one with these soft a sergeant in solid on its properties change. david is caused some important properties off so you shuns quantitatively. i know what come to scan basics topic today classic as solutions how the solvents and solutions different.
00:25
before the start of the actual topic a note about the concentration of solutions if the dissolve one mole of shogun one kilogram of water we have a solution off more leyritz you won there are one mole have to solve particles in one kilogram of water.
00:46
the so-called colleague eighty properties the pan on this very number of to solve particles no matter what nature of the party. so when you compare an electrolyte solution the solution of assault we have to take into account the sod to sow seeds have a moat off table salt reduces c eight in so you shun to one mole of particles that and and and nine the number of to soar particles as to why.
01:16
is the amount of sod use the relation between actually to solve particles and originally dissolved amount of substance is called than top factor i order to quantify the number of particles in the specification of concentration the so-called are similarities.
01:36
and are smaller t. were introduced.
01:40
the table salt solution the cell line has a mortality of point five by than all small ality have won the solution therefore contains as many as all particles as the sugars ocean discussed above the two solutions are equal in our small levity.
02:01
the two zero emissions are as a town accordingly we get the of small area team from the malaria the by multiplying by the bank toff fact the simple solution contains two components solent a and solid be depending on how the in the action.
02:21
was between these components are the distinction is made between idea and non idea solutions if we mix to chemical you very similar components the end of the of the mixture corresponds exactly to the end for peace of the study materials there is no and a p of mixing no week.
02:41
of mixing. we're talking about ideas or lucious the so-called floyd hard in school efficient car equals the euro however the two components are energetic early appealing or unappealing he is released or heat is consumed when mixing neither solutions mesa show a negative of players.
03:03
to florey hard and score fish third have guns come to an amicable he analyze the mixture of two components depending on the magnitude of the intra component and the in cash component in the actions the mixture is the the ideal economic or and obama expressed by the lorry hard and.
03:23
a patient high the theory arrival equation that can be used to calculate and the p two p. and free energy of mixing. the following explanations applied to ideas solutions that is pollution and in which intricate opponent and into component in the actions are similar high this year in this p.t. face iran we see a way for pressure curve of matting pressure cuff and the river point of sauven marked in red.
03:53
but the corresponding curves for a solution are drawn in green according to routes first law of the way the pressure of a solution is or was lower than the vapor pressure of solve liquid boys when it's we were precious equal who external pressure however a solution has a low of a proper.
04:13
as the same temperature expressed by routes first law dust in order to board a solution they have to further raise the temperature.
04:21
the lucian exerts a high of boiling point that the pure saw didn't expressed by this equation case up the be is the evil years copy constant a characteristic of every sort of water these constant is approximately two point five kevin's kilogram from old.
04:41
this means that an it solution of all small ality won like the show god sought solutions in our examples where have a boiling point of one hundred point five centigrade a solid freezers one liquid and solid have the same way of oppression.
05:01
that is at a temperature whether weight of pressure cough and the sublimation pressure cuff into said. in the case of a solution this intersection is shifted to lower temperatures there is a so-called freezing point depression office solution compared to the solent expressed by this equation also known as our second law the constant case.
05:29
up c.r. is a cruel scapa constant another characteristic for ever saw them for water chris copy constant is one point eight six skeletons kilogram promote this means that any association was awesome olotu on like the isotonic sugar and salt solution an hour.
05:50
like the others both freeze at negative one point eight six said a solution or was has a lower weight of fresh other m'sawgan which means that the solution is more stable of them for them.
06:05
separate the solution and a solvent by as some have come a bill membrane then saw the molecules bill one tower the move into the more concentrated so you sure this will create an additional pressure in this solution this transfer process.
06:25
used until the pressure and those who should have become so high that the stability in both places is identical again the addition of pressure which shows up in the more concentrated so you shun scarred your smart expression according to fend off who can collaborate from malaria tea and the gas concert.
06:46
and temperature this commercially available cell lines solution within all small aridity of point three most per kilogram shows and as more the pressure off point seven six make up for scotus this is exactly the us more to pressure of human blood so these solutions are used in asia.
07:06
governors therapy since many biological son and brains are some and pam album of what pressure played a major role in biology. body fluids should be isotonic otherwise us could be damaged in hyper tonic media says may lose water very quickly and die this also means that no regular marker organism will survive in a concentrated solution that's why the debts he got its name was moses ten.
07:36
also be reversed by applying a sufficiently high pressure a solution can be kind of i prefer created and turned into the salt that's how sea water his cd in his own nation plants.
07:50
what's more the pressure freezing point depression and boiling point elevation our colleague eighty properties the magnitude of which the pan only on the number of to solve particles are not on their chemical major therefore the properties are well suited to determine mowlam masses of the source.
08:10
composites for example or smaller to is used to determine them work to the masses of proteins and plane that summarize the economics of mixing can be described according to the theory of florida i once with so-called idea solutions there is no heat of mixing and the programs cost efficient car.
08:30
he has zero. the solution also a lower weight of pressure other the pure salt which have become acquainted with the robbers frost law as allusion has both a higher boiling point and a lower freezing point than the pure solved.
08:45
the property is mentioned. our colleague eight year which means only the number of to solve particles is to size if not the chemical nature of the saudi us more to pressure is another colleague a to property it can be calculated using been toxic wage and and especially plays an important role in biology more information.
09:08
about the topic a fine book and of lecture fame fortune and.
