The supply of hydrogen ions will also depend upon their concentration, i.e. the pH of the electrolyte. A concentration gradient in the electrolyte is illustrated. ·If the electrolyte is unstirred, the ...

Nerve cells are the information carriers in our brain. When transferring signals, they change their electrical charge by ...

Like all cells, an excitable cell maintains a different concentration of ions in its cytoplasm than exists in its extracellular environment. Together, these concentration differences create a ...

The pH of a solution is a measure of its concentration of hydrogen ions. The higher the concentration of H + ions in an acidic solution, the lower the pH. A pH of 1 represents a hydrogen ion ...

A RECENT number of the Journal of the Marine Biological Association (vol. xii., No. 4, October 1922) contains a series of papers by Dr. W. R. G. Atkins which make a contribution of conspicuous ...

Take the electrolyte potassium, for example. It is the most abundant positively charged ion inside cells, but its concentration is 30-fold lower in the extracellular environment. "Suddenly an ...

If the hydrogen ion concentration in a solution increases by a factor of 10, the pH of the solution decreases by 1. A solution of 1 g/dm 3. hydrochloric acid has a pH of 1.6. Predict its pH when ...
