Double displacement reaction | Chemical reactions and equations | Chemistry | Khan Academy

In double displacement reaction, the ions of the reactants exchange position. This could be used to make volcanos for science experiments.

This man is a very intelligent person. I feel good to know such talent and fluency still exists. I love his videos. Keep going!!!

[@Nikhil-tb8bo]

Thank you so much , I was looking around from so long for clear explanation of this but everywhere it was just bookish explanation, I think this is the only person knowing the concepts in depth.

[@joshranya8976]

Super explanation sir 🎉🎉

[@sameermulla7310]

Good telling

[@AumAgrawal-re3ze]

Please combine all videos of one chapter to simplify the things

Very good explanation of doubledisplacement reaction

[@aloneboy5109]

There are so many general formula's buy didn't match. But this actually works and fulfill everyone's need

[@neelamadhavan7743]

Very intresting

I am waiting your chemistry videos in hindi...

[@uniquegaming8093]

Bro why Hindi when you know how to type in english

Why don't Sulphur and Chlorine react to form a covalent bond then ?

[@Scorpion-nk9xh]

maybe because it is easier to get attracted to the positive ions in solution

[@xian-georgereid9612]

I have one issue with this video. the 'HOH' should not represent water like that since the ionic forms are being used, hence it should be H2O to show that the valencies are exchanged as well

So I've learned about single and double displacement reactions but I was thinking if triple displacement is possible? If yes! then how is it decided which element displaces the other??? when there are two metals the element can displace???? I was trying to find out about the same and I came across an equation: 2 AgNO3 + 2 NaCl + K2CrO4 → Ag2CrO4 + 2 NaNO3 + 2 KCl what type of reaction is this??? But why did Silver, in the above equation displaced Potassium and not Sodium?? How is it decided who displaces whom??? Please help!!!

[@P.S9999]

If you want only the displacement of metals you need to know about metal reactivity series. As in single displacement reaction only one ion is displaced here 2 will replace each other depend how reactive one elements ion is. So you need to check the metal reactivity series to decide which element replaces another element the more reactive metal will always replace less reactive metals. Hope it helps :)

thank u so much

[@legoholic230]

wait i am confused the first example he gave of double displacement is an acid reacting with base but it wont form HOH cuz acid + base always gives salt +water?

[@janhavikatakdhond2196]

One thing in the following reaction is it possible OK to write (nacl)2 + BaSO4 Question was Na2S + HCl -> 2NaCl + BaSO4 Please give the answer if you know :)))

[@FarhanKhan-vr4mf]

This equation is totally wrong as in reactant there is no barium but in product. Instead,barium sulphate [Ba(SO4)]there should be h2s. As discussed in video also.
