Is hf a monoprotic acid
Web(b) The acid and titrant are both monoprotic and the sample and titrant solutions are equally concentrated; thus, this volume of titrant represents the equivalence point. Unlike the strong-acid example above, however, the reaction mixture in this case contains a weak conjugate base (acetate ion). WebA buffered solution resists changes in pH when acids or bases are added or when dilution occurs. See Table 10-2 for other examples of buffers.

Web- The answer is 0.120 M. Is this correct? (.025L) (0.115M)=0.002875 moles NaOH 0.002875 mol/0.025 L But shouldn't you A 25.0 mL sample of a solution of a monoprotic acid is titrated with a 0.115 M NaOH solution. The titration curve above was obtained (equivalence point at 25 mL NaOH). WebHydrofluoric acid (HF) is the most effective mineral acid for breaking up strong Si–O bonds to form SiF6− 2 ions in acidic solution. Silicates are converted to volatile SiF 4, which will be lost in open vessel digestion procedures. HF by itself is more effective in the digestion of silicate rock minerals than when mixed with another acid.
WebAug 14, 2024 · The hydrogen sulfate ion ( HSO − 4) is both the conjugate base of H2SO4 and the conjugate acid of SO2 − 4. Just like water, HSO4− can therefore act as either an acid or a base, depending on whether the other reactant is a stronger acid or a stronger base.
