I'm not sure where the other answer came from, but based on what I learned in my chemistry class, it is dependent on what atom the hydrogen is bonded to. The more electronegative the other atom, the more the electron density is pulled away from the hydrogen, making it behave more and more like an ionic bond instead of a covalent bond. This is referred to as a polar bond. Other factors also come into play, including the size and structure of the rest of the molecule, but the electronegativity of the other atom is the primary factor in whether a hydrogen can be acidic. The polar bond allows for the hydrogen (often referred to simply as a proton, since it won't have an electron with it) to be donated to another molecule that would result in a more favorable, stronger bond. This is the nature of an acid-base reaction.
An example can be seen in Acetate (CH3COOH) which has three hydrogen-carbon bonds, which are non-polar and non-acidic, as opposed to the single hydrogen-oxygen bond on the other end, which is very polar and also acidic.
Note, that there are specific molecules that dissolve completely in water, and where the hydrogen behaves pretty much exactly like an ion: the strong acids. There are seven of these (HCl and HNO3 for example) and this is largely due to the solubility of the conjugate base (what's left after you take off the hydrogen).

∙ 10y agoHyrdogens can be acidic, basic or neutral. The acidic hydrogens have a lower pH level and are very caustic to the the environment. The alkaline based are gentle to the environment.

How many hydrogens are in the molecular formula C22H ClN2O2?
23 Hydrogens.
How many hydrogen atoms are in 3H2SO4?
There are two hydrogens in H2SO4. So there are six hydrogens in 3H2SO4.
Is hydrogens electron shielded from its nucleus?
no
How many hydrogens would bond with silicon?
4
Why farmers need to know how acidic or basic the soil is before they plant their crop?
Different species of plants require different levels of soil pH.
Why is SO3 acidic?
Because it is a lewis acid. It can accept a pair of electrons
Is methane acidic?
No it is not acidic. It is a neutral compound
In butane which hydrogen is more acidic hydrogen of ch3 or hydrogen of ch2 and why?
In butane NONE of the 10 hydrogen atoms are acidic hydrogens (at least not in water) so you can NOT specify which ones are more (or less) acidic.
Why is the pka of fluorenone different that other ketones?
9-fluorenone is different because it is a ketone with all of its carbons tied up in double bonds. There are no readily available acidic hydrogens, therefore this makes the pka of the molecule much greater than most other ketones.
What is a long chain of carbon atoms with hydrogens attached and ending in an acidic group -COOH would be an?
Amino acid
What is the pH of powdered sugar?
pH is dependent on concentration, so the question is meaningless. Sugar solutions, where it does make sense to ask about the pH, are going to be darn close to 7 (possibly very slightly on the acidic side due to the alcoholic hydrogens, but not much... they're alcoholic hydrogens, not acidic ones).
What causes the change of a litmus paper color?
Litmus contains organic chemicals that have a particular colour (some kind of red) when protonated - that is, in acidic conditions - but a different colour (blue) when in basic conditions or when they have donated protons. We see this colour change and can identify whether a solution is nonacidic or nonbasic by using one of these strips.
What are alpha hydrogen how you can identify acidic hydrogen in a compound?
In organic chemistry, alpha hydrogen is attached to the carbon next to the functional group, for example, all the hydrogens on the carbon in CH3OH are alpha-H. We can identify acidic hydrogen by noting all those hydrogens which are either attached to an electronegative atom or any other atom which has a partial positive charge and thus starts pulling the bond electrons.
What is the chemical formula of the formic acid?
The chemical formula of formic acid is HCO2H or HCOOH. In this formula, the two hydrogens are not written combined as H2CO2 to distinguish the acidic hydrogen from the non-acidic hydrogen. Formic acid has only one acidic hydrogen and it is the one is that is attached to the oxygen. The hydrogen that appears first in the formula is not acidic. Pushpa Padmanabhan
Are the hydrogens on the methane molecule different from each other?
No, except for the rare case that one of the hydrogen atoms is a different isotope they are identical.
How many hydrogens are in the molecular formula C22H ClN2O2?
23 Hydrogens.
What are the acidic hydrogens in salicylic acid?
The OH group bonding with the carbonyl group has a pKa around 5, and the OH group connected ortho of the carbonyl group has a pKa around 10. Added correction: Salicylic acid is a monoprotic, not a diprotic acid in water. From wikipedia table value: pKa 2.97
