What is the world’s 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..
Is pH above 14 possible?
When a base, or alkaline, is dissolved in water, the pH will be greater than 7. A solution of a strong alkaline, such as sodium hydroxide, at concentration 1 mol dm−3, has a pH of 14. Mostly – measured pH values will lie in the range 0 to 14, though negative pH values and values above 14 are entirely possible.
What is the pH of a lemon?
Lemon juice in its natural state is acidic with a pH of about 2, but once metabolized it actually becomes alkaline with a pH well above 7. So, outside the body, anyone can see that lemon juice is very acidic.
What has a pH of 7?
Pure water is neutral. It is neither acidic nor basic, and has a pH of 7.0. Anything below 7.0 (ranging from 0.0 to 6.9) is acidic, and anything above 7.0 (from 7.1 to 14.0) is alkaline.
Which is more dangerous acid or base?
Explanation: Acids and bases have various strengths, all depending on their pH . An extremely strong base would be more dangerous than a weak acid, and vice versa.
Is pH of 22 possible?
The pH scale describes how many hydrogen ions (protons) are present in a solution. The pH scale typically stretches from zero to 14, passing through a neutral pH7 (freshly distilled water). … But the scale does not have fixed limits, so it is indeed possible to have a pH above 14 or below zero.
Which pH is the weakest acid?
A substance with a pH of 5 or 6 would be a weak acid. A substance with a pH of 13 or 15 would be a strong base. A substance with a pH of 8 or 9 would be a weak base.
What solution has a pH of 12?
Label each solution as acidic, basic, or neutral based only on the stated pH. With a pH greater than 7, milk of magnesia is basic. (Milk of magnesia is largely Mg(OH) 2.)

What pH is dangerous?
The danger of more acidic water – when the pH is less than 6.5 – is that it can leach metals from the well and from the pipes that bring you water. These metals include lead, manganese, copper and iron, and they can be toxic in large amounts. So acidic water obviously poses a health risk.
Is a pH of 14 dangerous?
In terms of pH hydrofluoric acid is considered a weak acid – it does not fully ionize in water – but it is extremely dangerous because of how corrosive it is. … Liquid Drain Cleaner: pH = 14.
Why pH is not more than 14?
pH = 14 corresponds to an aqueous solution of a strong base of molarity 1. By the same definition, pH = 0 corresponds to an aqueous solution of a strong acid or molarity 1. Higher concentrations result in pH > 14 for strong bases and pH < 0 for strong acids. ... So, that's why, the pH is not more than 14.
Is pH 12 a strong base?
Strong Bases Like strong acids, a strong base dissociates nearly completely in water; however, it releases hydroxide (OH-) ions rather than H+. Strong bases have very high pH values, usually about 12 to 14.
What is the strongest base in the world?
The methyl anion H3C– was the strongest known base for 30 years, until Tian and colleagues made the lithium monoxide anion in 2008, which has held the record since. Now, scientists in Australia have knocked LiO– down to second place, making a gas-phase dianion with the highest basicity ever found.
Why is pH used instead of H+?
Originally Answered: Why is the pH scale used only for determining the concentration of H+ ions? Because that is what pH is defined as. The pH is the negative logarithm of the hydrogen ion concentration. You can also have pOH.
What has the highest pH?
By definition, the strongest base in water is hydroxide (OH-). Any compound that dissociates completely and is a hydroxide can produce the highest pH (i.e., 14).
