What is the most powerful 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 a higher pKa more acidic?
Higher pKa indicates weaker the acid. Lower the pKa value stronger the acid is.
How does pKa relate to acidity?
The pKa value describes how many acidic ions a substance will produce in a solution. … The sulfuric acid solution will be more acidic because the sulfuric acid loses more protons to produce more hydronium (H3 O+ ) ions. Similar to pH, the lower the pKa, the stronger the acid.
Why is a lower pKa more acidic?
A lower pKa means the Ka value is higher and a higher Ka value means the acid dissociates more readily because it has a larger concentration of Hydronium ions (H3O+).
What does pKa strongest acidic mean?
Regarding to your question, the strongest acidic pKa refers to N-H dissociation of the indol part, while the strongest basic pKa refers to the dissociation of the protonated tertiary base.
Does high pKa mean low pH?
The lower the pH, the higher the concentration of hydrogen ions [H+]. The lower the pKa, the stronger the acid and the greater its ability to donate protons. pH depends on the concentration of the solution. This is important because it means a weak acid could actually have a lower pH than a diluted strong acid.
