What is Hydrochloric acid (hcl) dissociates completely into an h plus ion and a cl- ion when dissolved in water?

First of all the formula for hydrochloric acid is 'HCl'. NOT 'hcl'. For single letter symbols it is ALWAYS a CAPITAL letter ; hence hydrogen is 'H'. For two letter symbols , the first letter is a CAPITAL letter and the second letter is lower case., hence chlorine is 'Cl;. This is the recognised international standard.
To answer you question .
HCl is hydrogen chloride , which is a gas. However, it readily dissolves in water to form hydrochloric acid. As it dissolves it form the ions 'H^(+)' and 'Cl^(-)'. It is the 'H^(+)' ion that is the acid component and pH is measured against it.
HCl does NOT remain undissociated in water.
Yes I agree it can be confusing. The formula HCl is the same for the gas and the acid.

How is a weak acid different from a strong acid?
A strong acid completely dissociates into ions when dissolved in water while a weak acid only partially dissociates.

Is hydrochloric an acid or base?
Hydrochloric Acid or HCl is a strong acid. This is because it dissociates completely in water (the very definition of a strong acid/base) into H+ and Cl-. Since H+ are free in the water it causes the water to become more acidic and therefore an acid. The dissociation coupled with the free H+ after dissociation give it the classification of a strong acid.
Is Chlorine strong or weak?
Chlorine is a strong electrolyte - it always completely dissociates in water. HCl (hydrochloric acid) is a strong acid as well, for the same reason.
How strong is a acid different from a weak acid?
A strong acid completely dissociates into ions when dissolved in water while a weak acid only partially dissociates.

Is a chemical which partially dissociates into ions when it dissolves in a water a strong electrolyte?
No, strong electrolytes completely dissociate into ions when dissolved in water.

Is aluminum nitrate and electrolyte when mixed with distilled water?
Aluminum nitrate, when dissolved in water, completely dissociates from Al(NO3)3 to Al+3 and NO3-1 ions. It is a strong electrolyte.

What is a strong electrolyte?
When substances are dissolved in water they create ions. A strong electrolyte is when separate ions are formed in water. Note that pure water does not conduct electric currents. But ionic water does. A strong electrolyte is merely a collection of ions that interact with each other.
Is Chlorine strong or weak?
Chlorine is a strong electrolyte - it always completely dissociates in water. HCl (hydrochloric acid) is a strong acid as well, for the same reason.
What does a strong acid do for a chemist?
It dissociates (or ionizes) nearly completely with water.
What is the difference between a weak acid and a strong acid such as hydrochloric acid?
A strong acid dissociates more or less completely in water; a weak acid exists partially in dissociated form and partly in molecular form.
Why is sodium hydroxide a strong base?
because it completely dissociates in water
