When dissolved in water produces three ions namely;
and
which acts as best conductor amongst the given choices.
Next is potassium bromide when dissolved in water generates only two ions which are and
and acts as an conductor.
Benzoic acid , is a weak acid and is slightly ionized so it acts as an weak conductor.
Sugar is a non ionized compound so it is anon conductor.
Given :
Rate = 75 m 1 s×60 s 1 min×1 h 60 m.
To Find :
Correct answer after conversion.
Solution :
We know, 1 min = 60 sec.
1 hour = 60 min = 60×60 sec = 3600 sec.
Putting value of min and hour in seconds , we get :
Hence, this is the required solution.
