Salut !

comment sait - on que le pouvoir tampon est égal à 1 ?

La réponse est VRAIE mais il n'y a pas d'explication

Tu utilises la formule β= Δ𝑪 /Δ𝒑H

tu as donc dC = quantité de solution ajouté (0,8) et dpH= pH (solution finale )- pH(initial) = 4,6-3,8 

soit au final on obtient 0,8/0,8 = 1 

J'aurais pu faire une blague sur la solution finale, mais on va rester pro 😉
