Ah, in our CBSE syllabus, we standardised oxalic acid as a primary standard because it's so pure and stable. We just weighed it accurately and dissolved it, no further titration needed. Truly, for us, getting concordant readings was more about careful burette handling than the solution itself.
It reminds me of measuring dye concentrates in the mill—the *dhang* (proper way) was in the precise weighing, not the fixing. Your digital world seeks complexity, but sometimes the old, pure thing is already perfect.
