Is KCl acidic or basic??

[Nicolas Zarco 2K]

KCl is neutral as Cl is a weak base and K is a weak acid.

Hi!
KCl is neutral.

K comes from the strong base KOH so it manifests into a weak conjugate acid.

Cl comes from the strong acid HCl, so it manifests into a weak conjugate base.

Because neither has strong acidic or basic properties, KCl is neutral.

Pretty sure KCl is neutral, would look into it further

[Kayley Steele 3D]

KCL is neutral because KOH is a strong base and Cl is a strong acid. A strong base and a strong acid will always result in neutral molecule.

K+ is a cation that is the conjugate of KOH, a strong base. Cl- is an anion that is the conjugate of HCl, a strong acid. Therefore, this salt is considered neutral.

[Erika Li 1E]

KCl is a neutral salt because it is the result of the neutralization of a strong acid (HCl) and a strong base (KOH). This means that both the K+ cation and Cl- anion won't affect the acidity of the solution, and KCl is a neutral salt.

[Veronica Larson- 1I]

KCl is a neutral salt. The way that I like to think about these problems is to determine what base and acid the salt forms from (like in a neutralization reaction), and compare their relative strengths. In this case, KCl is from a reaction of KOH (a strong base) and HCl (a strong acid), so the salt would be neutral.

Hi,

To determine the characteristics of a given salt (i.e., if it is acidic, basic, or neutral),

1. Determine the cation and anion of the salt.
In an aqueous solution, KCl dissociates/ionizes to form K⁺ and Cl^-.

1. Derive the parent acid and parent base of the salt. (Note: A salt is always the product of an acid-base neutralization reaction.)
The cation of the salt is always from the base of the neutralization reaction, and the anion of the salt is always from the acid of the neutralization reaction.
For KCl, the potassium cation (K⁺) is derived from the base KOH and the chloride anion (Cl^-) is derived from the acid HCl.

2. Determine whether the parent acid and parent base are strong or weak.
KOH is a strong base (group 1 metal hydroxide) and HCl is a strong acid (one of the 7 strong acids).

3. Ions of strong parent acids/bases are spectator ions that do not affect the pH of the solution. Spectator ions are ions that do not take part in the chemical reaction and are found in the solution both before and after the reaction.

4. Ions of weak parent acids/bases affect the pH of the solution. The cation (i.e., conjugate acid) of a weak base acts like an acid and lowers the pH. The anion (i.e., conjugate base) of a weak acid acts like a base and increases the pH.

Because the potassium cation (K⁺) and the chloride anion (Cl^-) of the KCl salt are derived from a strong parent base/acid respectively, they are both spectator ions and the pH is ultimately not affected/remains as 7. Therefore, KCl is a neutral salt.

Hope this helps!

Neutral since neither K+ or Cl- has a charge BUT to be *technical* Cl- is an extremely extremely extremely weak base (weaker than H2O) so it is totaaaaally negligible for the purposes of the class

[Michael 1G]

Since the potassium comes from KOH (strong base) and chlorine comes from HCL (strong acid) the acidity of the aqueous solution is unaffected, making KCl a neutral salt.
