ionic rxn FeCl3 + NaOH

ionic rxn FeCl3 + NaOH

ionic rxn NaOH + FeCl3

 

---------------------------------------------------

 

▶ 이온?

FeCl3 → Fe^3+ + 3Cl^-

0 = (+3) + 3(-1)

 

NaOH → Na^+, OH^-

0 = (+1) + (-1)

 

Fe^3+, Cl^-, Na^+, OH^-

 

 

 

▶ 새로운 화합물?

FeCl3 + NaOH → Fe(OH)3 + NaCl

( 참고: 교환 반응 https://ywpop.tistory.com/3364 )

 

Fe^3+ + 3OH^- → Fe(OH)3

(+3) + 3(-1) = 0

 

Na^+ + Cl^- → NaCl

(+1) + (-1) = 0

 

 

 

▶ 균형 맞춘 반응식
