A metal chloride dissolves appreciably in cold water. When placed on a platinum wire in Bunsen flame no distinctive colour is noticed, the cation would be
$\mathrm{Mg}^{2+}$
$\mathrm{Ba}^{2+}$
$\mathrm{Pb}^{2+}$
$\mathrm{Ca}^{2+}$
Solution
$\mathrm{MgCl}_{2}$ is soluble in water and does not give flame test. Other give flame test.
