Barium salt

Vedclass · Answer

(A) The flame test is used to identify metal ions based on the characteristic colour they impart to a non-luminous flame. $A$. Barium $(Ba^{2+})$ salts impart a characteristic apple-green colour to the flame. $B$. Calcium $(Ca^{2+})$ salts impart a brick-red colour. $C$. Borates (like borax) can produce a green flame,but the question specifically asks for a salt tested by $Pt$ wire in the context of metal cation identification,where Barium is the standard answer. $D$. Lead $(Pb^{2+})$ salts typically do not give a characteristic flame colour. Therefore,the correct option is $A$.

Which one of the following salts gives a green-coloured flame when the salt is tested by a $Pt$ wire?
