Rank the following solutions in order of decreasing [H3O^+].
.10 M HC2H3C2
.10 M HC6H5O
.10 M HF
,10 M HBr
I think the correct order is: HBr>HF>HC2H3C2>HC6H5O
am i right?
Is that first one a typo and HC2H3O2 is correct? Is the second one phenol? Assuming both of those are true I think the order is correct.
The first one should read HC2H3O2. yes the second one is phenol
Yes, you are correct! The correct order of decreasing [H3O^+] is HBr>HF>HC2H3C2>HC6H5O.
To rank the solutions in order of decreasing [H3O+], you need to consider the acidity of each compound and the dissociation of H3O+ ion in water.
First, let's look at the compounds in order to determine their acidity:
1. HC2H3C2: This is acetic acid, a weak acid. It partially dissociates in water, releasing H3O+ ions.
2. HC6H5O: This is phenol, which is also a weak acid. It partially dissociates in water, releasing H3O+ ions.
3. HF: This is hydrofluoric acid, a weak acid. It partially dissociates in water, releasing H3O+ ions.
4. HBr: This is hydrobromic acid, a strong acid. It completely dissociates in water, releasing a large number of H3O+ ions.
Based on the strength of the acids, we can determine the relative concentrations of H3O+ ions in the solutions.
Therefore, the correct order of decreasing [H3O+] is:
HBr > HF > HC6H5O > HC2H3C2
So, your answer is incorrect. The correct order is HBr>HF>HC6H5O>HC2H3C2.
