no
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").
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.
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
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).
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.
It is not true; hydrids or hydrates etc. are not acids.
False. In order for a compound to be acidic, it must have contain hydrogen atoms that are ionized in aqueous solution. Not all hydrogen atoms in compounds behave this way. For instance, the organic compound methane contains hydrogen but is not an acid. Ammonia also contains hydrogen, but it typically acts as a base, not an acid.
Hydrogen atoms and produces hydrogen ions when dissolved in water.
Neither - try for an amino acid.
Is Hydrochloric acid HCL is a compound. Hydrochloric acid is a solution of hydrogen chloride in water.
A molecule of the compound sulfuric acid - H2SO4 - contains the elements hydrogen, oxygen and sulfur. There are two atoms of hydrogen, 4 atoms of oxygen and 1 atom of sulfur.

Hydrogen is found in many different compounds. Ammonia is a compound of nitrogen and hydrogen. Methane is a compound of carbon and hydrogen. Petroleum is a more complex mixture of compounds of carbon and hydrogen. Sugars and starches are compounds of carbon, oxygen, and hydrogen. Protein is composed of carbon, oxygen, nitrogen, sulphur, and hydrogen. Every acid (hydrochloric acid, sulphuric acid, prussic acid, etc.) contains hydrogen. Soap contains hydrogen. And lots of other compounds as well.

There are many compounds with oxygen and hydrogen. The most trivial is water, H2O. Also, every acid contains hydrogen, and if they contains oxygen too, they are oxo-acids. Examples: Hydrogen-peroxide: H2O2 Halogenide oxo-acids: HOF HOCl HOBr HOI Sulphuric acid, H2SO4, and sulphite acid, H2SO3. Nitric acid, HNO3, and nitrous acid, HNO2. Phosphoric acids: H4P2O7, H3PO3, H3PO4. Also, there is a lot of organic oxo acids. Every alcohol contains oxygen and hydrogen, every phenol, aether, carbohydrate contains them too.
Neither - try for an amino acid.
No, these are two different chemicals. Hydrochloric acid, or hydrogen chloride, is a compound of hydrogen and chlorine. Sulfuric acid, is a compound of hydrogen, sulfur, and oxygen.
Phosphoric acid contains no carbon and is therefore an inorganic compound.

Yes, hydrochloric acid is a compound of hydrogen and chlorine.
All Arrhenius acids contain hydrogen. From the name, you can tell that Carbon is in it. The suffix "-ic" means that it contains Carbonate, a compound of Carbon and Oxygen.The formula for Carbonic acid is H2CO3, which means that it contains Hydrogen, Carbon, and Oxygen.
When the compound produces hydrogen atoms, (H+) in the solution, it is called an acid.
