Find out 10 strong and weak acid with example
  • 1 answers
1.Strong Acids Strong acids dissociate completely into their ions in water, yielding one or more protons (hydrogen cations) per molecule. There are only 7 common strong acids. 1.HCl - hydrochloric acid 2 HNO3 - nitric acid 3H2SO4 - sulfuric acid (HSO4- is a weak acid) 4.HBr - hydrobromic acid 5.HI - hydroiodic acid 6.HClO4 - perchloric acid 7.HClO3 - chloric acid Examples of ionization reactions include: 8.HCl → H+ + Cl- 9.HNO3 → H+ + NO3- 10.H2SO4 → 2H+ + SO42- Note:1.the production of positively charged hydrogen ions and also the reaction arrow, which only points to the right. All of the reactant (acid) is ionized into product. 2.Weak Acids Weak acids do not completely dissociate into their ions in water. For example, HF dissociates into the H+ and F- ions in water, but some HF remains in solution, so it is not a strong acid. There are many more weak acids than strong acids. Most organic acids are weak acids. Here is a partial list, ordered from strongest to weakest. 1.HO2C2O2H - oxalic acid 2.H2SO3 - sulfurous acid 3.HSO4 - - hydrogen sulfate ion 4.H3PO4 - phosphoric acid 5.HNO2 - nitrous acid 6.HF - hydrofluoric acid 7.HCO2H - methanoic acid 8.C6H5COOH - benzoic acid 9.CH3COOH - acetic acid 10.HCOOH - formic acid Weak acids incompletely ionize. An example reaction is the dissociation of ethanoic acid in water to produce hydroxonium cations and ethanoate anions: CH3COOH + H2O ⇆ H3O+ + CH3COO- Note:2.the reaction arrow in the chemical equation points both directions. Only about 1% of ethanoic acid converts to ions, while the remainder is ethanoic acid. The reaction proceeds in both directions. The back reaction is more favorable than the forward reaction, so ions readily change back to weak acid and water.
