KOH and ZnCl2
KOH(aq) + ZnCl2(aq) →
double displacement reaction:
KOH(aq) + ZnCl2(aq) → KCl + Zn(OH)2
▪ Cl- are soluble except when paired with Ag+, Pb2+, Cu+, Hg22+
▪ KCl → soluble → aqueous
▪ Hydroxides (OH-) insoluble except when with Group 1A ions (Li+, Na+, K+, etc.) and ammonium ion (NH4+) and Ca2+, Sr2+, Ba2+
▪ Zn(OH)2 → insoluble → solid/precipitate
Balanced reaction equation:
2 KOH(aq) + ZnCl2(aq) → 2 KCl(aq) + Zn(OH)2(s)
For the total ionic equation → soluble ionic compounds (in aqueous form) separate or breaks up and become ions
• Solids, gases, and liquids will not break up since they are insoluble compounds
Total ionic equation:
What is the net ionic equation for the reaction that occurs when aqueous solutions of KOH and ZnCl2 are mixed?
