electrochemistry Electrolysis of aqueous lead

2021-6-5  When going through one of my chemistry textbooks, I saw that the electrolysis of aqueous lead nitrate led to oxygen being formed at the anode and lead being formed at the cathode. However, in school, I was taught that only metals less reactive than hydrogen will form at the cathode. This electrolysis contradicts what I learned, as lead is more

2008-7-1  The influence of the concentration of nitrate in the range between 100 and 62,000 mg L −1 NaNO 3 in NaCl solutions was studied under constant potential electrolysis at −2.8. V vs. Ag/AgCl.. The rate of the reduction follows Langmuir–Hinshelwood kinetics, according to which zero order kinetics is followed at concentrations higher than 0.3 M whereas first order at lower concentrations.

THE ELECTROLYSIS OF SOLUTIONS chemguide

2020-8-14  Metals from, say, lead to zinc in the electrochemical series are more complicated. What you get depends on the concentration of the solution. If the solution is reasonably concentrated, you will get the metal deposited. If the solution is verydilute, you will get hydrogen.

Identifying the products of electrolysis Experiment

Once copper(II) nitrate has been electrolysed (preferably last), a deposit of copper will have formed on the cathode. This has to be removed before the cells can be used again. Immersing the plated part of the electrode in a small quantity of 50% concentrated nitric acid (CORROSIVE) in

17.7 Electrolysis Chemistry

In galvanic cells, chemical energy is converted into electrical energy. The opposite is true for electrolytic cells. In electrolytic cells, electrical energy causes nonspontaneous reactions to occur in a process known as electrolysis.The charging electric car pictured in the Chapter 18 Introduction at the beginning of this chapter shows one such process.
