is hclo4 an acid or base?

If you see any other acid or base than one of these strong ones it will be a weak acid or base (unless I specifically say otherwise in the problem). The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only).

HCl is a stronger acid than H2SO4 because a proton more easily separates from chloride ion than from hydrogen sulphate ion and this is reflected in their dissociation constants. The lower the pKa value of an acid the stronger it is. The pKa values of HCl and H2SO4 are -6 and -3 , respectively.

We gots hydrochloric acid, the which derives from HCl(g) ... A commercial solution at room temperature has a concentration of approx. ... On the other hand, nitric acid is represented as +N(=O)(OH)O− . The commercial mixture is 68% by mass, which corresponds to 18⋅mol⋅L−1 ...

Ba(OH)2 contains oxygen, but it is a base, not an acid. H3PO4, phosphoric acid, is an oxoacid because it is an acid that contains oxygen.

According to the Brønsted-Lowry acid base-theory, an acid is a proton (hydrogen ion, H+ ) donator, and a base is a proton (hydrogen ion, H+ ) acceptor. Ammonia is the hydrogen ion acceptor, and is therefore a base, and water is the hydrogen ion donor, and is therefore an acid.

Both hydrochloric acid (HCl) and sulfuric acids (H2SO4) are strong mineral(inorganic) acids. But, there are some impotant differences between the two. ... HCl is a monobasic acid, which means its molecule has only one ionizable hydrogen atom. H2SO4 is a dibasic acid, as it has two ionizable hydrogen atoms in its molecule.

For example, HCl is an acid, one of the strongest, because it has an H+ attaches to the Cl-. ... With the knowledge that H+ is needed to make a solution acidic, AgNO3 is not an acid because it produces Ag+ and NO3– ions. Neither is it a base because it does not produce OH-.

Acids are molecular compounds that dissolve in water to produce hydrogen ions and an anion. Bases are ionic compounds consisting of hydroxide ions and a cation. The naming rules for acids are based on the suffix of the anion.

HSO4- is an acidic anion because it tends to donate protons when in pure water. Notice how the first arrow is not an eqilibrium - it fully dissociates and the second only partially so some of the HSO4- will donate protons. Only in a very acidic environment would HSO4- act as a base.

HCl, HBr, and HI are all strong acids, whereas HF is a weak acid.

HCO3- (known as bicarbonate) is the conjugate base of H2CO3, a weak acid, and the conjugate acid of the carbonate ion. HCO3- acts as a base when mixed with a compound that is more acidic than itself (larger Ka) and as an acid when mixed with a compound that is more basic than itself (smaller Ka).

If one of the ions is OH-, the solution is basic. An example of a strong base is sodium hydroxide (NaOH). There are other ions that make acidic and basic solutions, but we won't be talking about them here.

All acids beginning with the prefix „hydro“ are otherwise known as binary acids. HCl, which contains the anion chloride, is called hydrochloric acid. HCN, which contains the anion cyanide, is called hydrocyanic acid. ... Since all these acids have the same cation, H+, we don't need to name the cation.

The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only). ... They simply do not ionize completely whereas a strong acid or base does.

Hydrogen chloride gas and hydrochloric acid have the same chemical formula: HCl. The difference between the two is that hydrogen chloride is a gas, and hydrochloric acid is an aqueous solution. ... The lower the pH, the stronger the acid. Hydrochloric acid is highly reactive with metals.

Hydrochloric acid, HCl(aq), is a strong acid. Sodium hydroxide, NaOH(aq), is a strong base. NaCl(aq) is a neutral solution.

(b) Potassium perchlorate, KClO4, is a neutral salt. Neither K+ nor ClO4- has any tendency to donate or accept a proton in dilute aqueous solutions. The reaction between a strong base KOH and the strong acid HClO4 produces KClO4. (c) Potassium hydrogen sulfate (also called potassium bisulfate) is an acidic salt.
