Bonjour quelqu'un peut-il m'expliquer comment répondre à la question 4C (vrai)  svp

Merci!

salut, tu as des polyanions dans le compartiment de gauche, qui ne peuvent franchir la mb (celle-ci étant imperméable à ces derniers) donc tu auras dans ton bilan d'électroneutralité, ta somme d'anions (Cl et polyanions) qui sera égale à ton sodium 😉
