Why is HCl a strong electrolyte?
Determine the strength of hydrochloric acid as an electrolyte: Hydrochloric acid, HCl(aq), dissociates completely so there are many ions in solution to conduct electricity therefore hydrochloric acid is a strong electrolyte.
Why is HCl a weak electrolyte?
However, when HCl is dissolved in water, it conducts a current well because the HCl molecule ionizes into hydrogen and chloride ions. When HCl is dissolved into water, it is called hydrochloric acid. A weak electrolyte is a solution in which only a small fraction of the dissolved solute exists as ions.
Which of the is not weak electrolyte?
D is the only one listed here that is not a weak electrolyte. It is actually a strong electrolyte because it is a strong acid. It doesn’t like to stay in equilibrium. It likes to associate completely.
Why HCl is a strong acid and CH3COOH is a weak acid?
HCl is a strong acid because it dissociates almost completely. By contrast, a weak acid like acetic acid (CH3COOH) does not dissociate well in water – many H+ ions remain bound-up within the molecule.
Why is HCl a strong electrolyte while CH3COOH is a weak electrolyte?
Originally Answered: Why is HCl a strong electrolyte while CH3COOH is a weak electrolyte?My question is not about the definitions but about why the particular compounds behave like that. Hydrochloric acid is a strong electrolyte because it dissociates completely into hydrogen and chloride ions.
What is the strongest electrolyte that can ionize with water?
Calcium nitrite is the only strong electrolyte listed, and will react with water to give THREE equiv of ions… On the other hand, you got acetic acid, hydrocyanic acid, and ammonia …. for none of which will complete ionization occur. Ammonium hydroxide, N H 4 O H, is better represented as N H 3 • H 2 O ( a q), and this is a WEAK Bronsted base…
Is FeCl2 a strong or weak electrolyte?
Since it’s a soluble ionic salt, we can say that FeCl2 is a strong electrolyte. • H2CO3: Recall that H2CO3 is one of the weak acids. Since it’s a weak acid, we can say that H2CO3 is a weak electrolyte.
Why is HClO4 and HNO3 acidic?
HNO3 is white fuming nitric acid (NOT an acid, but a very strong oxidizing agent). HClO4 is perchloric acid. Again the anhydrous substance, a colourless oily liquid, is not an acid but a strong (and unstable) oxidizer. The reason none of them are acidic is that there are no water molecules to accept a proton and form the hydronium ion, H3O+.
