is HF a stronger acid than HCL ?expain.?

Answer 1

HCl is a stronger acid than HF!

HCl has more ionic character than covalent character.
If the atom bonded to the Hydrogen is larger in size than the acid will be stronger.(due to difference in polarity of the compound)

If the acid is more polar it dissociates to a greater extent when present in a polar solvent like water.
HCl dissociates almost completely,whereas HF dissociates partially and hence HCl is a stronger acid then HF.

Also from the point of view of Hydrogen bonding HF exhibits the strongest hydrogen bonding with itself and with water ,which is why dissociation is further weakened than HCl.

HI is the strongest among the hydrohalic acids.

Answer 2

HF is a much much stronger acid than HCl. Think of it this way. HF will EAT THROUGH GLASS!. HF has a much shorter shelf life because it becomes contaminated just by sitting in its glass jar. HCl, though strong, does not have the aggressiveness of HF.

Just look at a periodic table of elements. Simple ionic acids get stronger the further right and up you go on the table. Since F is above CL on the table, you can bet on the acid being stronger/more reactive.

Answer 3

HCL is the stronger of the two. HF is a weak acid.

Answer 4

the acid is the one which releases h+ ion readily.HF is a strong acid
because of stronger bond between H and F .because F is more electronegative than any other element that is why HF is a stronger acid than hcl

Answer 5

HCl is stronger. HF only ionizes partially. It is because F is more electro negative than Cl, so holds the H atom stronger than Cl.

Answer 6

HF is stronger. I beleive it is the strongest. It's a superacid

But HCl is close behind it.

Answer 7

yes... F is more eletronegative than Cl, so is more easy the HF liberate a ion H+, than a HCl liberate a ion H+, because the F can stand the negative carg better than Cl
F- is more stable than Cl-

Answer 8

i think HF should be stronger as F is ,more electronegative than Cl , consequently H-----F is weakier than H----Cl bond . but, difinition of a good acid is that which gives maximum H+ ions , so H-----F weak bond breaks easily than H-----Cl bond , thus HF can furnish more H+ ions .
