Question

STANDARDISATION OF 0.1 M HCl

Borax dissolves slowly in water at room temperature. Why do we not use a stirring
rod to mix the solution and speed up this stage of the experiment?

Answer 1

To be honest about it I don't know; however, my best educated guess is that the glass in beakers/stirring rods etc are borosilicate glass and small amounts of glass could be abraded with vigorous stirring and that would affect the standardization.
