Description of a nerve signal
The nerve signal, or action potential, is a coordinated movement of sodium and potassium ions across the nerve cell membrane. Here's how it works: As we discussed, the inside of the cell is slightly negatively charged (resting membrane potential of -70 to -80 mV).

Answer:
HCOOH, H₃O⁺, and HCOO⁻
Explanation:
HCOOH is the major solute.
However, HCOOH is a weak acid. It dissociates slightly in aqueous solution.
HCOOH + H₂O ⇌ HCOO⁻ + H₃O⁺
Thus, two other solute particles are HCOO⁻ and H₃O⁺.
