Question
Hello. I need to prepare 1 liter of a buffer of 0.1M , pH=6.0. (Acid =HCl, base=Sodium tetraborate)
I have in the lab: 320331 Sigma-Aldrich hydrochloric acid ACS reagent, 37% .
and 221732 Sigma-Aldrich Sodium Tetraborate (Molecular Weight : 201.22 g/mol).
So what quantity of Sodium tetraborate I need to put in the Di-water?
And first I put the sodium tetraborate, and then the necessary quantity of HCl to obtain the desired pH ?
