The pH scale
Which name identifies the acid HBr?
This is definitely an acid. It is the chemical formula for hydrobromic acid, which is actually one of the six strongest acids. It will dissociate immediately in water to form a high concentration of the H+ ion, and the concentration of that ion is what determines the pH of the substance. High ion concentration, low pH, strong acid.
What factor determines the strength of an acid or a base?
The strength of an acid or base depends on its concentration. More the concentration of Hydrogen ions [H+] more acidic it is and more the concentration of Hydroxide ions [OH-] more basic it is.
Is perchloric acid a weak acid?
Actually perchloric acid (HClO4) is a much stronger acid than chlorous acid (HClO2). The strength of an acid is determined by the ability of a hydrogen ion (H+) to break away. Perchloric acid has more oxygen, which is electron withdrawing, in a molecule, making it easier for the H+ ion to break away.
The strength of an acid based on concentration of what ions?
Hydrogen ion (H+) [technically it is hydronium ion (H3O+)] that determines the strength of an acid. A mole of hydrochloric acid (HCl) produces 1 mole of H+ ions, then that is a strong acid. Weak acids give smaller amounts of H+ for a mole of substance.

The strength of an acid is based on the concentration of What is ions?
The strength of an acid is based on the concentration of What ions? HCl + H2O = H3O^+1 + Cl^-1 H3O^+1 is the hydronium ion that all acids produce in water. The more hydronium ions per liter of acid, the stronger the acid!!
What are -A ions?
The A- ion is the generic term for the conjugate base of an acid. The charge is balanced by an H+ ion. The identity and formula of this ion depends on the acid, for example, if the acid is acetic CH3CO2H acid, A- is the acetate ion or CH3CO2- If it is sulfuric acid (H2SO4) A- is the bisulfate ion HSO4-
What determines the safeness of a acid?
The pH value determines the safeness of acid and how effective it is.
The strengh of an acid is based on the concentration of ions?
The hydronium ion (H30+) concentration is what determines the strength of an acid. When I took Chemistry, it was referred to as just H+ ion, but it seems that they've determined that lone protons do not just float around in a solution by themselves (a hydrogen atom stripped of it's electron would be just a proton). So the lone proton makes a bond with an H2O molecule and becomes H30+. The convention to use the H+ designation remains.
Is a strong acid concentrated?
No. The strength and concentration of and acid are completely unrelated. A strong acid may be concentrated or dilute; the same is true of a weak acid. The strength of an acid is a specific chemical property of that substance involving how easily a hydrogen ion (H+) will break away from the molecule while concentration is the amount of the substance dissolved in a given volume of water.
What happens when you put acid into a solution?
Putting an acid in water will result in dissociation. For example, when hydrochloric acid is put in water, HCl becomes H+ (hydronium ions) and Cl- (chloride ions). The degree to which the acid dissociates determines it's strength.
