Question

Beryllium is placed above magnesium in the II group. Beryllium dust, therefore, when added to $MgC{l}_2$ solution will:

• A. have no effect
• B. precipitate $Mg$ metal
• C. precipitate $MgO$
• D. lead to dissolution of $Be$ metal

Answer 1

The correct option is A have no effect

$Be$ is above $Mg$ in a periodic table but it is below $Mg$ in the electrochemical series. So, $Be$ is less reactive than $Mg$ and there is no effect in the solution.
