WebMay 14, 2024 · What is the pKa value of H2SO4? The pKa value of H2SO4 is approximately -3. The pKa value of HNO3 is approximately -1.3. So HCl is strongest of all. There are some super acids, like fluroantimonic acid, that are 100 times more stronger than sulfuric acid. pKa, Ka, and Acid Strength Watch on Category: Blog WebThe same way you know that HCl dissolves to form H+ and Cl-, or H2SO4 form 2H+ and (SO4)2-. In this example with NH4Cl, the conjugate acids and bases are NH4+ and Cl-. Notice how also the way the formula is written will help you identify the conjugate acids and bases (acids come first on the left, bases on the right) ( 4 votes) Mike 6 years ago
WebYour laboratory is out of materials to make phosphate buffer and you are considering using sulfate to make a buffer instead. The pKa values for the two hydrogens in H2SO4 are -10 and 2.
