A larger Ka indicates that the acid will more readily react as the molecular bonds are relatively weak. The Ka is known as the dissociation constant.
Sulfuric acid is more stronger than Nitric acid, but Nitric acid is more reactive than Sulfuric acid.
The constants Ka and Kb relate to the relative strengths of series of acids or bases by being proportional. The higher the Ka or Kb value, the stronger the acid or base.
To make an acid stronger, you can increase its concentration or decrease its dissociation constant (Ka). Increasing the concentration of an acid will increase the number of acid molecules available to donate protons, making it stronger. Decreasing the dissociation constant means that less of the acid will dissociate into ions, resulting in more undissociated acid molecules available to donate protons. Conversely, to make an acid weaker, you can decrease its concentration or increase its dissociation constant.
The Ka values that represent the weakest acid are low numbers. For instance, hydronium ion (H3O+) is a weak acid with a Ka of 1.0. On the other hand, hydrogen sulfide (H2S) is a strong acid with a Ka of 9.1 x 10-8.
According to CRC reference data, the pKa of sulfamic acid is 1.05, giving a Ka of 11.2. This is a strong acid.
No. An acid with a large Ka is stronger. A lower pKa indicates a stronger acid.
Sulfuric acid is more stronger than Nitric acid, but Nitric acid is more reactive than Sulfuric acid.
if you mean why is it when [H+] = [A-] related to the Ka of a weak acid. look at the definition of Ka. Ka = [H+][A-]/[HA]
As with any acid, that depends entirely on its concentration. The greater the concentration (until saturation) the lower the pH. Lactic acid is a "middle of the road" weak acid; all in equal concentrations, lactic acid is stronger than citric, weaker than acetic, and about the same as formic.
The constants Ka and Kb relate to the relative strengths of series of acids or bases by being proportional. The higher the Ka or Kb value, the stronger the acid or base.
It refers to the acidity of the fatty acid (which make up the oils). Every fatty acid is composed of a non-polar long chain of hydrocarbons (carbon and hydrogen) and a polar head made up of Carboxylic ACID. Every acid has something called pKa which determines the acidity of that acid.The bigger the pKa (e.g. 25), the weaker the acid.The smaller ther pKa (e.g. 2), the stronger the acid.

pKa = -log Ka and thus Ka = 10^-pKaKa = antilog pKaKa = 7.76x10^-6
According to CRC reference data, the pKa of sulfamic acid is 1.05, giving a Ka of 11.2. This is a strong acid.
Hydrochoric acid is more acidic than Picric acid.Added: Ka(Picric acid) = 0.38, Ka(HCl) >>1
NaOH does not have a Ka because it is not an acid. Ka is the concentration of the acid, therefore non valid. It can have a Kb though. Hope this helps
