Answer:
Generally, the lower the pH, the more sour something is.
Step-by-step explanation:
The comparative degree of sour is a measure of how much more sour one thing is compared to another. To compare the degree of sourness, one can use a sourness scale, such as the Scoville scale, which measures the concentration of capsaicinoids in peppers. Sourness can also be described in terms of pH, which is a measure of the acidity of a solution.
