Study Notes
pH Definition and Significance
- The 'H' in pH refers to Hydrogen ions (H+).
- The 'p' in pH stands for the power of Hydrogen ions (H+).
pH Scale and Ion Concentration
- A pH value of 2 indicates a highly acidic solution.
- A pH value of 12 indicates a highly basic solution.
- A pH value of 13 indicates an extremely basic solution.
- At pH 7, the H+ ions and negatively charged Hydroxide ions (OH-) are balanced out completely.
- At a low pH value, there are a lot of H+ ions in the water, indicating acidity.
- At a high pH value, there are a lot of OH- ions in the water, indicating basicity.
pH Value Comparison
- A pH value of 3 is more acidic than a pH value of 5, with a 10-fold difference in H+ ion concentration.
- The significance of a pH value of 3 compared to a pH value of 4 is that it indicates a 10-fold difference in H+ ion concentration.
- The significance of a pH value of 2 compared to a pH value of 4 is that it indicates a 100-fold difference in H+ ion concentration.
Ion Charges and pH
- The Hydrogen ion (H+) has a positive charge.
- The term 'H+' represents the positively charged Hydrogen ion in the context of pH.
