Which of the following acid is strongest acid?
HF is the strongest acid among the following.
Acidity increases with increase in the electronegativity.
Fluorine has greater electronegativity than oxygen.
So, HF is a strong acid..
Which is weakest acid?
Examples of Weak AcidsFormic acid (chemical formula: HCOOH)Acetic acid (chemical formula: CH3COOH)Benzoic acid (chemical formula: C6H5COOH)Oxalic acid (chemical formula: C2H2O4)Hydrofluoric acid (chemical formula: HF)Nitrous acid (chemical formula: HNO2)Sulfurous acid (chemical formula: H2SO3)Phosphoric acid (chemical formula: H3PO4)
Why nitric acid is strong acid?
Nitric acid is a stronger acid than nitrous acid because its conjugate base is more stable. The NO3- ion has excess negative charge spread out over 3 oxygen atoms while the excess negative charge in NO2- is spread out over on 2 oxygen atoms.
Does hydrochloric acid lose strength?
some acids like HCl, for example, are a gas dissolved in water. The HCl will be present in the vapor space over the liquid acid. If the container is open, HCl gas will escape and the acid solution will therefore become diluted over time. Some organic acids would also be affected in this way.
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.
What is the PH of stomach acid?
The normal volume of the stomach fluid is 20 to 100 mL and the pH is acidic (1.5 to 3.5). These numbers are converted to actual acid production in units of milliequivalents per hour (mEq/hr) in some cases.
Is nitric acid toxic?
Toxicity after inhalation exposure to nitric acid is similar in humans and animals. Nitric acid fumes may cause immediate irritation of the respiratory tract, pain, and dyspnea, followed by a period of recovery that may last several weeks.
What happens when we drink acid?
Symptoms from swallowing hydrochloric acid may include: Mouth and throat burn, causing severe pain. Drooling. Breathing difficulty due to swelling of throat.
How strong is magic acid?
This week’s molecules combine to make “magic”. The first, fluorosulfuric acid (HSO3F; also called fluorosulfonic acid) is an extremely strong Brønsted acid that has been known since the late 19th century. It is ≈1000 times stronger than pure sulfuric acid, which puts it in the class of superacids.
What acid is stronger than nitric acid?
Sulfuric acidOne way to look at it is based on the following: Sulfuric acid is a stronger acid than nitric acid. Consider the lewis dot structures shown below. All of the hydrogen atoms are attached to oxygen atoms in these acids.
Which is the strongest acid?
carborane acidThe world’s strongest acid, at least a million times more potent than concentrated sulphuric acid, has been made in a lab in California. Perhaps confusingly, it is also one of the least corrosive. The compound, called a carborane acid, is the first ‘superacid’ that can be stored in a bottle, say its creators.
What’s the worst acid?
Hydrofluoric acid (HF)Hydrofluoric acid (HF) is a solution of hydrogen fluoride in water. Its chemical formula is HF. It is a very dangerous acid, being very corrosive and extremely toxic. It can dissolve glass to make hexafluorosilicic 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)
What is the most corrosive liquid?
Sodium hydroxide (also known as lye) is one of the most corrosive of all bases. It generates significant heat when diluted and has an extremely high alkalinity (concentration of alkali elements in the solution).
Does nitric acid react with hydrochloric acid?
Upon mixing of concentrated hydrochloric acid and concentrated nitric acid, chemical reactions occur. These reactions result in the volatile products nitrosyl chloride and chlorine gas: HNO3 (aq) + 3 HCl (aq) → NOCl (g) + Cl2 (g) + 2 H2O.
Is hydrochloric acid stronger than sulfuric acid?
The pKa value of hydrochloric acid (HCl H C l ) is -6.3. The pKa of sulphuric acid (H2SO4 H 2 S O 4 ) is -3. … This means that HCl will dissociate into protons and chloride ions more easily than sulphuric acid will dissociate. Consequently, HCl is the stronger acid.
Why use hydrochloric instead of nitric acid?
Nitric acid is used because all nitrate salts are soluble in water. If we use H2SO4 or HCl they will produce sulphate or chloride salts. Some metal sulphates and chlorides are not very soluble in water.
What is the strongest base in the world?
ortho-diethynylbenzene dianionThe title of strongest base in the world belongs to ortho-diethynylbenzene dianion. This superbase has the strongest proton affinity ever calculated (1843 kJ mol−1), beating out a long-standing contender known as lithium monoxide anion.
What is the most dangerous liquid?
1. Botulinum toxin. Scientists differ about the relative toxicities of substances, but they seem to agree that botulinum toxin, produced by anaerobic bacteria, is the most toxic substance known. Its LD50 is tiny – at most 1 nanogram per kilogram can kill a human.
What is the strongest alkali in the world?
Sodium Hydroxide(caustic soda) is the most basic compound and so has a PH of 14 as indicated on the arbitiary scale making its medium most alkalinic. Aqueous caustic soda turns red litmus paper blue with a degree in less than a second compared to other bases of same or different category .
What happens when nitric acid is added to water?
Nitric acid, HNO3, was known to the alchemists of the 8th century as “aqua… … The resulting acid-in-water solution (about 50–70 percent by weight acid) can be dehydrated by distillation with sulfuric acid. Nitric acid decomposes into water, nitrogen dioxide, and oxygen, forming a brownish yellow solution.
