Question
**Charge-Balance Equations for Solutions:** a. **0.15 M in HF** - \[ \text{[H}^+\text{]} = \text{[F}^-\text{]} + \text{[OH}^-\text{]} \] b. **0.16 M in (CH₃)₂NH** - \[ \text{[CH₃)₂NH₃}^+\text{]} + \text{[OH}^-\text{]} = \text{[CH₃)₂NH]} \] c. **Saturated with Ag₂CO₃** - \[ 2\text{[Ag}^+\text{]} + \text{[H}^+\text{]} = \text{[CO₃}^{2-}\text{]} + \text{[HCO₃}^-\text{]} + \text{[OH}^-\text{]} \] **Explanation:** These equations illustrate the charge balance in different chemical solutions. - For HF solution, the hydrogen ions (\[\text{H}^+\]) balance with fluoride ions (\[\text{F}^-\]) and hydroxide ions (\[\text{OH}^-\]). - In the solution of dimethylamine ((CH₃)₂NH), the positively charged ions (\[\text{(CH₃)₂NH₃}^+\]) are balanced with dimethylamine and hydroxide ions. - For a solution saturated with silver carbonate (Ag₂CO₃), the silver ions and hydrogen ions together balance the carbonate or bicarbonate ions and hydroxide ions. The equation also accounts for potential equilibrium shifts that produce bicarbonate (\[\text{HCO₃}^-\]).
