Sodium Hydroxide pH is 13.0
Weakest base is that which is strongest acid the latest research proves that strongest acid is a mixture HF.SbF5 Antimonic acid.
Acetic acid is a weak acid. The other three are strong.
The highest pH an acid can have is just below 7.
ka= 1.62 x 10^-12
The Ka value closest to 1 x 10^-7 represents the weakest acid, as this value corresponds to a neutral solution and indicates a weaker dissociation of the acid.
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.
No. Nitric acid is a very strong acid. However, it's not the strongest acid in the world, though. Sulfuric acid is stronger than nitric acid, but the carbonic superacids are also stronger than sulfuric acid.
=Fluoroantimonic acid is by far the strongest acid being approximately 20,000,000,000,000,000,000 times as strong as 100% sulphuric acid and with a pH of -25.==The weakest acid is less distinguished. However, carbonic acid is an example of a weak acid.=
2,4 is a lower pH than 10,1.
The pH of the weakest acid would likely be close to neutral, around 6-7, as weak acids only partially ionize in water resulting in a small concentration of H+ ions and a slightly acidic pH.
Phosphoric acid (H3PO4) undergoes three dissociation reactions to form H2PO4-, HPO4^2-, and PO4^3-. Among these, the first dissociation reaction to form H2PO4- is the weakest because it involves losing only one proton.
The weakest acid known is going to be placed right before neutral (7) on the pH scale. This question is difficult to answer, because there are so many acids in nature, including organic acids. Most acids are weak acids. If you had a list to choose from, you could have a better answer.
