oh wow, i had my chemistry finals today and i watched the videos until here, i stopped watching them and i left for my exam and guess what? i could have solved 2 questions which i did not if i would have looked just this one video! :(
the "fancy font" is just danish and Norwegian letter Ø or ø. It is because Brønsted was Danish pronounced liked the vowel in soeur (sister in french) :)
@someone20ify He did not clarify the spelling in the video, so I wanted to tell everyone who was watching what the correct spelling was - for their own sake.
@someone20ify However, 'disassociate' means 'dissociate', so both MIGHT be accepted. But "dissociate" (what my teachers use) is used more (10.4 mil vs. 975k pages with Google). Wikipedia's article on dissociation does not have 'disassociate'.
@soopa123 The H2O molecule has a lone pair on the oxygen, so the H+ ion will readily react. You only need energy to break bonds, in fact, you need to lose energy in order to make them (in exothermic reactions). The force of the partial charges on the H2O dipole is sufficient to dissociate a molecule, such as HCl into H+ and Cl- (as an example), so no energy is required for such a reaction to take place.
I'm from argentina.I studied english cince childhood but never pay attention in class and now i wish i could understand you :(
A guy here in argentina traslate your videos and i love you way to explain..but still do not had these videos on acids and bases. well thanks anyway..kisses! :D
if my teacher explained it like you do,we would all understand better,I always watch your videos for upcoming exams to understand better,so thankyou..
@rijaa000 HCl is a acid and H20 is a base. The hydrogen in (H)Cl will eventually dissociate into the H20 because both the solution contains Hydrogen, and the main point of the reaction is to dissociate HCl and H20 completely, so the Hydrogen would ionize into H20(H20(water) is an ionizer) forming H30 the product of the reactant. the Cl will be alone in order for the dissociation to occur. The remaining solutions will have a polar + and - sign(positive attracting negative).
You are so totally awesome at explaining this. I feel lost in my biochem class but you really help me understand the concepts. Thank you for taking your time to show us how to understand. : )
aq means aquous. dont know what that means but it sounds like its describing a liquid so i see your point. maybe scientists were drunk when they invented this crap.
@knexfan100 (aq) aqueous means, let's say HCl (written HCl(aq) ) is dissolved in water, it's not 100% pure HCl, it's a solution combined of HCl molecules and H2O molecules . (l) liquid means that that compound i.e. water (written H2O(l) ) is 100% pure water in a liquid aggregate state.
Of course in this case, pure water is only theoretical. We don't use pure water in labs.
@lollmaoroflhahaa Refers to aqueous solution, which is another way of saying water. Aqueous solution only refers to water, not mercury or any other liquid. It's just a more specific way of saying "liquid water."
"Should'nt" you learn how to spell? Why are you correcting such small details like I am correcting your grammar? Does the 'H2O(aq)' detract you from your free lecture on acids and bases? I bet most people know that H2O is a liquid just as most people could assume that "should'nt" means "shouldn't".
@lollmaoroflhahaa No, water should not be liquid because it is in an aqueous solution (it is in water) I know it sounds redundant but technically, you would say that it is in an aqueous solution because that helps you see that it is dissociating. Water in water is an aqueous solution. He is trying to show that acids and bases react in aqueous solutions.
I wish I understood the theory of it all with asid and bases but I guss the reason why after searching I still haven't found it is because it is too complex and is for 2nd or 3rd year students
Very assuring voice intonation. Confident handling of concepts. But it would have been better to make clear---and emphasize---the mechanism of ionization. There's a world of difference in saying that a PROTON was donated to an atom, from saying that an atom has an excess of a positive CHARGE because it lost an electron of negative charge. Understanding that subtlety goes a long way---it's closer to observed phenomena. It's a crucial matter this balancing of electric CHARGES in atoms.
Hi Sal, I owe you millions. You're the master. My text book s-u-c-k-s, for a certainty.
I logged on just to thank you. I watched just about all of your biology videos. Great job. Great work. Wish I had you for all my class time experience. You're the greatest. Signed Love.
@sugarcoatedsour actually, water is an AQUEOUS liquid. However you are correct that water cannot dissolve in water because water is a solvent...so a solvent cannot dissolve in a solvent, only a solute can dissolve in a solvent.
@StraightShotz Water is pure, if it isn't pure then it isn't water. When water is referenced in chemistry it is meant as the pure H2O compound and is therefore a liquid not aqueous.
In the B Lowry Base, it's not that the "Li+ has accepted the fact that it has a proton +" that make it a base, it's that the OH- ion can ACCEPT a proton (H+) out of the solution and make a water molecule - thus it is a proton acceptor.
hcl in h2o is shown but lioh in h2o is not demonstrated . i was expecting to see what lioh +h2o will bring to commit my judgement on oh con increasment . thanks for the hard work .
for my chemistry coursework i'm investigating the effect of the rate of reaction when only the congruent base is increased. When i did the experiment i found that it slows the reaction down as the conc. increases, any1 know why?
yah cool vid..thnks..bt hw do u identify a lewis acid without an equation.. if u r jst given a random chemical like BH3..and no reactant..hw can u tell its a lewis acid

HELLO!!!!!
LiOH -> (OH-) + (Li+) is a "proton donor" reaction according to Lowry.
This reaction also looks like this:
LiOH(s) + H2O(l) => Li+ + OH- + H20 + HEAT
The O in OH has a proton attached to it, the H. Therefore, it donated the proton th the aqueaous solution and produced heat aswell.
