Why do you use a double arrow to show the dissociation of a weak acid or weak base in aqueous solution?
Double arrow means reversible reaction while single arrow represents complete reaction.For strong acid such as HCl,they undergo ionization to form H+ and Cl-.For weak acid such as H2CO3,it undergoes reversible reaction. H2CO3->H+ + HCO3- HCO3- <->H+ + CO3 2-
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.
What is an acid dissociation constant?
An acid dissociation constant is the equilibrium constant for the disassociation of an acid, ultimately a measure of the acid's strength.
Is sodium thiosulphate an acid or a base?
Sodium thiosulphate is a somewhat strong acid with pKas of 0.6 and 1.7 for the first and second dissociation respectively.
Is dilute hydrocloric acid a strong acid?
Whether or not an acid is strong doesn't depend on concentration. Most definitions for acid strength depend on the acid dissociation constant (pKa). Strong acids are generally defined as those with a pKa less than -1.74. Since HCl meets this definition, it is a strong acid, regardless of concentration.
What will a strong acid have more of when compared to a weak acid?
The strong acid has a higher dissociation constant.
The acid formed when hydrogen iodide dissociates in an aqueous solution would be named?
Hydroiodic Acid. It is a strong acid (100% dissociation).
Is sulfuric acid is known as as astrong acid?
According to the definition, a strong acid should dissociate completely. The second dissociation constant in sulfuric acid is nearly 95% and therefore is considered to be a strong acid.
What makes an acid stronger than the other?
The difference is between dissociation constants. A high value has the meaning of strong acid.
What properties cause an acid or a base to be strong or weak?
This depends on the level of dissociation of acids or bases.

Is HI a weak electrolytes?
No, HI is very strong. In solution it will undergo complete dissociation, so it will only consist of H+ ions and I- ions. This makes it very electrolytic, and therefore a strong acid.
The acid dissociation constant for an acid dissolved in water is equal to?
The strength of an acid or the measure of its tendency to release proton ions (H+) can be indicated from its dissociation constant which is called Ka. The acid dissociation constant, pKa , is the negative logarithm of dissociation constant (Ka).
