At least one H+ ion, called proton, and one anion which remains when the proton is donated to a base or to a water molecule: H3O+ (hydronium) is formed, lowering pH of the water.
The above isn't actually wrong, though it's worth noting that that's actually a description of a particular type of acid (an Arrhenius or possibly Brønsted-Lowry acid). Lewis acids use a more general definition and are not required to contain any particular ion... any electron pair acceptor is a Lewis acid. (All Lewis acids are Brønsted acids, but not all Brønsted acids are Lewis acids.)

Which compounds does not contain polyatomic ion?
Compounds like sodium chloride (NaCl), methane (CH4), and water (H2O) do not contain polyatomic ions. These compounds are formed from simple combinations of individual elements without the presence of complex ions.
Acidic compounds contain which element?
Well it depends on what kind of acid you're talking about. Most people think of acids as hydrogen donating compounds and that is indeed one type of acid. It fits under the Bronsted-Lowry definition of an acid and under the Arrhenius definition (which says that acids are compounds that dissociate in water into hydrogen ions etc.). However, under the Lewis definition, an acid is anything that can accept an electron pair and it doesn't have to contain hydrogen.
Is NH42SO4 alkaline or acidic or neutral?
NH4HSO4 is acidic. When dissolved in water, it forms ammonium ion (NH4+) and hydrogen sulfate ion (HSO4-), which can donate a hydrogen ion (H+) to the solution, making it acidic.
Why do monoprotic acidic salts behave as strong acids?
Monoprotic acidic salts contain only one acidic hydrogen ion that can easily dissociate in water, leading to a high concentration of H+ ions in solution. This results in a low pH and strong acidic behavior.
What is the difference between Carbonates and Hydroxides?
Carbonates are compounds that contain the carbonate ion (CO3^2-) and are formed by the reaction of carbon dioxide with a base. Hydroxides are compounds that contain the hydroxide ion (OH-) and are formed by the reaction of a metal with water. Carbonates are typically insoluble in water, while hydroxides are usually soluble.
What are sulphate compounds?
Sulphate compounds are compounds that contain the sulfate ion, SO42-.
What kind of solutions are?
Carbonated drinks are acidic and contain the ion carbonate (CO3)2-.
All acids are hydrogen compounds but all hydrogen compounds are not acids?
Not all hydrogen compounds are acids because acids specifically donate protons (H+) in solutions, while other hydrogen compounds may not exhibit acidic properties. While all acids contain hydrogen, not all hydrogen compounds are capable of releasing protons in solution to behave as acids.

Which compounds contains the lead III ion?
Lead(III) ion is unstable and not commonly found in chemical compounds. However, compounds like lead(IV) oxide (PbO2) and lead(IV) sulfate (PbSO4) contain lead in the +4 oxidation state.
Why do monoprotic acidic salts behave as strong acids?
Monoprotic acidic salts contain only one acidic hydrogen ion that can easily dissociate in water, leading to a high concentration of H+ ions in solution. This results in a low pH and strong acidic behavior.
Does calcium form a negative ion?
No, calcium typically forms a positive ion (Ca2+) because it tends to lose two electrons to achieve a stable electron configuration.
What is the difference between Carbonates and Hydroxides?
Carbonates are compounds that contain the carbonate ion (CO3^2-) and are formed by the reaction of carbon dioxide with a base. Hydroxides are compounds that contain the hydroxide ion (OH-) and are formed by the reaction of a metal with water. Carbonates are typically insoluble in water, while hydroxides are usually soluble.
What are chlorides?
Chlorides are compounds that contain chlorine in the 1- oxidation state. The term usually refers to compounds with the Cl- ion such as sodium chloride. However it is sometimes applied to covalent compounds such as methyl chloride.
How are salts the same?
Salts are the products of a neutralization reaction; they contain a positive and negative ion.
