Hello student here the question is given and the question is having the potato piece and these potato peas need to compare with the salt solution.
00:12
So by comparing with this salt solution, how we can know the solutions would be isotonic, hypertonic or hypotonic.
00:25
So we have to tell how we can know the solution should be this.
00:32
So if we want to know this, then we have to compare the concentration present inside this potato piece as well as the salt solution.
00:42
So he suppose here this is the baker or flas where the salt solution is given.
00:50
So this is the salt solution.
00:53
And we put a potato.
00:57
So suppose here we are taking this potato.
01:01
So these potato have all.
01:03
Having the salute.
01:05
So if the salute concentration inside the potato is equal to the salt solution.
01:12
So if the concentration of salute in potato is equal to the salt solution concentration then it is known as isotonic because iso simply means equal.
01:30
So having the equal concentration of the salute in the solution.
01:34
In both the cases so in that case there is no moment there is no moment of water because if the concentration of the salute is the same then the water concentration will be also same so we there is no net moment of water because in case of water moment osmosis is done and the osmosis from the high solute curve so high concentration of water is going to going to move to the low concentration water and this is done by the semi -permeable membrane.
02:14
So here the semi -permeable membrane is this potato piece having the membrane by which the solvent molecule or water molecule going to in or out.
02:25
But in case of isotonic solution there is no movement of water.
02:29
So suppose this is the first case where the solution will be isotonic.
02:34
So in this case there is no.
02:37
Change in size and shape of potato.
02:49
And if they are comparing the second case, suppose this is the c solution and in this solution we have placed this potato and the solute concentration is here the solute concentration is a high and here the solute concentration which is a salt.
03:11
Salt is less.
03:13
So the water will be more here in the salt solution...
