Which solution has the lowest pH value?
Na is basic in nature.
HCO₃⁻ ions and CO₃²⁻ ions are from weak acid and Na is a strong base.
So the pH of NaHCO₃ and Na₂CO₃ are more than 7.
So NaCl has lowest pH..
What’s the worst acid?
Hydrofluoric acidHydrofluoric acid (HF) is only a weak acid, meaning it doesn’t fully dissociate into its ions in water. Even so, it’s probably the most dangerous acid in this list because it’s the one you’re most likely to encounter. This acid is used to make fluorine-containing drugs, including Teflon and fluorine gas.
Is there a pH higher than 14?
It describes how many hydrogen ions (protons) are present in a solution: the higher the pH, the lower the hydrogen ion concentration, and vice versa. But the scale does not have fixed limits, so it is indeed possible to have a pH above 14 or below zero.
Why pH is not more than 14?
The pH range does not have an upper nor lower bound, since as defined above, the pH is an indication of concentration of H+. For example, at a pH of zero the hydronium ion concentration is one molar, while at pH 14 the hydroxide ion concentration is one molar.

Is vinegar an acid?
Vinegar is acidic. Vinegar’s pH level varies based upon the type of vinegar it is. White distilled vinegar, the kind best suited for household cleaning, typically has a pH of around 2.5. … It is the acetic acid content in vinegar that makes it acidic.
Which solution has highest pH?
50.0 mL 0.0500 M calcium hydroxide, Ca(OH)2 (aq) has the highest pH value. Sodium hydroxide and Calcium hydroxide are strong bases so they completely ionize in solution. Because they ionize at the same rate, and Calcium hydroxide has the higher pH calculated, then Calcium hydroxide, in fact, has the highest pH.
What is the lowest pH substance?
Concentrated hydrochloric acid has the lowest pH (0 to 1). There are many other acids as well having a very low pH. … The enhanced hydrogen ion activity is very strong and makes the pH much lower than you’d expect from the acid molarity. Fluoroantimonic acid is so far known as the lowest pH acid.
Is pH of 0 possible?
A solution of a strong acid, such as hydrochloric acid, at concentration 1 mol dm−3 has a pH of 0. … Thus, measured pH values will lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible.
What’s the most acidic thing on earth?
The world’s strongest superacid is fluoroantimonic acid, HSbF6. It is formed by mixing hydrogen fluoride (HF) and antimony pentafluoride (SbF5).
What acid 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 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.
Which is strongest acid?
carboraneThe 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.
