WebApr 1, 2024 · As the concentration of boron in seawater is around 4.5 mg/L, it is acceptable that only mononuclear species B (OH) 3 and B (OH) 4- are present in seawater ( Najid et al., 2024b; Zeebe et al., 2001 ). The distribution of two components, boric acid and borate ion, depends on the dissociation constant of boric acid (pK a ). http://barbara.cm.utexas.edu/courses/ch302s09/files/CH302_021609a.pdf
WebSo, now that we're adding the conjugate base to make sure we have roughly equal amounts, our pH is no longer 2. It might be somewhere like a 5. So now we have a strong buffer with a lot of capacity, but our pH of this buffer solution is very different from the pH of just the weak acid/conjugate base we started with. Comment ( 4 votes) Upvote
WebThe concentration of hydroxide ion in a solution of a base in water is greater than 1.0×10 ⁻⁷ M M at 25 °C. The concentration of H ₃ O ⁺ in a solution can be expressed as the pH of the solution; pH=−log H ₃ O ⁺.
