What is the primary difference between acids and bases in terms of their effect on hydrogen ion concentration in a solution?
Acids increase the concentration of hydrogen ions (H+) in a solution, while bases decrease the concentration of hydrogen ions. How does hydrochloric acid (HCl) behave when added to water, and what effect does this have on the solution?
When hydrochloric acid (HCl) is added to water, it dissociates into hydrogen ions (H+) and chloride ions (Cl-), increasing the hydrogen ion concentration in the solution. Describe the process by which sodium hydroxide (NaOH) acts as a base when dissolved in water.
Sodium hydroxide (NaOH) dissociates in water to form sodium ions (Na+) and hydroxide ions (OH-); the hydroxide ions react with hydrogen ions (H+) to form water, thereby decreasing the hydrogen ion concentration. Why is the concentration of hydrogen ions important in biological systems?
The concentration of hydrogen ions is crucial because it strongly affects many biological processes, influencing the chemical environment within living organisms. What does the notation [H+] represent in the context of acids and bases?
The notation [H+] represents the concentration of hydrogen ions in a solution. What is the primary difference between acids and bases in terms of their effect on hydrogen ion concentration in a solution?
