Question

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

• A. $B{e}^{2+}$
• B. $B{a}^{2+}$
• C. $P{b}^{2+}$
• D. $C{a}^{2+}$

Answer 1

Answer: (A)

$B{e}^{2+}$

Beryllium chloride dissolves appreciably in cold water.When placed on a Pt wire in a Bunsen flame,no distinctive colour is noted. Hence, $B{e}^{2+}$ cation could be present. The chlorides of alkaline earth metals except Be and Mg produce color to flame.
