• Time – how long electrolysation happens for
• Current – how many amps travel to the electrode
• Temperature – effects particles kinetic energy
• Solution – type of ion
• Molarity of solution – mols/cm3 ; number of ions
• Charge of Ions - number of electrons needed to become...
just chemistry coursework. we electrolysed for 2 mins. part of the problem is nothing was kept constant, diffusion wasnt constant because the three 'constants' we had, wernt kept consant. I=nAve , we changed 'e'; charge of electron.
Theres more about my experiment here ...
Im evaluating my experiment. One of the ways i could improve it would to get rid f the effect of diffusion. When i electrolysed my 3 solutions, high concentration of ion areas ( generally in the solution) diffused into low concentratio areas ( around the cathode ), this would be different...
How could i reduce the effect of diffusion of ions in an electrolysis cell. e.g AgNO3 Ag+
Stirring constanly would help? but thats not easily kept fair or constant. Could i replace this idea with rotating electrodes?
Many Thanks, Adam
I have the marked draft of my coursework, its 36/40 but I need to improve 3 things. I need to expand on the Variables I have listed on my coursework, i have done half of them but im having trouble on the others. Heres the vaiables, the bold is what ive added. Any help is much appreciated...
sorry, im starting to get confused here. ive had a crap day learning my coursework is all wrong :L Isnt Tin Sn? but tin-tetra chloride has +4 charged chlorine atoms dosent it? im looking for a +4 solution where the cations are a metal. e.g copper or silver. Ive drawn a blank so far looking...
i have noted a few down, e.g Pb, NH, Ti, they need to be solouble in water. Is there a way of telling form the periodic table what elements can be 4+? is that to do with groups or rows? thankyou
edit : ignore NH, its not metallic
My coursework is ruined, but im not asking for help with my coursework.
Does anyone know if there is a ion with a charge of +4. I might not be making sense. I know about Copper Chloride (CuCl+2) and Silver Nitrate (AgNO3+1) and Iron III Chloride (FeCl+3). Does anyone know of a plus 4?
Im only 15. I know a bit about cancer, but i cant find anywhere how it actually kills you. I understand metastasis; where the cancer spreads. But i dont understand how the growth of extra cells (damaged or not) can kill.
Might be a stupid question.
