If the pH of grapefruit is 3 and the pH of beer is 5, how many times more acidic is the grapefruit juice than the beer? According to the logarithmic scale
Each number on the pH scale is 10x; therefore, a difference of 2 means 100 times.
Oh, we've got ourselves a juicy question here! Let's get down to the "sour" details, shall we?
The pH scale is logarithmic, so each unit represents a ten-fold difference in acidity.
Given that the pH of grapefruit juice is 3 and the pH of beer is 5, we can calculate the difference.
To find out how many times more acidic the grapefruit juice is than the beer, we subtract the pH values: 5 - 3 = 2.
Since each unit represents a ten-fold difference, we can say that grapefruit juice is 10^2 times more acidic than beer.
That means grapefruit juice is a whopping 100 times more acidic than beer! Now that's some serious tangy tartness!
The pH scale is logarithmic, which means that each unit on the scale represents a tenfold difference in acidity. To determine how many times more acidic the grapefruit juice is compared to the beer, we need to calculate the difference in pH values.
The pH of grapefruit juice is 3, while the pH of beer is 5. The difference in pH between these two substances is 5 - 3 = 2.
Since each unit on the pH scale corresponds to a tenfold difference, a difference of 2 units means that the grapefruit juice is 10^2 = 100 times more acidic than the beer.
Therefore, grapefruit juice is 100 times more acidic than beer according to the logarithmic scale.
To determine how many times more acidic the grapefruit juice is compared to beer using the logarithmic scale of pH, we need to calculate the difference in pH values.
The pH scale is logarithmic, meaning that each unit represents a tenfold difference in acidity or alkalinity. For example, a substance with a pH of 3 is ten times more acidic than a substance with a pH of 4.
In this case, the grapefruit juice has a pH of 3, while beer has a pH of 5. To find the difference in pH, we subtract the pH of beer from the pH of grapefruit juice:
3 - 5 = -2
The result is -2, indicating that the grapefruit juice is 2 pH units lower than the beer on the pH scale.
Since each unit on the pH scale represents a tenfold difference, the grapefruit juice is 10 times more acidic than beer for each pH unit. Therefore, to find out how many times more acidic the grapefruit juice is compared to beer, we raise 10 to the power of the pH difference (-2):
10^(-2) = 0.01
This means that the grapefruit juice is 0.01 times (or 1/100 times) more acidic than the beer.
In summary, the grapefruit juice is 2 pH units lower than beer, indicating that it is 10^2 or 100 times more acidic. However, since the pH scale is logarithmic, the juice is 0.01 times (or 1/100 times) more acidic than beer.
