Molar mass of HClO4 = 100.45854 g/mol. This compound is also known as Perchloric Acid. Convert grams HClO4 to moles or moles HClO4 to grams. Molecular weight calculation: 1.00794 + 35.453 + 15.9994*4.What is the pH of .025 M HClO4-? The pH is the negative of the log of the hydrogen ion concentration. HClO4 is a strong acid and it is 100% ionized. Therefore the hydrogen ion concentration (or hydronium, if you prefer) is 0.025. pH = -log(.025) = 1.6. What is the pH of a solution by mixing 50 ml of 0.4N HCL and 50 ml 0.2 N NaOH? Hydrobromic HBr Br-. Perchloric HClO4ClO4 -. Hydrochloric HCl Cl-. Chloric HClO3ClO3-. Sulfuric (1) H2SO4HSO4 -. Nitric HNO3NO3-. Strong acids completely dissociate in aq solution (Ka > 1, pKa < 1). Conjugate bases of strong acids are ineffective bases. To find the pH, we need to know the Ka and or pKa for HNO2 and then use the Henderson Hasselbalch equation: pH = pKa + log [salt]/][acid]. Looking up pKa for HNO2 we find it to be 3.4 (Wikipedia).
