Explain what are the reactions happen at the negative limit

Reference no: EM13271684

Glassy carbon electrode and Platinum electrode are tested in both Sulfuric acid(H2SO4) and Phosphate buffer(KH2PO4,K2HPO4).

1. What are the reactions happen at the negative limit.

2. Why is the negative limit in a given medium always more positive for platinum than it is for glassy carbon?

Why is the negative limit for a given electrode always more positive in the dilute acid than it is in the phosphate buffer?
