Answer:
Usually one wants to keep track of the amount of the solute dissolved in the solution. We call this the concentrations. ... Molarity (M) is defined as the number of moles of solute (n) divided by the volume (V) of the solution in liters.itauuajajjajajajjsbsvcvsv
Answer:
The thick rod of impure copper plate is to be attached to the positive terminal of the battery because when electric current is passed through the copper sulphate solution, it gets dissociated into copper and sulphate. The free copper, being positively charged, gets drawn to the negative terminal of the battery and gets deposited on it. On the other hand the loss of copper from the solution is regained from the impure copper rod which is attached to the positive terminal of the battery.
