Calculate the hydronium-ion concentration and the sulphide ion concentration of a 0.1 M `H_2S` solution, `K_1 = 1xx10^(-7)` and `K_2 = 1 xx 10^(-14)`

Explanation

To solve the problem of calculating the hydronium-ion concentration and the sulfide ion concentration in a 0.1 M \( H_2S \) solution, we will follow these steps:

### Step 1: Write the dissociation equations

The dissociation of \( H_2S \) can be represented in two steps:

1. \( H_2S \rightleftharpoons H^+ + HS^- \) with \( K_1 = 1 \times 10^{-7} \)
2. \( HS^- \rightleftharpoons H^+ + S^{2-} \) with \( K_2 = 1 \times 10^{-14} \)
