It is a soft, ductile transition metal which is resistant to corrosion due to the presence of an oxide layer on its surface. It is one of the most common elements found in the Earth’s Crust. It is often found in the pyrochlore mineral.

Follow our policies when asking homework-like questions (questions about problem sets, exam items, etc.). This would be a strong acid too and the inflection point would be that for water at pH 7. Note that the pKa 1.69 is assuming HX+XX− H X + X X − and is taken at 1/2 of the NaX+OHX− N a X + O H X − used. Knowing that HX2SOX4 H X 2 S O X 4 has two protons, the second pKa should be taken at 150% on the plot which would give the correct pKa ...
May 14, 2023 · Acidimetry is the specialized analytic use of acid-base titration to determine the concentration of a basic (synonymous to alkaline) substances using standard acid. Alkalimetry, is the same concept of specialized analytic acid-base titration, but for an acidic substance using standard base. – Poutnik. May 14 at 14:00. 6 Answers. Sorted by: 7. 4.
