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.)
Ketones are acidic in nature because they contain a carbonyl group, which can release a hydrogen ion (H) in a chemical reaction, making them acidic.
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.
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.
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.
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.
Sulphate compounds are compounds that contain the sulfate ion, SO42-.
Carbonated drinks are acidic and contain the ion carbonate (CO3)2-.
Ketones are acidic in nature because they contain a carbonyl group, which can release a hydrogen ion (H) in a chemical reaction, making them acidic.
This is true. Generally an acid is considered a substance that releases a hydrogen ion (H+) in solution or gives one up to another molecule or ion. However, not all hydrogen compounds will release a hydrogen ion. Hydrocarbons (such as methane, CH4 and benzene, C6H6), compounds of carbon and hydrogen, are generally not considered acidic. Some hydrogen compounds are basic, meaning that they produce hydroxide ions (OH-) in water or accept a hydrogen ion from another compound. Examples of basic include ammonia (NH3), potassium hydroxide (KOH), and sodium hydride (NaH). Sodium hydride actually contains the hydride ion (H-), which is highly basic.

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.
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.
No. There are no known compounds containing anionic calcium. Most of the compounds of Ca contain the Ca2+ positive charged ion.
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.
Salts are the products of a neutralization reaction; they contain a positive and negative ion.
