is cucl2 an acid or base?

In solution, it is acidic. Copper chloride is the result of the neutralization reaction between hydrochloric acid and copper hydroxide. With that in mind, it is the salt of a reaction between a strong acid and a weak base, making an aqueous solution of copper chloride slightly acidic.

LiCl is an ionic compound because Li is a metal (all elements in the first 2 rows are metals) and chlorine is a non-metal.

If one of those ions is H+, the solution is acidic. The strong acid hydrogen chloride (HCl) is one example. If one of the ions is OH-, the solution is basic. An example of a strong base is sodium hydroxide (NaOH).

Nickel(II) chloride solutions are acidic, with a pH of around 4 due to the hydrolysis of the Ni2+ ion.

Although CuCl is insoluble in water, it dissolves in aqueous solutions containing suitable donor molecules. It forms complexes with halide ions, for example forming H3O+ CuCl2− in concentrated hydrochloric acid.

Since Ca(ClO4)2 is a strong acid-strong base salt, the pH of the1.

Copper (II) sulphate pentahydrate, CuSO4⋅5H2O, indicates copper (II) sulphate in crystalline form (for ease you can say copper (II) sulphate whose crystals contain water). Copper (II) sulphate, CuSO4, indicates anhydrous copper (II) sulphate (copper sulphate which has lost its water molecules).

OH, or hydroxide, group. Metal hydroxides, such as LiOH, NaOH, KOH, and Ca(OH)2, are bases. Nonmetal hydroxides, such as hypochlorous acid (HOCl), are acids.

CuSO4 is polar in nature as CuSO4 forms ionic bond so it is ionic compound and it is one of property of ionic compound that they are polar as ionic compounds had ions of unlike charges or opposite charges which is held together by strong electrostatic force of attraction.

a) NaBr - neutral Na+ has no acidic or basic properties and since Br- is the conjugate base of a strong acid it is a nonbase. is the conjugate base of a weak acid it is a weak base. weak acid and since Cl- is the conjugate base of a strong acid it is a nonbase. the conjugate base of a weak acid it is a weak base.

CuCl has more covalent character than NaCl because Cu+ has more polarizing power than Na+. Higher is the polarizing power of the cation, higher is the covalent character.

Since HCl is a strong acid and ionizes completely in water, Cl- is a very weak base. The conjugate acid of NH2- is NH3, called ammonia. Ammonia is actually itself a weak base, so its conjugate base NH2- is an incredibly strong base so it can get an extra proton to regenerate NH3 which is much more stable.

All acids under the Lowry-Bronsted definition, yes. Under the Lewis definition, metal ions can be acids, so obviously for them the answer is no. The most common bases are metal hydroxides, which are mostly ionic, like NaOH. Some weak bases (like ammonia) are covalent.

A salt formed from reaction of a weak base and a strong acid should give an acidic solution. For example, NH4Cl is formed from the reaction of NH3, a weak base, and HCl, a strong acid. The chloride ion will not hydrolyze. ... A salt formed from reaction of a strong base and a weak acid should give a basic solution.

Strong acids have a weak conjugate base. Thus, the Cl- ion must be a weak base. Strong bases have a weak conjugate acid.

FeCl3 is an acid salt because Fe(OH)3 is weak base and HCl is a strong acid. pH is less than 7.
966425
The ions from KCl derive from a strong acid (HCl) and a strong base (KOH). Therefore, neither ion will affect the acidity of the solution, so KCl is a neutral salt.
