Strong acids are acids that dissociate readily from their hydrogen ion(s).
Examples include: Strong acids
HCl, hydrochloric acid
HNO3, nitric acid
HI, hydroiodic acid
H2SO4, sulfuric acid
HBr, hydrobromic acid
HClO4, perchloric acid
HClO3, chloric acid
Weak acids do not dissociate readily from their hydrogen ions. They, therefore, act weakly as an acid. All edible acids are, naturally enough, weak acids.
Examples include:
Weak acids
HCN, hydrocyanic acid
(COOH)3C3OH, citric acid
tartaric acid, lactic acid, oxalic acid ...

∙ 13y agoThe pK-values determine the difference between strong and weak acids in water:
- Strong acid have pKa,strong < 0.0 (so negative values!)
- H3O+ is the 'shifting' value of pKa = 0.0
- Weak acids have by definition pKa,weak > 0.0 (positive)

Can every strong electrolyte be considered a strong acid?
No. Many strong electrolytes are bases or neutral salts.
How are strong acids converted to weaker ones?
Buffer systems. They convert strong acids or bases into weak acids or bases.
Can strong and weak acids be determined by using an indicator?
yes
Is NO3 a weak or strong acid?
This is based on acids. HNO3 is a strong acid.
The metabolic processes usually adds acids or bases to the blood?
It adds Acids to the blood, and they are Strong.
What is true about weak acids as compared to strong acids?
Weak acids have a larger value of pKa than strong acids
Are organic acid weak or strong?
True organic acids are weak acids but alpha substituted acids may be strong as 'trichloric acetic acid is a very strong acid.
What is the lowest pH to the highest pH?
Lowest pH, strong acids, then weak acids, then salts of strong acids and strong bases, then salts of weak acids and strong bases, then weak bases, then strong bases. All very confusing!
Are acids used strong or weak?
acids are of types.....concentrated acids are strong.
Are the the acids and proteins found in DNA weak or strong?
Weak Acids
What is the difference between a weak and strong acid involves the acids ability to do what?
The acids ability to disassociate completely in solution. Strong acids do and weak acids do not.
Which has a lower pH weak acids or strong acids?
strong acid
Are mineral acids weak?
Mineral acids are strong acids.
What is the difference a weak and a strong acid involves the acid ability to do what?
The acids ability to disassociate completely in solution. Strong acids do and weak acids do not.
Is washing up liquid a weak or strong alkali?
it is weak and strong because it neutralises acids. So its strong not weak but weak not strong.
Would you expect strong acids or weak acids to have a lower pH level?
strong acids
Differentiate between a strong acid and weak acid?
Strong acids dissociate completely in aqueous solution; weak acids do not.
