- ph is defined as the potential of h+ concentration.
- Substances can be diffrentiate as an acid or a base by evaluate where they fall on the pH scale. Some examples of acids include citrus juice and stomach acid. Some familiar of examples of bases include baking soda and lye.
- Acids are the matters that have a pH below 7, while bases are substances that have a ph rating above 7. This is because the ph scale tells the concentration of free hydrogen ions in a substance. Acids have relatively more hydrogen ions, while bases have relatively fewer hydrogen ions and more hydroxide ions. In a substance where the number of hydrogen (H+) ions is equal to the number of hydroxide (OH-) ions, the ph would be considered as completely neutral, and equal exactly 7.
