A strip of solid magnesium metal is put into a beaker of 0.053M ZnSO4 solution. yes no?

A strip of solid zinc metal is put into a beaker of 0.058M MgBr2 solution. yes no?

Answer 1

Answer:

1) Yes

2) No

Explanation:

A strip of solid magnesium metal is put into a beaker of 0.053M ZnSO4 solution-YES

A chemical reaction occurs

Mg(s) + ZnSO4(aq) ----------> MgSO4(aq) +Zn(s)

This reaction is possible because magnesium is far higher than zinc in the activity series of metals hence magnesium can displace zinc from a solution of a zinc salt.

A strip of solid zinc metal is put into a beaker of 0.058M MgBr2 solution. NO

A chemical reaction does not occur because magnesium is higher than zinc in the activity series hence zinc cannot displace magnesium from a solution of its salt.
