why are hcl and naoh electrolytes in water?

Each mole of sodium hydroxide that dissolves will produce one mole of sodium ions and one mole of hydroxide ions. ... HCl is a strong electrolyte and when it dissolves in water it separates almost completely into positively - charged hydrogen ions and negatively - charged chloride ions.

In part because of its high polarity, HCl is very soluble in water (and in other polar solvents). Upon contact, H2O and HCl combine to form hydronium cations H3O+ and chloride anions Cl− through a reversible chemical reaction: HCl + H2O → H3O+ + Cl.

HCl is a strong electrolyte and when it dissolves in water it separates almost completely into positively - charged hydrogen ions and negatively - charged chloride ions. This aqueous solution is usually called hydrochloric acid.

When you dissolve it in water, HCl is broken up into the ions H+ and Cl-. It is these ions that are stabilized in water, and usually, they can be quite far apart from one another. So the reason that HCl dissolves in water despite being covalent, is that it is willing to break up into ions.

Answer Expert Verified Electrolytes are substances that conduct electricity when in an aqueous solution. These include the ionic compounds and the strong acids and bases. ... Thus, it is covalent so you would expect this to be a nonelectrolyte or a weak electrolyte.

Sodium hydroxide, NaOH(s), is used in drain cleaners. It is an ionic solid made up of sodium ions, Na+, and hydroxide ions, OH-. Therefore there will be lots of ions in solution to conduct electricity. Therefore an aqueous solution of sodium hydroxide is a strong electrolyte.

Reactions of Acids and Bases A salt is a neutral ionic compound. Let's see how a neutralization reaction produces both water and a salt, using as an example the reaction between solutions of hydrochloric acid and sodium hydroxide. The overall equation for this reaction is: NaOH + HCl → H2O and NaCl.

Sodium hydroxide (NaOH) is strong base because it fully dissociates in water to produce hydroxide ions. ... While weak bases produce fewer hydroxide ions, making the solution less basic.

In an aqueous solution a strong electrolyte is considered to be completely ionized, or dissociated, in water, meaning it is soluble. Strong acids and bases are usually strong electrolytes.

Ionic compounds dissolve in water because the water molecules hydrate the ions.

ConductivityEdit Acids and bases in aqueous solutions will conduct electricity because they contain dissolved ions. Therefore, acids and bases are electrolytes. ... Weak acids and bases will be weak electrolytes.

Electrolytes are salts or molecules that ionize completely in solution. As a result, electrolyte solutions readily conduct electricity. Nonelectrolytes do not dissociate into ions in solution; nonelectrolyte solutions do not, therefore, conduct electricity.

NaOH therefore dissociates to give Na+ and OH- ions when it dissolves in water. ... These compounds, such as Al2O3 and Al(OH)3, are called amphoteric (literally, "either or both") because they can act as either acids or bases. Al(OH)3, for example, acts as an acid when it reacts with a base.

Covalent Electrolytes In some cases, we find that solutions prepared from covalent compounds conduct electricity because the solute molecules react chemically with the solvent to produce ions. ... This reaction is essentially 100% complete for HCl (i.e., it is a strong acid and, consequently, a strong electrolyte).

Re: NaOH + NaCl Nothing happens chemically, but the dissolved NaOH will reduce the amount of NaCl that can dissolve in solution (because NaOH is more soluble than NaCl, and there's a common ion effect with the sodium ion).

NH4OH, being a weak base, ionizes to a less extent while NH4Cl being a strong electrolyte ionizes almost completely. When a small amount of strong acid like HCl is added, the H+ ions combines with OH- to form un-dissociated water molecules. However, to maintain Ka constant, NH4OH dissociates more thus removing H+ ions.
