(b) Do all voltaic cells produce a positive cell potential?

Video transcript

Hey everyone. So here it says, identify the incorrect statements below. Reduction occurs at the a note of the galvanic cell. Alright, so let's unpack this to remember the sights of reduction and oxidation. Just remember red cat and an ox. This means reduction happens at the cathode and at the anodes there's oxidation. So here this statement is false. Reduction occurs at the cathode. Now, galvanic cell is just a spontaneous electrochemical cell, but it doesn't matter if it's spontaneous or not. Cathode is where reduction always happens. A node is where oxidation always happens. The type of electrochemical cell is irrelevant. Right next. The self potential is temperature dependent. Uh that is true. Uh temperatures can cause a fluctuation in your self potential, especially if there are gaseous species involved. Because remember, increasing the temperature can cause some of those gas particles to leave the solution, thereby changing the pressures involved. And this itself could have an effect on our self potential. A functioning galvanic cell, also known as a voltaic cell has a positive E. M. F. That is true. So a galvanic cell or voltaic cell is a spontaneous sell. It possesses a positive E. M. F. Or cell potential. So here, the only choice that's false is option a
