Follow reaction in which let oxidizes in tow pp two plus and it is present in the one Mahler solution, while the copper two plus iron present in one and two tenders for minus for model solutions reduces to see you and this reaction led oxidizes toe people two plus air. It released two electrons, so it's oxidation is 0.14 world while see you two plus can the electrons reduces to see you in? It's a cooperating. It's reduction potential is 0.34 world. Combining the two equations. We will get that PB react with C U two plus forming B B two plus and copper. He not off the cell is equal toe zero point 47 world No to write the e to determine e off the self, which is equal toe e not off the cell minus 0.592 Divide by N. Log Off you, we're log up. Q Is equal toe concentration off the product, which is the concentration of the Leadon divide. By concentration of the reaction which is the concentration of the copper, so s l will be equal toe energy were in art 0.47 Work minus dividing 0.592 divided by because here and is equal toe to 0.59 to divide by two and log up. You putting the value of the legs, which is equal toe. One. Moeller and the copper concentration is one and two. Tennis poor minus four Moeller. So it is equal to 0.47 world minus 0.0 296 When we divide 0.592 by two, it is equal to 0.296 We're log up one Moeller divide by one and two tennis par minus four is equal to four. Multiplying these two values and subtracting from the 0.47 world and we multiply these two value it is equal to 0.1184 When we subtract thes value, it will be equal toe Seattle applying 35 one six world This is he up the cell now. In the second case, we have given that he off the silly zero. So what will be the concentration off the copper iron we have to determine and the concentration of the lead iron we will not change. It will be equal toe one Moeller putting this condition in the equation so we can like that easily is equal toe in Not off the cell, minus 0.59 to where n is equal toe to and log up. Q. Is equal toe the PV two plus concentration divide by See you two plus concentration so easily. Zero. We're in our cells. Zero Applying 47 world minus 0.59 To divide by two is equal to 0.0 296 and we can write this in the farm up. Log up the lead concentration is one Moeller plus Log up the sea you to less concentration, taking this value to the right side. You can also write minus zero point 47 World is equal to minus zero point 296 0.0 296 Log up. One model is equal toe. Zero less. Log up. See you to less concentration. No, we can cancel the negative sign on either side. Zero point Paul say one word is equal toe. When we multiply this value, it will be equal to zero plus log up. See you two plus concentration. We can also write question and this form they'll see you took less. Concentration is equal to taking log to the second side we can write it is the former empty log up zero applying 47 What? So the concentration of the C U two plus I am is equal toe when we take anti log. So this is equal toe two point 95 model. This is the required solution to this part of question. If the concentration of the copper ion is 2.95 models, then Essel will be equal to zero. This is the answer to the past part where this is dance second part, yeah.
