Acids are the substance which can donate  Hydrogen ions in solution or the substance which accept electrons . But now the question is how to know which acid is more acidic and which one is less .    For this you have to understand that Strong acid can easily donate H+ This state is valid for the molecules having Hydrogen atom in their molecules . acidic order/ Strength of halogens ( Hydrogen halides ) Hydrogen halides are the molecules having hydrogen and halide group(Fluorine , Chlorine , Bromine and Iodine ) .Bond length between Hydrogen halides increases down the group due to increase in the size of halide atom .  Increasing order of bond length : HI >HBr >HCl> HF Due to increase in bond length , bond strength become weaker down the group . Order of Bond strength : HF >HCl >HBr> HI It means that Hydrogen Iodide(HI) can easily donate proton ( due to weak bond ) into the solution and therefore it is most acidic hydrogen halide  whereas Flouri...

Which is the most acidic compound or Substance ? This question is difficult to answer because for this we have to find the acidic strength of all the compounds which are found or exist in nature..But don't worry , we have answer for this question.. First understand which compound is called as  acid Acid are those compound which can easily donate their H+ ion , easily accept an electron pair and show high resonance stabilization .  All this points have to consider while determine the acidic strength of a compound. After considering all this factors , it has been found that the most acidic compound is  Fluoroantimonic Acid . It's also considered as a Super Acid .  Super Acids are acids with acidic strength or acidity greater than 100% pure sulphuric acid Fluoroantimonic Acid is an inorganic  compound having Chemical formula H2SbF7.It is  prepared by reacting Hydrogen Fluoride(HF)and antimony pentachloride(SbF5) in 2 : 1 ratio . It is 10 quadrillion times m...

Acid can be found in your household Substances. In this post I have show some acidic household Substance with their acidic strength . Before going to the list of acidic Substances, We must know what actually acid is !! Acids are the Substance which can easily donate their H+ ions . This statement is only valid for Substance containing Hydrogen(H) then what about other Substance which doesn't contains H+ ions and still acidic.. So here is another statement : " Acid are the Substance which can easily Accept electron pair . They are generally electron deficient species. Now , Check out some Important Acidic household Substances with their Acidic values . ◆ Shampoo  ◆ Lemon / Orange ◆Milk or other dairy products ◆Coca-Cola / Soft drink ◆ Vinegar ◆Phenol Acidic nature of a Substance can be determined by using pH scale . For a Substance If the pH value is less than 7 then it will be acid , if more than 7 then it will be basic and if exactly 7 then it will be neutral in nature . Let...
