Решение
3KOH + FeCI3= 3KCl + Fe(OH)3
3K+ + 3OH- + Fe+3 + 3CI-= 3K+ + 3Cl- + Fe(OH)3↓
3OH- + Fe+3 = Fe(OH)3↓
Fe[3+] + 3Cl[-] + 3K[+] + 3OH[-] = Fe(OH)3↓ + 3K[+] + 3Cl[-]
Fe[3+] + 3OH[-] = Fe(OH)3↓
Решение
3KOH + FeCI3= 3KCl + Fe(OH)3
3K+ + 3OH- + Fe+3 + 3CI-= 3K+ + 3Cl- + Fe(OH)3↓
3OH- + Fe+3 = Fe(OH)3↓
