A strong base will, in water, fullyhydrolyse to give (react into) hydroxide (OH-) ions.
A weak acid will, in water, partially hydrolyse to give (react into) hydronium(H3O+, or H+) ions.
The strong/weak difference is in bold, the base/acid difference is itallicalized.
A strong acids dissociates completely in water to produce hydronium (H3O+) ions
A strong base dissociates completely in water to produce hydroxide (OH-) ions
A strong acid will dissolve just about anything that is put in it. A weak base will do just about nothing.
how can concentration can be achieved easily while studying .
No a strong base has a very low concentration of H+ atoms and a pH of approx. 13. A weak acid has a concentration of H+ atoms slightly high than water with a pH of 6 ish.
A strong acid or base is always a strong electrolyte.
the pH range of a strong acid
An acid produces H+ ions when they are put in water. A base produces OH- ions when they are put in water.
Strong Acid + Strong Base ---> Neutral Salt + Water
Usually a strong acid will produce a lower pH, but not always. pH is not a measure of the strength of an acid (or base) but the acidity of a solution, which is dependent on both the strength of the acid or base and its concentration in the solution.
If acid is strong then its conjugate base must be weak, if conjugate base is strong it again accept the H+ ions so acid can neither be strong, similarly if base is strong its conjugate acid must be weak.

Strong acids/bases will dissociate to almost 100% in water and their conjugate base/acid will be weak. Weak acid/base will not dissociate well in water and their conjugate base/acid will be strong.

A salt is formed when a strong acid reacts with a strong base.
Depends On their PH Level. A PH Scale will tell you the strength of an acid- OR base. The strength depends on how much it canw wear materials and how diluted it is.
A salt is formed when a strong acid reacts with a strong base.
It is a strong acid
alkaline obviously! strong acid + strong base= neutral strong acid + weak base= acidic weak acid + strong base= alkaline
