**Choosing a Buffer System for pH 7.41**To effectively buffer a solution at pH 7.41, consider the following options based on their base dissociation constant (\(K_b\)) values:1. **Ammonia** - \(K_b = 1.8 \times 10^{-5}\)2. **Hypochlorite** - \(K_b = 2.6 \times 10^{-7}\)3. **Lactate** - \(K_b = 7.1 \times 10^{-11}\)4. **Hydroxylamine** - \(K_b = 9.1 \times 10^{-9}\)5. **Chlorite** - \(K_b = 8.3 \times 10^{-13}\)These options provide a range of buffering capacities tailored to different pH environments. Select a buffering agent whose \(K_b\) value aligns with the desired pH for optimal buffering capacity and stability.
