🤓 Based on our data, we think this question is relevant for Professor Sotelo Munoz's class at TEXAS.

FREE Expert Solution

aqueous hydroiodic acid → HI(aq)

aqueous calcium sulfide → CaS(aq)

HI(aq) + NaOH(aq) → 

double displacement reaction:

Reaction:

HI(aq) + CaS(aq) → H2S + CaI2

Product:

H2S

H2→ gaseous

CaI2

I- are soluble except when paired with Ag+, Pb2+, Cu+, Hg22+
▪ CaI2 → soluble → aqueous

Balanced reaction equation: 

2 HI(aq) + CaS(aq) → H2S(g) + CaI2(aq)


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:
