Answer:
The cathode is the electrode where the reduction takes place.
Explanation:
Cell has three components:
an electrolyte and two electrodes which is a cathode and an anode.
Electrolyte is usually solution of the water or other solvents in which the ions are dissolved.
<u>In electrolytic cell:</u>
Negatively charged electrode is the cathode where the process of reduction takes place.
Positively charged electrode is the anode where the process of oxidation takes place.
<u>In galvanic cell:</u>
Positively charged electrode is the cathode where the process of reduction takes place.
Negatively charged electrode is the anode where the process of oxidation takes place.
<u>So, the correct answer is - The cathode is the electrode where the reduction takes place.</u>
Answer:
3.25 L
Explanation:
A 2.0M solution of HCl will have 2 moles of HCl for each liter of solution. 1.5 liters of 5.0M NaOH has a total of 5*1.5=7.5 moles of NaOH. Therefore, you would need 7.5/2=3.25 liters of HCl. Hope this helps!
