Give two differences that you would observe in the electrolytic cell if copper electrode was made the anode and graphite electrode was made the cathode

1.E0cell = E0cl2 / cl- + E0I- / I2 .2. In given cell Cl2/ Cl- is cathode

Most often used pH electrodes are glass electrodes.Typical model is made of glass tube ended with small glass bubble. Inside ofthe electrode is usually filled with buffered solution of chlorides...

Why graphite is poor than diamond? Graphite and diamond are both made from carbon, which has 4 electrons in its outer shell. Diamond has four bonds, meaning there are no...

The lead acid battery uses lead as the anode and lead dioxide as the cathode, with sulfuric acid as the electrolyte. At the anode: Pb + HSO4- → PbSO4 + H+ + 2e-At the cathode: PbO2 +...

It's the same reason why 0 on the Celsius scale coincides with the melting point of water - we need a common baseline against which we can compare the temperature...

2Cu2O + Cu2S -> 6Cu + SO2n= m/Mn(Cu2O)= 250000g/143.09g/mol= 1747 moln(Cu2S)= 129000g/ 159.16 g/mol= 810.5 molFind limiting reactant: compare1747/2 and 810.5873.5>810.5, consequently , Cu2S is a limiting reactant.According to equation...

Al0 -3e- = Al3+ Cd2+ + 2e- = Cd0E0cell=E0red−E0oxid.

Salt bridge - an ionic bond between the COO- groups of aspartic or glutamic acid and the NH3 + groups of lysine or arginine, the length does not exceed 3.5...

Sn+4 + 2e- ---------Sn+2(reduction half equation)Fe+2 ----------Fe+3 +e- (oxidation half equation)Balancing the equation we have;Sn+4+2Fe+2---------Sn+2+2Fe+3The Fe+2 is the anode because oxidation takes place there while the Sn+4 is the cathode...
