Strong or weak acids

This has to do with the Lewis acids/base and the Bronstead Lowry theory. That the first question has Why is HI a stronger acid than HF? Does it have to do with electronegativity or the size , but not 100%, see the acetic acids.) Use the electronegativity values when discussing electronegativity

Question:Please help? What is stronger a diluted strong acid solution or a concentrated weak acid solution?

Answers:It depends upon concentrations of both acids.... Generally a diluted stronger acid is stronger as it is strong electrolyte too.... but for that its concentration should be above 10^(-4)

Question:strong acids and weak acids names and formulas.

Answers:sounds like someones trying to do their homework. Google is your friend.

Question:for example, how do you know that this acid is weak/strong? HCHO2

Answers:An acid is weak if it fully ionizes in water so it depends on the solubility essentially. HCOOH (the acid you referred to in the question) is methanoic acid, an organic acid All organic acids (carboxylic acids) are weak acids All the mineral acids (HNO3, H2SO4, HCl) are strong acids Other strong acids would include all the acid halides excepting hydrofluoric acid (HF - which only ionizes partially because of the strength of the bond). Therefore HI, HBr, etc. are all strong acids (stronger than HCl) because the ions dissociate readily in water

Weak monoprotic acids can be neutralized in the presence of a strong base (such as sodium hydroxide) to form a buffered solution between the excess acid and the newly formed sodium salt of the conjugate base. As base is added, but before the acid is com... Contributed by: Kristen Aramthanapon and Wiktor Macura
