Is every compound that contains hydrogen an acid?

Answer 1

no

Answer 2

Second Answer:

Yes, every acid has hydrogen. Most acids are sour, corrode metal, and has hydrogen in it. Bases taste bitter and feel slippery.

Litmus paper is one of the most common acid-base indicators. Litmus paper comes in red or blue. Red litmus paper will turn blue in a base solution. Blue litmus paper will turn red if it is placed in an acid solution. If neither type of litmus paper changes color, the solution is neutral.

First Answer:

It depends on what you mean by "acid." There are several different systems of definition.

The two most commonly used are probably the Bronsted-Lowry definition (which requires that an acid contain at least one hydrogen, since it defines an acid as a "proton donor") and the Lewis definition (which does not require the acid to contain hydrogen, as it defines an acid as an "electron acceptor").

Answer 3

(Yes, they do...)

Most acids do, but we have also Lewis Acids(and bases). 'Normal" acids splits a H+ into solution who is responsible for his accidic nature.

A Lewis acid is capable of accepting a lone pair of electrons(to form an adduct) without releasing a H+ ion.

Theoreticly is a H+ ion also a Lewis acid because the only thing he does is to accept a lone pair electrons to, the only difference is that 'normal' acids are ionic compounds and split as they go into solution.

Answer 4

No, its not true. This is true that all the acids contain hydrogen independent of whether

they are weak acid or strong acid. But bases also contain hydrogen like NaOH, KOH etc.

Also, neutral substances like water also contain hydrogen

Answer 5

Yes, all acids (according to Bronsted/Lowry) contain hydrogen.

A Lewis acid needs no protons in its structure, accepting an 'electron pair' from a (Lewis) base is enough to be 'acid'.

Examples:

Al3+ in AlCl3 : Cl- + AlCl3 --> AlCl4- or

Al3+ in Al(OH)3 : OH- + Al(OH)3 --> Al(OH)4-

(Cl- and OH- are Lewis bases).

Answer 6

No, not every compound that contains hydrogen is an acid. For a compound to be considered an acid, it must be able to donate protons (H+ ions) in a solution. Many compounds containing hydrogen, such as hydrocarbons, do not exhibit acidic properties.

Answer 7

I think only if the H is in the beginning like HCl (hydrogen chloride) because OH (hydroxide) is a base. H2O (water) is an exception since the pH is neutral.

Answer 8

It is not true; hydrids or hydrates etc. are not acids.
