electrons to higher energy levels. $BeCl_2$ is soluble in water. Therefore,the cation present is $Be^{2+}$.

$A$ chloride is significantly soluble in cold water. When placed on a $Pt$ wire and heated in a Bunsen flame,it does not impart any characteristic color to the flame. Which of the following cations is present?
