Vedclass · Answer

(A) The flame test is used to identify metal cations based on the characteristic color they impart to a Bunsen flame. $Ba^{2+}$ gives an apple-green color,$Ca^{2+}$ gives a brick-red color,and $Pb^{2+}$ gives a pale bluish-white color. $Mg^{2+}$ does not impart any characteristic color to the Bunsen flame because the energy required to excite its electrons is too high to be provided by the flame. Therefore,$Mg^{2+}$ is the correct cation.

$A$ chloride salt dissolves appreciably in cold water. When placed on a platinum wire in a Bunsen flame,no distinctive color is noted. Which cation could be present?
