Explain, in terms of ions, why the ability to conduct an electric current is greater for the
solution in beaker 4 than for the solution in beaker 1.

In terms of ions, the ability to conduct an electric current is greater for the solution 4 rather than solution in baker 1 because There are more ions exist in beaker 4
This cause a higher concentration of ions in beaker 4 which lead to better electic process

hope this helps
