Name : two colourless metal ions

Open in App

Solution

Salts of representative elements are generally colourless so salts of elements of groups $1, 2$ and $13$ to $17$ are colourless.

Hence, $N a^{+}, C a^{2 +}$ are colourless metal ions as they belong to groups $1$ and $2$ respectively.

Name : two colourless metal ions

Salts of representative elements are generally colourless so salts of elements of groups 1,2 and 13 to 17 are colourless. Hence, Na+,Ca2+ are colourless metal ions as they belong to groups 1 and 2 respectively.
