Question

What is the equation for Hydrogen Sulfide plus Potassium Hydroxide? An equation with the predicted product first and then the complete balanced equation?

A) Predicted product: Potassium Sulfide; Balanced equation: H2S + 2KOH -> 2K2S + 2H2O
B) Predicted product: Potassium Sulfide; Balanced equation: H2S + KOH -> K2S + H2O
C) Predicted product: Hydrogen Hydroxide; Balanced equation: H2S + 2KOH -> K2S + 2H2O
D) Predicted product: Sulfur Dioxide; Balanced equation: H2S + 2KOH -> K2SO3 + 2H2O

Answer 1

The predicted product of the reaction between hydrogen sulfide and potassium hydroxide is potassium sulfide, with the balanced equation being H2S + 2KOH → K2S + 2H2O. The correct option is C.

Step-by-step explanation:

The reaction between hydrogen sulfide and potassium hydroxide is a chemical process in which the acid (hydrogen sulfide) reacts with the base (potassium hydroxide) to form a salt and water. The predicted product of this reaction is potassium sulfide, and the balanced chemical equation is:

H2S + 2KOH → K2S + 2H2O

So, the correct answer is C) Predicted product: Potassium Sulfide; Balanced equation: H2S + 2KOH → K2S + 2H2O.

Similarly, the reaction between hydrogen selenide, which has properties similar to hydrogen sulfide, and potassium hydroxide would result in the formation of potassium selenide and water. The balanced equation is: H2Se + 2KOH → K2Se + 2H2O, with potassium selenide being the salt product of the reaction.
