Final answer:
Bases are substances that can accept or donate an electron pair, while the pH scale measures the acidity or alkalinity of a solution. Sodium hydroxide is an example of a strong base used in cleaning products.
Step-by-step explanation:
In chemistry, a base is a substance that can accept or donate an electron pair, while a use is the practical application or purpose of a particular item or concept. One common practical use of bases is their role in adjusting and interpreting the pH scale.
The pH scale measures the acidity or alkalinity of a solution and ranges from 0 to 14. A pH value of 7 is considered neutral, values below 7 are acidic, and values above 7 are alkaline. Bases are substances that can neutralize acids and increase the pH of a solution.
For example, sodium hydroxide (NaOH) is a strong base commonly used in cleaning products. It can accept hydrogen ions (H+) from acidic solutions, leading to an increase in pH and the neutralization of acids.
