Salut @emmmmaaa!!!

 

Il doit s'agir d'un acide faible ducoup tu n'utilises pas la même formule pour calculer le pH (mais on ne vous la donne pas cette année) 

 

pH = 1/2 (pKa - logC) 

pH = 1/2 (1-log10-3) = 2 

 

J'espère que tu comprends mieux 

N'hésites pas si tu as d'autres questions

 

Bon courage 💪
