Re: Weak Acids
The longer the bond length, the stronger the acid. So, weak acids have shorter bond length because they cannot dissociate as easily in water as molecules (acids) with longer bind lengths.

Re: Weak Acids
Since an acid's strength is a measure of its ability to ionize in solution, an acid with high strength should dissociate very easily. Thus it must have relatively long bonds, where as a weak acid, an acid with a low tendency to dissociate, should have much shorter, stronger, bonds.
Re: Weak Acids
Weak acids means that the molecules do not dissociate, or ionize, easily in a solution. This means that the bond is strong (and therefore shorter) because the molecule will hold onto its H atoms.

Re: Weak Acids
Weak acids have shorter bond lengths because they don't completely ionize in solution, whereas strong acids have weak bond lengths because they completely ionize.

Re: Weak Acids
Weaker acids have shorter bond lengths because in a solution they do not ionize completely.

Re: Weak Acids
Weak acids actually have shorter bond lengths because they don't completely ionize in a solution.

Re: Weak Acids
Weaker acids tend to have shorter bond lengths. Therefore the opposite is true where stronger acids have longer bond lengths. This particular aspect of an acid is highlighted in the fact that weaker acids tend to have a hard time ionizing completely in solutions.

Re: Weak Acids
Weak acids have shorter bond lengths because this makes it harder for them to dissolve in water and produce H3O+

Re: Weak Acids
The strength of the acid is the ability for it to accept electrons. If the molecule is really strong and has a short bond length (like HF) then that would mean that it would be a weak acid.

Re: Weak Acids
The longer the bond length, the stronger the acid will be. This is because the bond is weaker when it's longer, making it easier to break and therefore dissociate and completely ionize, which is a primary characteristic of a strong acid. Conversely, when the bond length is shorter, the bond becomes stronger (making it harder to break) and the acid will therefore be weaker. Hope this helps!

Re: Weak Acids
Weak acids have shorter bonds lengths as weak acids do not dissociate as easily as strong acids whose longer bonds are easier to break.

Re: Weak Acids
Shorter bond lengths indicate that it is a weak acid. Longer bond lengths mean that it will be a stronger acid.

Re: Weak Acids
Weak acids actually have short bond lengths, this is because molecules with shorter bond lengths are harder to break. Strong acids have longer bond lengths which are easier to break.

Re: Weak Acids
Strong acids have long bond lengths. Same applies to weak acids, having short bond lengths, meaning they cannot dissociate easily.

Re: Weak Acids
Weak acids have shorter bond lengths because they less readily give up their proton whereas strong acids have longer bond lengths because they freely give up their proton.

Re: Weak Acids
Stronger acids have longer bond lengths, and weak acids have shorter bond lengths. This is because the weaker acids cannot dissociate as easily as strong acids.

Re: Weak Acids
Weak acids have shorter bond lengths, (like in comparing HF<HCl<HBr<HI from weakest to strongest). Weak acids don't dissociate easily in water and do not produce H+/H3O+ as easily.

Re: Weak Acids
Weak acids would have a shorter bond length, because they are less likely to give up their H+ likely compared to a strong acid, which has longer (weaker) bonds that easily give up H+ protons

Re: Weak Acids
I think stronger acid have longer bonds, because longer bonds break more easily which contribute to their ability to donate a proton and dissociate completely, versus weak acid which only dissociates partially.
Re: Weak Acids
Weak acids have short bond lengths since they cannot dissociate in water as efficiently as acids with longer bond lengths! This bond is held more closely together and i stronger. The acid becomes stronger as the length of the bond increases. The larger the X atom is, the stronger the acid will be and as its electronegativity increases, the acid strength does as well. I hope this helps!

Re: Weak Acids
Weaker acids have shorter bond lengths--they hold on to their hydrogen ions more tightly, so it is more difficult for them to release H+ ions, making them less acidic. hope this helps:)
