Detailed Solution

The axoplasm inside the axon contains low concentration of Na⁺, high concentration of negatively charged proteins.

Resting axoplasm typically has a low concentration of sodium ions (It is high in ECF). Sodium plays a crucial role in the generation of action potentials. When a nerve impulse is initiated, sodium ions flow into the axon, which is a key step in depolarising the membrane and propagating the action potential.
The axoplasm contains a high concentration of negatively charged proteins, such as large anionic molecules. These negatively charged proteins help maintain the resting membrane potential of the neuron. At rest, the inside of the neuron is more negatively charged compared to the outside, which is essential for the excitability of the cell.
