Which is harder than diamond?
A diamond ring.
Scientists have calculated that wurtzite boron nitride and lonsdaleite (hexagonal diamond) both have greater indentation strengths than diamond.
(PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world.
Can fire damage a diamond?
Because diamonds are flammable, a house fire can destroy your jewels. Gold and platinum are not flammable, but will melt in a fire. The best way to store your diamonds and other jewelry is either in a fireproof safety deposit box at the bank or in a fireproof safe in your home.
What happens if you touch hydrofluoric acid?
Breathing hydrogen fluoride can damage lung tissue and cause swelling and fluid accumulation in the lungs (pulmonary edema). Skin contact with hydrogen fluoride may cause severe burns that develop after several hours and form skin ulcers.
Can acid destroy a diamond?
No, acids cannot dissolve diamonds, for the simple reason that a diamonds carbon atoms are too tightly packed together for the Hydrogen ions to be able to dissolve the substance.
What is the strongest alkaline?
(Higher tier) Strong alkalis completely ionise in water. They break up completely to produce a high concentration of hydroxide ions in the solution. Strong alkalis include: sodium hydroxide. potassium hydroxide.
What fruit is most acidic?
Fruits and fruit juices high in acidlemon juice (pH: 2.00–2.60)limes (pH: 2.00–2.80)blue plums (pH: 2.80–3.40)grapes (pH: 2.90–3.82)pomegranates (pH: 2.93–3.20)grapefruits (pH: 3.00–3.75)blueberries (pH: 3.12–3.33)pineapples (pH: 3.20–4.00)More items…
Which is king of acid?
Sulfuric acidSulfuric 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 acid a weak?
A weak acid is an acid chemical which does not dissociate (split into ions) completely in water solution. This means it does not give all its hydrogen ions into the water. Weak acids typically have a pH between 3 and 6. The relative strength of an acid can be expressed using Ka, the acid ionization constant.
Why Is aspirin a weak acid?
Aspirin is a weak acid and it tends to ionize (give up a H atom) in an aqueous medium at high pH. Drugs do not cross biological membranes when they are ionized. In a low pH environment like the stomach (pH =2), aspirin is predominantly unionized and crosses membranes into the blood vessels readily.
Can you eat hydrochloric acid?
Concentrated hydrochloric acid causes similar corrosive injury to the skin and, if ingested, can cause severe corrosive injury to the mouth, throat, esophagus, and stomach. There is no antidote for hydrogen chloride poisoning.
Which is the most dangerous acid in the world?
Hydrofluoric acid (HF): A weak acid, meaning it doesn’t fully dissociate into its ions in water, but it’s probably the most dangerous acid in this list because it’s the one you’re most likely to encounter.
What is the weakest acid?
hydrofluoric acidThe only weak acid formed by the reaction between hydrogen and a halogen is hydrofluoric acid (HF).
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).
Is hydrochloric acid a weak or strong acid?
Examples of strong acids are hydrochloric acid (HCl), perchloric acid (HClO4), nitric acid (HNO3) and sulfuric acid (H2SO4). A weak acid is only partially dissociated, with both the undissociated acid and its dissociation products being present, in solution, in equilibrium with each other.
What is the strongest type of 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.
How strong is Fluoroantimonic acid?
Fluoroantimonic acid is 2×1019 (20 quintillion) times stronger than 100% sulfuric acid. 1 Fluoroantimonic acid has a H0 (Hammett acidity function) value of -31.3. Dissolves glass and many other materials and protonates nearly all organic compounds (such as everything in your body).
Can Fluoroantimonic acid kill you?
You would most certainly die. The reasons are listed by Wikipedia here. Causes of death could include: Toxic HF fumes which destroy your alveoli, causing you to suffocate.
Which acid is most dangerous for skin?

What acids can kill you?
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 is the most basic substance on earth?
The Schlosser base (or Lochmann-Schlosser base), the combination of n-butyllithium and potassium tert-butoxide, is commonly cited as a superbase.
How do you tell if a diamond is real with a flashlight?
For the fog test, hold the diamond or ring between two fingers and breath on it with a puff of air. A light fog will form on the diamond because of the moisture and heat in your breath. If the fog dissipates right away, the diamond is real.
