WHAT determines if an acid will be strong or weak?

Answer 1

The ability of dissociation and the concentration is what causes an acid to be strong or weak. If it is strong, it will dissociate in water and have a pH lower than 7. A weak acid will partially dissociate in water, and it will have a pH of 7 or greater.

Answer 2

In water only 7 acids are strong: (from strongest to strong)

HClO4, HI, HBr, HCl, H2SO4, HNO3, HClO3 are all 'stronger' then H3O+ (Ka(H3O+) = 1)

All the rest of them are weak acids , Kacid <<1

Answer 3

Depending on what is meant by strength. In chemistry a acid is classified as "strong" if complete dissociation of all H+ occurs. HCl is a strong acid for example. But if you are regarding it in terms of the ability to dissolve it can still be regarded a weak acid in terms of chemistry. e.g hydrofluoric acid can dissolve glass, but since full dissociation does not occur it is not a strong acid.!

Answer 4

pH value determines whether an acid will be strong or weak. pH stands for the "power of Hydrogen ions." The number of ions determine how if a solution is a basic or acid.

pH scale starts from 0-14 where 7 is the neutral. The number of hydrogen ions and hydroxide ions are equal.

The number/concentration of Hydrogen ions (H+) in a solution is determines the solution's pH (whether or not it is basic or acidic).

Answer 5

The strength of an acid is determined by its ability to donate protons in a solution. Strong acids completely dissociate in water to form ions, while weak acids only partially dissociate. Factors such as bond strength and molecular structure influence whether an acid will be strong or weak.

Answer 6

The fact the ions completely or partially dissociate in an aqueous solution.

Answer 7

The strength of an acid depends on the concentration of hydronium ions.

Answer 8

An acid is strong if it gives up it's hydrogen ion easily, if not it is a weak acid.

Answer 9

This depends on the level of dissociation of acids or bases.
