Why 4 hydroxy benzoic acid is less acidic than 2 hydroxy benzoic acid?

as because in 2-hydroxy benzoic acid, there is a possibility of H-bonding which makes the dissociated ion stable and will not combine with H+ ion leaving it free, while it is not so in case of 4-hydroxy benzoic acid.

What is a slightly acidic pH?
An acid pH is anything less than 7 including zero.
If a substance has a pH of 6 is it a strong or weak acid?
Solutions with a pH less than 7 are acidic. Solutions with a pH greater than 7 are basic. Thus, a pH of 6.5 is in fact slightly acidic.
Preservatives such as citric acid are added to foods to interfere with bacterial growth This creates an acidic pH in the food Why does this affect the bacteria that are present?
An acidic environment causes bacterial enzymes to fail or work less efficiently.
Will the pH of a buffer solution be higher or lower than the pH of a weak acid?
The pH of buffer solution will be higher (Less acidic) than the corresponding acid because the common ion effect in buffer mixture suppressed the ionization of acid.
What is a substance with a pH less than 0?
Usually PH's less than 7 are said to be acidic (acids), while PH's more than 7 are said to be alkaline (alkalies). An example of an acid would be HCL Hydrochloric acid (with a PH of -1.0) while Cola has a PH of 2.5
Which is more acidic benzoic acid or acetic acid?
Benzoic acid is the stronger acid compared to ethanoic acid. However, ethanoic acid is more corrosive and will burn skin etc more than benzoic acid. Corrosivity/burn potential are not the same as acid strength. This is due to the delocalisation of the lone pair of electrons on the oxygen atom into the benzene, increasing the polarity of the -OH bond and thus makes the cleaving of the H+ ion easier. The delocalisation of electrons into the benzene ring also stabilises the carboxylate ion. Therefore the position of equilibrium lies more to the right and this shows that benzoic is a more acidic acid. The simplified version is that a benzene ring is electron withdrawing and a methyl group is electron releasing. The electron withdrawing power makes the releasing of the H+ ion easier.
Why Salysilic acid is stronger than benzoic acid?
In salicylic acid the hydrogen atom in OH group have a tendency to form hydrogen bonding with oxygen atom in the COO - group thus leaving the H+ ion freely available. In case of ortho methoxy benzoic acid, the possibility of hydrogen bonding is avoided by the presence of strong -CH3 group. Hence salicylic acid is stronger than ortho methoxy benzoic acid.
Does a base make an acid less acidic?
oo kasi ang base hindi acidic so less acidic na ung acid
What ingredient in soda makes it so acidic?
I think it is carbonate. I think it is carbonate. Cola is basically phosphoric acid (55%) and sugar (10%) which gives it a PH of about 2.6 (similar to vinegar). Soda water is much less acidic but is still mildly acidic from the carbonic acid created when carbon dioxide is dissolved in water. The three(3) acid ingredients in most sodas are (1) carbonic acid, (2) (ortho) phosphoric acid, and (3) benzoic acid; all contribute to "tartness", and the last is a preservative!
What is acid acidic?
acidic acid is the nucleic level found on sodas or cleaning products and do forth. its all acidic but the higher the acidic level is ITS LESS ACIDIC then lower number.
What is a slightly acidic pH?
An acid pH is anything less than 7 including zero.
If you add water to an acid will it weaken the acid?
Yes. It will dilute the acid and increase its pH value (less acidic).
Does adding a base make an acid less acidic?
what do you mean
Is 1-hexanol more acidic or less acidic than phenol?
1-hexanol is an alcohol so it is a neutral compound not an acid while phenol is a strong acid.
Is orange juice acidic or alkaline?
Yes it has acid, the acid in it is Malic Acid.
Is potato a base?
A potato is an acid with the ph of 6.1, on the less acidic side.
Is hydrochloric acid alkali or acidic?
No - acids and alkalis are "opposites". Acids have a pH less than 7 (which is the pH of water which is neutral) and alkalis have one over 7. Sulphuric acid comes in various strengths but often has a pH less than 1 and sometimes one which is negative.
