Golden Rules Of Investment

12 GOLDEN RULES OF INVESTMENT Live by these 12 rules and let your money grow!  1) The past is irrelevant –   Do not rely on past performances and build castles in the air. Invest for tomorrow and live for today.  2) Opinions can hurt. Don’t ask too many people –   just don’t!! To each, his own. What works for someone else, may not work for you and vice-versa. Your investment plan should be as unique as the back of your hand. More importantly, it must suit you best.  3) Everyone’s journey is different. Understand yours. –   Do not invest if you’re not clear on the purpose. Do not draw parallels with other investors. Your need for investing, risk appetite, and nature of investments is of utmost importance. You need to understand what you are doing.  4) Don’t allow your ego to engage with professional advice –   Trust your financial advisor! Google can give you lots of information but your advisor will tell you what’s best for you. Listen and then ...

QUANTITATIVE ASPECTS OF FARADAY'S LAWS OF ELECTROLYSIS


Quantitative aspects of Faraday's laws of electrolysis 

Faraday's first law of electrolysis  
The mass of the reactant consumed or of the product formed at an electrode during electrolysis is calculated by using the stoichiometry of the half-reaction and the molar mass of the substance. 

The following procedure is used in the calculations: 
 
(I) Quantity of electricity passed: 
 The quantity of electricity (charge) passed through a cell is calculated by measuring the quantity of electric current I passed through the cell and the time t of the passage of current. The quantity of electricity Q is given by Q (C) =I (A) x t (s) 
 
(ii) Number of electrons passed in moles:  
The charge of one-mole electrons is 96500 C. 
Hence, number of moles of electrons actually passed = Q(C)/96500 (C/mole-) 
 
(iii) Number of moles of product formed: 
The balanced equation of the half-reaction (stoichiometry) indicates the number of moles of electrons used and a number of moles of product formed. 
From these quantities, the number of moles of product actually formed can be calculated as 
A number of moles of the product formed = number moles of electrons actually passed x mole ratio where mole ratio = moles of product formed in half-reaction/moles of electrons required in half-reaction. 
 
(iv) Mass of product formed: 
Mass of product formed = a number of moles of product formed x its molar mass. 

From the above steps, the following general formulae can be used to calculate the mass of the substance produced. 
(I) Moles of the substance produced =I(A) x t(s)/96500 (C/mol e-) x mole ratio from the stoichiometry 
(ii) Mass of the substance produced =I(A) x t(s)/96500 (C/mol e-) x mole ratio x molar mass of the substance
