Silver can be plated out of a solution containing silver hyr and ag plus.
00:07
Okay.
00:09
According to the r -reaction, akers plus e minus to produce silver solid.
00:19
So this is the platin reaction.
00:22
The question says how much time in minutes does it take to plates 12 grams of silver? number, this is the mass, and the current, which is i, is 4 .9 hamper.
00:40
Okay, so we are looking for time here.
00:51
Okay, so from this equation, first thing we have to do is to convert this 12 gram to number of moles.
01:00
So number of mole, we know is mass divided by the molar mass.
01:05
And silver, if i'm correct, the atomic mass of that is 1 .08.
01:15
Yeah, 08.
01:22
So therefore, number of mole will be 12 grams, divided by 1 .0 .8 grams for more.
01:30
And that will be 12, however, 108.
01:35
So that will be 0 .111 .1.
01:40
1 mole.
01:44
So, from this equation up here, we know 1 mole of silver requires 1 more of electron, right? 1 more of silver higher requires 1 more of electron who produce 1 more of silver solid.
02:03
Okay.
02:06
So, we can say to produce 1 more of silver solid, we're going to need 1 more of electron.
02:20
So one more of electron will produce one more of a g solid, right? therefore, 0 .111 more of silver solid, we need 0 .111 .1...
