$\ce{HClO4}$ is stronger acid due to the formation of more stable conjugate base. My Answer: Is it C6H5NH3+ because its base is Kb= 3.8*10^-10 so its Ka= 2.6*10^-5 which is stronger than 1.0*10^-7 for H2O? 1) Which is the STRONGER acid, H2O or C6H5NH3+? The most common examples of a strong acid are sulfuric acid (H2SO4), hydrochloric acid (HCl), and nitric acid (HNO3). Acidity of Perchloric acid is greater than Sulphuric due to the resonance stability of Perchlorate ion or you can say resonance delocolization. As examples, "HI" is a stronger acid than "HBr"; the primary reason is that "I" is larger than "Br", and makes a weaker bond with "H" (there is a counteracting electronegativity trend, which is not significant here). Some chemists include HCIO3 (Chloric acid), though it is not universally recognized as a strong acid. reason between hclo3 abd hclo4 .hclo4 is strong because it has greater no oxygen atom.more the oxygen atom more electron will be pulled away from o-h bond and the more this bond will be weakened. HCIO4 (Perchloric acid) and HCl (Hydrochloric acid) are definitely strong acids. FALSE. Since HClO4 is considered a strong acid, does it make HClO2 strong too? This mineral acid is known to have an extremely suffocating, acrid odour associated with it. Assume an acid $\ce{HA}$.An acid is strong if. Hre HCLO4is the strongst acid. Write out HnXOm as Om-nX(OH)2 : ClO3(OH) O3 indicates an extremely strong acid; the formal charge on Cl is 3+ and this results in an extremely weak O-H bond and hence H^+ is easily ionized. Perchloric Acid (HClO4) Perchloric acid, a chemical compound with the formula HClO4, is a very powerful mineral acid. Identify HClO as a weak acid,strong acid,weak base,strong base both weak acid and weak base or neither acid or base. First parameter to consider is the polarity of the $\ce{H-A}$ bond. 3) HNO2 is a strong acid. More polar bonds mean less electron density on the bond.  Share. This leads to greater stability. Same goes with H2SO4. HClO4 pka = -8 (strongest of the common mineral acids) H2SO4 pka1 = -3, pka2 = 1.99 (Wikipedia RH panel) These are oxo acids. 2) Which is the WEAKER acid, HClO4 or C6H5NH3+? Follow answered Jan 9 '17 at 12:59. 2) The compound HClO4 is a weak acid. Also there are more number electronegative oxygen atoms in case of $\ce{HClO4}$ , so acidity should be more. Since it is a strong acid, does it make H2SO3 a strong acid … protons are donated easily, i.e., the $\ce{H-A}$ bond is readily broken; the conjugate base $\ce{A-}$ is stable, i.e., $\ce{A-}$ is reluctant to combine back to $\ce{HA}$. It can be noted that this compound has a melting point of 231 Kelvin and a boiling point of 394 Kelvin. 6. There are six common stron acids HNO3,HClO4,H2SO4,HCL,HBr,HI and strong base are all the group Ist hydroxides and the Three of group 2 hydroxides Ca(OH)2, Sr(OH)2 and Ba(OH)2. Improve this answer. Weaker bond = stronger acidity. Yes, HClO4, perchloric acid, is a strong acid. ; When are protons easily donated? My Answer: C6H5NH3+ because HClO4 is one of the strong …
