WebbAs you learned in Chapter 4 "Reactions in Aqueous Solution" and Chapter 8 "Ionic versus Covalent Bonding", acids and bases can be defined in several different ways (Table 16.1 "Definitions of Acids and Bases").Recall that …

WebbStrong acids (such as HCl, HBr, HI, HNO₃, HClO₄, and H₂SO₄) ionize completely in water to produce hydronium ions. The concentration of H₃O⁺ in a strong acid solution is therefore equal to the initial concentration of the acid. For example, a solution of 0.1 M HNO₃ contains 0.1 M H₃O⁺ and has a pH of 1.0. Created by Jay. WebbpH is defined for expressing H 3 O + concentration and pOH is defined for expressing OH-concentration in an aqueous solution. In calculating pH of NaOH solution, first, we have to calculate the pOH value. We have a relationship between pH and pOH as below. pH + pOH = pKa. pKa is a constant to a certain temperature and pKa = 14 at 25 0 C. So at ...
