What is the pH of fluoroantimonic acid?
-31.3
The honor of the strongest acid goes to fluoroantimonic acid, which is 100,000 billion billion billion times more acid than gastric acid (pH of -31.3.). This substance is so strong it will eat through skin, bones, and pretty much any container used to store it.
How can you predict the pH of an acid?
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log [H3O+].
How is pH levels measured?
There are two methods for measuring pH: colorimetric methods using indicator solutions or papers, and the more accurate electrochemical methods using electrodes and a millivoltmeter (pH meter).
Is fluoroantimonic acid stronger than magic acid?
The acidity of HSO3F increases from Ho -15.1 to 21.0 on addition of 25 mole percent SbF5. 1:1 Molar composition HSO3F-SbF5 (Magic acid), which I used extensively in my study of carbocations and other systems has an Ho value of about -23. Fluoroantimonic acid is an even stronger acid.
Is fluoroantimonic acid stronger than sulfuric acid?
Fluoroantimonic acid is 2×1019 (20 quintillion) times stronger than 100\% sulfuric acid.
What is the normal pH of gastric acid?
Normal Results 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. Note: Normal value ranges may vary slightly depending on the lab doing the test.
How do you check pH at home?
Place the pH testing strip in a plastic or glass tube. Pour enough of the water you are testing to cover the pH test strip. After a few seconds pull out the test strip and match the colors to the pH color chart. Testing strips need to be kept dry at room temperature.
How can I test my pH without strips?
When you’re ready, simply tear off a small piece of litmus paper and put in urine stream for a few seconds. Or, you can pee into a small cup and dip the paper into your urine that way. Look at the color of your paper immediately and compare with the color chart on your litmus paper.
What does fluoroantimonic acid do to skin?
Once losing its proton, fluoroantimonic acid and most other strong acids ravage other substances, often by ripping electrons from their atoms. If the substance in question is your skin, the acid will often cleave the amide bonds of proteins and the ester groups in fats through a process called hydrolysis.
