pH and Benedict's Test on Local and Foreign Oranges

Today we were very excited because we started new tests in the lab!!!

We tested for pH using two methods:

(i) A rough method using Universal Indicator

(ii) An accurate method using a pH meter

The methods for the pH tests are shown here.

We also tested for reducing sugars using the Benedict's Test. The method for this test is shown here.

Here are some snaps from today's experiment:
