How To Measure The Acidity Of Fruits

The pH scale is in the range from 0 to 14 and determines how basic or acidic a solution is. The neutral media has pH 7. Values below 7 correspond to acidic solutions. The majority of fruits contains various organic acids and hence the fruit pH falls into the acidic range between 2 and 6. Acidity of fruits can be determined relatively easy using pH paper. Avoiding high-acid fruit and food may especially help people with digestive or dental problems.

Step 1

Wash fruits with water and then dry them using paper towels.

Step 2

Cut a piece of fruit in half using the knife. Put both halves on the plate.

Step 3

Cut a 1-1/2-inch piece of the pH paper.

Step 4

Take one fruit half and firmly press the piece of the pH paper against the cut side of the fruit.

Step 5

Compare the color of the paper strip with the standard pH scale printed on the pH paper pack to determine the acidity of this fruit.

Step 6

Repeat Steps 2 to 5 for the other fruits.
