Question

calcule as concentrações molares dos íons presentes nas soluções 0 002

Answer 1

a)H+=0,0002 mols /Cl-=0,0002 mols

b)Ba²+=0,0002 mols/(OH)-=0,0004mols

c)AL³+=0,002mols/(NO3)=0,006 mols

Answer 2

Resposta:

a)H+=0,0002 mols /Cl-=0,0002 mols

b)Ba²+=0,0002 mols/(OH)-=0,0004mols

c)AL³+=0,002mols/(NO3)=0,006 mols
