Question

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

Answer 1

Explanation :

Voltaic cells are an electro chemical cell in which chemical reactions occurs to produce electrical energy. Its parts are :

(i) At anode oxidation occurs.

(ii) At cathode reduction occurs.

(iii) A salt bridge.

(iv) External circuit.

(v) Load.

Suppose a voltaic cell is made up of $ZnSO_4$ and $CuSO_4$. Here zinc can lose electron more rapidly as that of copper. Oxidation of zinc occurs and is called as anode. So, this is a negative terminal.

On the other hand, copper receives electron and hence become cathode. So, this is a positive terminal.

Hence, electrons flow form Zinc to copper i.e. from negative terminal to positive terminal.

Answer 2

Answer:

^ Shirleywashington is correct. The rating of her answer is misleading, but the answer is negative to positive.
