Quick Answer: Which Is The Strongest Acid?

What are the 7 strong acids?

Hydrochloric Acid (HCl) Hydrochloric acid, also known as muriatic acid, is a chemical compound with the formula HCl.

Hydrobromic Acid (HBr) …

Hydroiodic Acid (HI) …

Sulfuric Acid (H2SO4) …

Nitric Acid (HNO3) …

Perchloric Acid (HClO4) …

Chloric Acid (HClO3).

Is HCl the strongest acid?

HCl, HBr, and HI are all strong acids, whereas HF is a weak acid. The acid strength increases as the experimental pKa values decrease in the following order: HF (pKa = 3.1) < HCl (pKa = -6.0) < HBr (pKa = -9.0) < HI (pKa = -9.5).

What is the weakest acid?

hydrofluoric acidThe only weak acid formed by the reaction between hydrogen and a halogen is hydrofluoric acid (HF).

Why isn’t Hf a strong acid?

However, it is a weak acid and not a strong acid because it does not completely dissociate in water (which is the definition of a strong acid) or at least because the ions it forms upon dissociation are too strongly bound to each other for it to act as a strong acid.

Which is the strongest acid and why?

The World’s Strongest Acid The record-holder used to be fluorosulfuric acid (HFSO3), but the carborane superacids are hundreds of times stronger than fluorosulfuric acid and over a million times stronger than concentrated sulfuric acid.

Which is the most dangerous acid?

Incidents involving hydrogen fluoride, or hydrofluoric acid, are not common, but the consequences of exposure to this compound by any means can be devastating. This little-known acid has unique properties that make it extremely dangerous to emergency personnel and others.

Which is king of acid?

Sulfuric acidSulfuric acid is commonly supplied at concentrations of 78, 93, or 98 percent. Sulfuric acid is sometimes referred to as the “king of chemicals” because it is produced… Due to its affinity for water, pure anhydrous sulfuric acid does not exist in nature.

Is HCl stronger than sulfuric acid?

The lower the pKa value for an acid, the higher the Ka value of the acid. … Therefore, As the pKa value for HCl is smaller, its Ka value will be larger. This means that HCl will dissociate into protons and chloride ions more easily than sulphuric acid will dissociate. Consequently, HCl is the stronger acid.

Is HCl or HI stronger?

HI has longer bond than HCl, making its bond weaker. Therefore it is easier for HI to lose H+, making it a stronger acid.
